hi, my pc wont boot.when powering up the case fans,cpu fan, graphics card and hd spin then stop almost immediately then tries to boot up again.This sytem has been stable for about 7 months with no new additions and i have a surge protector.The pc was running overnight while i was downloading, in the morning it had black screen and unresponsive so had to power down at the wall reboot and has been stuck in boot loop since
What i have tried
remove memory and try only 1 at a time
disconnected all the hard drives, try to start pc, reconnect them and then power up again
remove the battery and clear cmos
try boot machine up without graphics card in
tried a power supply from another pc,still the same
booted another pc up using the power supply from my pc.psu seems ok.
power down holding button in till it wont boot, remove all usbs,switch off power supply, clear cmos and rebbot
I'm wondering if its the processer or motherboard but i dont have another processer ,to rule the processer out. its a i5 2.66(mildly overclocked it to 2.9) and the motherboard is a gigabyte ga p55m ud2 and they are both about 7 months old. I dont think the processer ran much over 50 degrees when gaming as it had an after artic cooling freezer 7 pro on the processer.
is there any way i can find out whether or not it is the the board or processer giving me the problem?

Hi and welcome to the forum. You seem to be in a bad place. You have done all the normal things I would have advised already. As you say it would seem to be either the CPU or the motherboard, problem is neither is easy to determine. Have you got a buzzer attached?
-
hi thanx for swift reply, much appreciated. no i dont have a speaker but i gave a case to my bro which has one and can borrow that and put it on my pc.I also removed the hsf and made sure it was seated correctly.
-
Right well do that and then post back or even buy one only a matter of pence and very useful anyway. I take it that you replaced the thermal compound? Also to save yourself time I would apply for an RMA now so if we can't sort it you can send it straight off.
-
Can you try another graphics card or try that graphics card in another computer.? trying to boot up without a graphics card in is not a good test as the board needs a graphics card in to boot.
-
Whilst you are correct Peter in what you say the board will try and boot without the GFX card and will emit a beep code to let you know that it has stopped because of the missing card. So it can still be a useful tool in determining the problem.
-
Thanx, for replies.yes i reapplied the thermal compound again. attached the speaker and i get no beeps whatsoever. All i get is a faint click as the fans start to turn.. i have not tried the graphics card in another pc or tried a diiferent one in mine.

OK then disconnect your PSU and test it. The easiest way is shown on this video.

This is to test the PSU not really the graphics card and the OP said the PSU was tested in another system.
-
Yes I know Peter but you have to start somewhere and the beginning is always good. I don't like to make any assumptions as I have been caught out before.

Mostly only happens when the OP lies about what was tested. ;D
attached the speaker and i get no beeps whatsoever.
Is the speaker in the right way? with the card or ram out do you get any beeps?
-
i know for sure the speaker works, black wire on was - on board and testesd with card and ram out also tried it the other wway round.
ok i tested the power supply as shown in video with everything thing disconnected. when switching on the caes fan and psu fan turned and then the psu popped and is totally dead...oh dear

Normally when a PSU goes pop (lets say it did that and that was the reason why your system does not start) it does not go pop a second time...and you said “booted another pc up using the power supply from my pc.psu seems ok.”....so much for that video but hey just say to Corsair you tested the PSU like in their video and you should get a new one. :D
-
Sounds like the PSU was faulty then.Just lucky your system wasn't connected to it when it blew. :o
Now Peter can you see why I ask to start from the beginning ;)
As Peter quite rightly said though, you tested it out properly and should RMA it.
-
cheers guys, got confirmation for rma from corsair, will let u know outcome when i get psu back
-
Now Peter can you see why I ask to start from the beginning ;)
booted another pc up using the power supply from my pc.psu seems ok.
How can the PSU be faulty if it booted another PC.
And yes the PSU is faulty NOW because running PSU unloaded is a big stress and thats why it popped.
-
regarding the psu, would i be be better off sending this to corsair in holland or back to ebuyer. the psu is about 7 months old?
-

The PSU wasn't run unstressed Peter. He had a load on it(case fan) ;)
I would return it to Ebuyer they are normally very good and I would suspect quicker that shipping it to Holland. After all your contract is with them as retailer for the first twelve months, then it reverts to Corsair for the remainder of the waqrranty period (4 more years I think)
-
The PSU wasn't run unstressed Peter. He had a load on it(case fan) ;)
Still not enough even though the PSU has an internal load which is either fixed or on an automatic circuit that removes the load when the load gets higher so that the PSU powers on, with just a case fan the minimum load would still be minimum and likely popped the internal load for the PSU.

