Title: Gigabyte P67A-UD4-B3 Rev1.1 Motherboard loops on startup
Post by: sbp on May 14, 2011, 03:41:47 pm
NZXT Phantom Enthusiast Black Full Tower Case

Intel Core i5 2500K Unlocked, 1155

Gigabyte P67A-UD4-B3 Rev1.1 Motherboard.

Corsair Hydro Series H70 High-performance(BRACKETS ARE BROKEN SO IM USING STOCK COOLER INSTEAD)

Gigabyte GTX 560 OC 1GB GDDR5 Dual DVI Mini HDMI Out PCI-E Graphics Card

8GB DDR3 1600MHz (2x4GB) Corsair Vengeance Blue

OCZ Agility Series 60GB 2.5" SATA-II Solid State Hard Drive

Western Digital Caviar Blue 500GB SATA 6Gb/s 16MB Cache - OEM

Corsair 750W HX Modular PSU

Asus Xonar DG 5.1 PCI Surround Sound Card

Tenda Wireless-G PCI Adapter


Ive started my build again just using my PSU, Motherboard, CPU and stock cooler and Memory

Ive placed a flat cardboard sheet on the floor which Ive placed my motherboard and PSU.  Also attaching the CPU, stock cooler and the memory. When I turn on the system I get a blink of lights turn on (PHASE LED) and fans starting up for 1 second and then turning off immediately. I dont understand whats going wrong. The whole computer was working 5 minutes ago before when I was using the h70 cooler, but I decided to take it off since the temperatures were getting high and I think the contact was not great between the cooler and the CPU. So i decided to use the stock coolers.

Why is it not working with the stock cooler? I think I am sure it is not short circuiting because ive placed all the components onto the cardboard and I am not using the case (except the power switch). Could it be that I have applied too much arctic silver 5 paste onto the CPU? Should I clean it and reapply the paste? I have no idea whats going on.

EDIT: I have changed the PSU and the same thing is happening, so im quite sure its not a powersupply issue.

Hi

You sound like you have a bit of a problem there.  Is there any chance that something else got damaged when the brackets broke for the H70 ? Either on top ofr beneath the motherboard.

Have you made sure that you have both the 24 pin and the 8  pin 12v connectors inserted properly ?

Post by: sbp on May 14, 2011, 05:30:15 pm
Yes I have inserted both the 24pin and 8pin cables from the power supply to the motherboard.
 
How can I check to see if its damaged? Look for scratches or..? Also could it be that I have applied too much thermal paste or that the thermal paste has gotten onto the motherboard which may stop it from powering up? Any help will be appreciated?

Post by: Dark Mantis on May 14, 2011, 06:49:14 pm
Either of these could be the problem.

Thermal paste wise you need to start with it all cleaned off. Just a piece of dry kitchen towel will work or add a drop of Isopropylalcohol will help but be careful with it. Once both surfaces are spotless apply a small amount about the size of a grain of rice to the centre of the CPU and carefully bed the heatsink onto it.

If you are using the stock cooler make sure that all 4 locating posts are locked into position and firm. This is a common mistake.

Make sure that you remember to connect the fan to the motherboard.

If you still have a problem post back.

Thanks but not a lot of help really. I thionk that the next thing is to clear the CMOS and then try again. Please follow these directions exactly.


Remove the power cable from the mains supply and then press the power switch on the case for a few seconds just to drain any residual energy in the PSU capacitors.

Once done remove the motherboard battery for at least one hour before replacing it.
 
Next plug back into the mains supply and boot.
 
You will now need to enter the BIOS by pressing DEL and load Optimised BIOS Defaults.

Make any other changes to the BIOS settings to suit your self like disabling the floppy drive, disabling the full screen logo and making the HDD the primary boot device and then press F10 to save and exit.

should this enable the pc to run for over 1 second before turning straight back off again?

Well that is what we are aiming for. ;) Don't lose hope yet we are only just beginning to look into the problem. As it is late now I would suggest doing an extended clear on the CMOS and leave the battery out overnight.

The next thing is to remove the motherboard form the case and test it on the workbench.

Make sure that you observe anti-static precautions.

Lay some cardboard or use the motherboard box that is non-conductive on the worktop and remove the
motherboard/CPU/heatsink/fan/buzzer/one stick of memory and PSU
from the case and put it on the cardboard.

Add the keyboard and now I know you haven't got any graphics but try and boot.
The system should try and then fail emitting a series of beeps. Please post what sounds it makes.

Ive tried this before and it does not work. Just tried it now again except using 1 stick of memory and the same thing happens (using the exact same setup as shown in the video above)

What slot is your memory stick in ?

The next thing would be to check for any bent pins on the CPU socket. Please follow these instructions and take som every clear macro closeup shots preferably without  the flash but good lighting.

Take all the usual anti-static precautions.

Very carefully remove the heatsink and fan. Probably a slight twisting motion is best to release the two as the thermal paste can act like a glue.

Once off remove the CPU taking extreme care both physically and electrically(static) and place somewhere safe.

Make sure that the lighting is very good and even.

Now scrutinise the socket for any pins that are out of alignment, even slightly.
If in any doubt whatsoever take a couple of macro (close up) photos of the socket and post them on here for us to check.

Also look at the bottom of the CPU at the lands (little copper circles) and make sure that there is a mark in each somewhere near the centre.
If there are any missing marks or any of the pins are obviously bent then that is your problem.

Before refitting the CPU clean off all residue of the old thermal paste and the same on the heatsink and then apply a small amount (about the size of a grain of rice) to the centre of the CPU once it is inserted in the socket.

I dont think that the CPU pins are bent in anyway because I previously used the corsair H70 which worked but the contact between that h70 and the CPU was not great because 1 pin was broken and the 2nd was slightly loose so my temperatures were getting quite high (80+ at idle) so i switched it off immediately and decided to use the original heatsink. I took off the H70 and removed the thermal paste, reapplied it with the original heatsink and then it stopped working (this was within 5-10minutes).

Here are those pictures I cannot see any bent pins on the motherboard or the cpu. take a look.

I think I may need to RMA the motherboard. If I do how long do you think the process will take? (I live just outside central london)

Did you use fresh new thermal paste when you reset the heatsink after the H70 ?

The photos are not that good to be honest and it is difficult to make certain whether any pins are bent or not but looking at the lands underneath the CPU there are several that are suspect to say the least.

You will need to PM runn3R and see if he can arrange a RMA for you. Hopefully he will be able to arrange a one off repair but it is up the the company as this isn't really covered under warrantee.

Have you tried clearing the CMOS for an extended period of time?   I would for sure!  Unplug the PSU from the wall, then press and hold the case power on switch for one minute, then remove the CMOS battery and place a jumper on the clear CMOS pins.  Then let it sit for 3-4 hours to overnight, then put it all back together and try again.

The socket and CPU look fine to me, and it's normal for CPU's to look that way DM I have plenty with several marks way off and they all work.  Pressure just might not be strong enough in all areas to make a indentation, but without bent pins they should all make contact just fine and I don't see any bent pins - although only the first image is semi-good enough to see them all, it looks ok from what I can see.  Better socket images would help for sure!   He may just need to reseat the CPU a few times and try again, but I'd for sure clear CMOS too just to be sure.

Did you ever test with the H70 installed again?   Do that too, maybe your stock cooler is not installing correctly so the board shuts down instantly due to heat.

Thank you for the reply, I will try an extended CMOS (i tried for just over an hour) next weekend, as I have exams this week. And I dont think I can try using the H70 cooler because 1 of the pins is broken and the mounting bracket is annihilated. And before I took it off, temperatures were reaching 80/90+ at idle with no overclock which I think is due to the cooler not being in good contact with the CPU. But I will try again, thank you.

Hi Lsdmeasap

I take your point about the pin marks on the lands but there seemed to be an excessive number with no marks at all and I have had CPUs that have shown this as a problem. Anyway I agree that better pictures would be a great help.

We did try a CMOS clear but only for an hour or so and possibly an extended clear might work.

I am also wondering if the CPU itself might be damaged as the temperature could easilly have gone over Tmax without the OP even realising it.

Isnt there a built in safe guard for this? and possibly the CPU is damaged because temperatures I saw reached 90 degrees on 1 or 2 cores. what is the threshold for i5 2500k?

Yes there is a thermal shutdown that is enabled through the BIOS that is supposed to cut out the CPU if it goes over the temperature ceiling but whether it would work fast enough in this sort of scenario I am not sure. Normally there would be a heatsink attached to the CPU which would work albeit  only passively if the fan stopped or similar occurance.

TMax is 99C

Hi sbp

Thanks for PM.
I have checked the videos you put on YouTube but I can't find :o VGA installed on the MB there. Why it is missing?

Please try such method (modified DM's way):

Remove the power cable from the mains supply, leave only 1 stick of RAM and then press the power switch on the case for a few seconds just to drain any residual energy in the PSU capacitors.
Once done remove the motherboard battery for around 15 minutes hour.
Short CLR_CMOS pins by screwdriver or metal jumper for a few seconds, then remove jumper.
Replace the battery.
Next plug back into the mains supply and try to boot. Please note you may see up to 12 short restarts (like you've already seen) before the board starts again.
Then please try to add second stick in Dual Channel. Let us know result.

Yes there is a thermal shutdown that is enabled through the BIOS that is supposed to cut out the CPU if it goes over the temperature ceiling but whether it would work fast enough in this sort of scenario I am not sure. (...)

I am sure, otherwise what's the point?