Well he followed Corsair's instructions to the letter as that is how they advise to test their product so I don't think they will be complaining about that. You can see the video for your self at:

Sure it was done as shown but here's the thing:
It did not pop when the PSU was tested in another PC.
It did not pop when the OP was testing it in their system when it was plugged in with the card, ram or HDD's connected or taken out.
IT popped when doing the paper clip test with a case fan... YES?
Not all PSU are made well and all the same and this paper clip test with a case fan should of worked and the internal load was likely not fitted on a heatsink properly which popped the load.
-
No one is argueing over the possible outcomes of this test or whether in theory it is sound, only that he followed their test procedure and so there shouldn't be any problem with RMAing it. When he gets a new one then he knows that it is ok. 8)

Hi recieved new psu today and i still have exactly the same problem. I also tried this with the new psu, which i got off gigabyte technical support
1) Remove the M/B from the case.
2) Only install the basic components on the motherboard – CPU, CPU cooling fan, one memory module, VGA card (if there is no VGA onboard) and power supply.
3) Reset the CMOS once - Disconnect the power cord from the power supply & detach the CMOS battery for 5 minutes then put it back.
4) Connect the internal speaker.
5) Turn on the power to see your system can power up. (Connect only the power switch from the case to the M/B)
Looks like I will have to RMA the motherboard back to ebuyer. Cant fault ebuyer with their rma on psu, picked up tuesday, and delivered today and no hassle whatsoever
cheers for replies
-
Thanks for keeping us up to date anyway. Please let us know what happens next.
-
Did you check the VGA card in another computer? Its likely the motherboard thats the problem but wouldn’t hurt to test it.
-
Bollox, ebuyer mailed to say nothing wrong with m/board.Haven't checked the graphics card in another pc yet
-
Well at least look on the bright side that is another piece of kit that you now know is working. So you have PSU, motherboard. That's a good start. When you get it back post here and we will test it outside the case.
-
Cant fault ebuyer, motherboard back today. Okay i checked the graphics card in my bro's pc and it is fine.
-
OK. Check tthe CPU socket first for bent pins. Assuming they are all alright install the CPU/heatsink/fan including thermal paste, the buzzer, memory and PSU and then try and POST and note what beeps it emits.
-
this is with the motherboard out of the case?
-
Yes for now just for testing purposes lay the motherboard on a piece of cardboard or something else non conductive. DONT FORGET ANTI STATIC PRECAUTIONS!
-
okay thats what i have done but stiil exactly the same and no beeps. for what its worth i got one of these http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=150481595385&ssPageName=STRK:MEWNX:IT . dont know if they are any good but when its in the board it doesnt post anything. According to the guide 1st post should be, 00 : code copying to specific areas is done passing control to INT 19 bootloader next.
01 : processer test 1, processor status verification. Test the followingprocessor status flags carry,zero,
sign, overflow
It doesnt even post 00, and the card works as i tried it in another pc
-
Not being funny but you have installed it in a PCI slot not a PCIE haven't you? Assuming that is the case I would say remove the card for now and try removing the memory and see what happens when you try and POST.
-
PSU = new should be good
motherboard = tested good
graphics card = tested good
RAM = should give beeps when not in means it is the CPU
-
thanx again for both replies. It was in a PCI slot, removed card and memory and tried again. still the same. No beeps, just a faint click from theea. will go to a local pc shop and see if they have a processor they can try in it. fingers x'ed
-
Well it's definitely looking like the processor is the problem. Good luck.
-
Hi, cpu was found to be faulty and recieved a replacement today from ebuyer. I must say Ebuyer have been absolutely spot on, paid for collection and delivery on all items and fast turnaround of replacement items. They never even charged me for the collection/delivery costs on the motherboard which they found to be OK. Anywayz CPU installed and up and running again. many thanx for the input and help from everyone
-
I'm glad to hear that everything turned out alright in the end. Ebuyer is very good on the returns side of things nowadays and I really can't knock the business I have done with them. When they first started they were a bit hit and miss with the returns but since then I really don't think they can be faulted.