I have taken out the video card because I just want to check the main components are working, which they clearly are not. I am quite sure the powersupply is working fine because I tested another powersupply which resulted in the same problem. The memory has not been touched and am quite sure is working fine. This leaves me to believe the problem lies between the motherboard, cpu and the cooler. I have requested an RMA for the cooler (because mounting bracket screws are broken) and will test when I get back home this weekend and thank you for the replies.

Hi

Often people are asked to do specific things by whoever is helping them and they might sometimes seem to be irrellevant but there is a reason for doing it that way, hence runn3R asking you to leave only one stick of RAM in while testing.

The point is that it will help save the chip in normal circumstances which doesn't normally include not having a heatsink attached!  I for one wouldn't be happy to run a system that was complete apart from the CPU cooler.  :o

Yes I did wonder if he might confuse you by saying this. Just forget about the jumper and use a screwdriver or tweezers or anything similar which is conductive. Short the two pins out and wait for a few seconds before removing the screwdriver or whatever else you have used. You can then replace the battery after about an hour.

After that go into the BIOS and load Optimised BIOS Defaults. Make any other changes that you want to while you are there and then save and exit (F10).

No luck at all, I did exactly word for word what Runner asked me to do and the same thing happens. All I get is a quick flash of LEDS from the Phase LEDS and also the PSU and Cpu cooler fan start up and then 1 second later, it all stops and thats it. If I keep pressing the power switch on the case (with a few seconds pause in between each press) I can get it to start it up all again and then stop as previously done.

That's what happen to my UD7 the other day after I left it with power disconnected and battery removed overnight. Was able to start it again only after disconnecting the 24-pin ATX connector and force start the PSU shorting green and black pins. Plug it back in and board started OK.

Firstly I take out the battery and leave it out overnight.


Then in the morning, all I do is make a paperclip into a U shape and put 1 pin into the green and the other end I put into ANY black point? and then plug the PSU into the mains and turn it on? for how long? then turn it off and try to start it again?

Disconnect the 24-pin ATX from the motherboard and then short green and any black pins starting the PSU only for some seconds just to make sure it starts. Then plug the 24-pin ATX back in and try to start the system with the power button.

Hi

I would recommend the first thing to do is to clear the CMOS properly. Please follow these instructions exactly.


Remove the power cable from the mains supply and then press the power switch on the case for a few seconds just to drain any residual energy in the PSU capacitors.

Once done remove the motherboard battery for at least one hour before replacing it.
 
Next plug back into the mains supply and boot.
 
You will now need to enter the BIOS by pressing DEL and load Optimised BIOS Defaults.

Make any other changes to the BIOS settings to suit your self like disabling the floppy drive, disabling the full screen logo and making the HDD the primary boot device and then press F10 to save and exit.

   CM Storm Sniper
   Hitachi 0F12115 2TB Sata 6GB
   
– Both have booted and run for several days while we did stress tests on the disks
   We used only 4GB of RAM for the tests.
   FW and drivers were updated to the latest on both PCs before the disk tests.

– After a weekend where both remained shutdown, they both presented the looping boot problem.

Things I've tried so far:

– 1 and 2 RAM in all possible combinations (with 4 different RAM modules).  I also tested the
   RAM modules on other computer and they are OK.
– did all the sugested procedures regarding battery, clear CMOS, draing capacitors, clip test for
   the PS, etc.
   Even switched the battery with a new i5-2500 P67A-ud3-b3 (that is working).
– switched the Graphics card for Sapphire HD5570.
– let the boot loop repeat for over 20 times.
– reinserted all MB cables.
– switched the disk SATA cables and connectors and disks.

During the loop, all MB leds light up briefly, all fans (Case, cooler and Graphic cards) turn on.

Reading this thread (and on other sites) and considering all the tests made, I think the problem is not:
– PS (energy related issues)
– RAM
– Graphics card
– Processor and its connection to the MB.
   I used Artic Silver5 and both PCs run for several days
– Disk and its connections

The culprits can be the Corsair H60 or the MB.

I have not seen any complaints on the Corsair forums, and by exclusion, the MB may be condemned …

Can you help me short out this issue? 

What was the outcome of the other users that had the same problems?

Thanks in advance,

Please don't take this the wrong way but I feel that there is a lot of assumption in your post. I think that you really need to start from scratch with just one machine at a time. If you are willing to do this then I would suggest as a start:

The next thing is to remove the motherboard from the case and test it on the workbench.

Make sure that you observe anti-static precautions.

Lay some cardboard or use the motherboard box that is non-conductive on the worktop and remove the motherboard/CPU/heatsink/fan/buzzer/one stick of memory and PSU from the case and put it on the cardboard. Add the keyboard and now I know you haven't got any graphics but try and boot. The system should try and then fail emitting a series of beeps. Please post what sounds it makes.

If that boots successfully then add the GPU and reboot.
