Possible GA-MA770T-UD3 problem

[jeggsy]

Just to let you know, I have spoke to the company that I bought the parts from and they have agreed to RMA the motherboard and CPU.

I have mentioned about the bios revisions/Athlon 265 support when I raised the RMA request.

I'll keep you posted of any news.

This forum and helpfulnes is just one of the reason I always use Gigabyte motherboards in any system build. Great products !

Typing this out on a GA-EP45-UD3P now as I type ! !

[jeggsy]

Right guys.... latest news.

Aparantly the motherboard & CPU were fine when the company tested them after I had them RMA'ed. They have updated the bios to the latest F8 relase as well.

In the mean time I have sourced another new Antec 550w PSU of the same type.

Put it all in the case this evening... Powered the system up and I get the same thing as before with no boot    

Case fans, PSU fans, CPU fans spin up. Hard drives and DVD drives power up but still no boot from the system. There's no beeps and the monitor does not kick-in.


HELP ! !

I have found that quite a lot of these companies say they have tested the components when in actual fact they haven't . Some don't even have the fascilities but just use it as a ploy to get rid of the customer. I don't know if this is applicable in your case but it does go on.

 It might be worth asking the retailer what hardware they tested it with and see if that helps at all.

I know it is a pain but can you take it out of the case again and do the most basics of setups.

Just spoke to the company and they have assured me it was tested fine. They said it was definetly working as they upgraded the bios as well.

They sent me a list of the components they tested with:-

780w Tagan PSU.
EVGA GTX460 VGA.
1600Mhz Corsair (Dual Channel)

I'm going to try a different VGA card and I have some different memory just as a test.

hi if you get the same result after you change the graphics card your next step would be memory

I would suggest removing one stick of ram and trying it then change the stick of ram for the other and trying it it could just be a faulty stick of memory


hope this helps

Right guys.... progress 

Managed to get my hands on some old ATI Radeon X1300 and Geforce 6200 PCE-E VGA cards to try. Thought as their older, less power draw in case of it being a PSU issue. Tried these with no succses.

Also managed to find some more DDR3 memory. Again, no succses.

Cleared the bios etc and still no go.

Looking at the PC at this stage, the only things connected are 1 stick memory, VGA card, case power connection and PSU.

Removed case power connection, shorted it using a spare jumper and beep, system POSTS.... Bios screen.... looking for boot device !       

Now the only problem being is trying to sort out why the case power switch doesn't wotk with this motherboard.

[Dark Mantis]

Yes we should have covered that really. It could well be that the switch is just crap and not working electrically. Still it's a nice easy fix and not expensive either. Just double check that you have got it plugged into the correct place in the Front Panel Connector on the motherboard.

Spoke too soon.... it won't POST again now.

Had it sat next to me running whilst I typed the above, rebooted and now it won't POST again.

This is getting weirder by the day !

[jeggsy]

Well I still can't get it to post.

Not changed anything on it since it booted earlier.

Tried shorting the reset pins with the PC going but that does nothing.

Really pulling my hair out with this !

[Dark Mantis]

I don't know if it will help but you can try this. It will overwrite the Main BIOS with the Backup BIOS.

You can kick in the backup BIOS by shutting down the PSU from the wall, then hold down your case power button in and then turn on the power supply button, a few seconds later the board will start, shut off the power supply then.   

Then you can turn on the power supply again and power up the board normally and DualBIOS will kick in.

[evilferret]

Sounds like my issue, though mine turned out to be a combo PSU and the NB heatsink.

Link with my issue.

Not sure if I got the PSU bad or the something caused it to short but it wasn't obvious till I swapped PSU's. Couldn't get into bios. Video card only worked on the 2nd PCI-E card, ethernet was down.

Also try the video card in the 2nd PCI-E slot.

Good luck on your comp though.

[Dark Mantis]

Yes it is suprising how many problems are eventually laid at the feet of PSUs.

Right guys progress report

On Christmas eve I got playing with the system and took the motherboard out of the case. Put the motherboard on the cardboard box it came in with just the memory and VGA card. Shorted the power jumpers and it POSTED fine.

Put back in the case and no POST.

Looked at the area where the motherboard sits and nothing would be touching/fouling the motherboard etc. Swapped out the brass motherboard feet and screws for some spare ones I had. Replaced the motherboard and it POSTED fine.

Done several reboots, power off etc and still fine. Left running for an hour or so and still fine.

After all the Christmas palava, I managed to have a few spare hours with it again last night....

Started fine, inserted my Windows XP CD, done a full and proper format on the 500Gb SATA C:\, installed Windows XP. Again, done a full proper format on the other 500Gb SATA D:\. Installed .net Framework 1,2 & 3. Installed all the drivers including LAN, Chipset, VGA. The system had been fine all through this which was about 3 hours of runninng when I had more problems. It was absolutley flying !

The PC on the next reboot would not start up. I had no display but I had 4 long beeps from the BIOS. If I restarted the system that is all I got.

Googled up the 4 bios beeps and it was suggested either memory or VGA issues. I replaced the memory and VGA card with the spare I had from the other day and now I get no POST & no beeps. It's gone back to doing what it was the other day. Put the original VGA card and memory back in but still nothing.

I can't understand how it worked fine for 3 hours with no problems and then all of a sudden nothing.

This is doing my head in !

[Dark Mantis]

What happens if you remove the graphics card and try and boot?
Does the system try and then emit a beep code (assuming you have a buzzer installed) ?

[jeggsy]

If you try with no VGA card and/or no memory then you still get the same problem... all fans spin, dvd's & hard drives power up but no POST & no beeps with no display.

Tried the ATI X1300 and Geforce 6200 PCI-e's in there with the same result.

Tried the different memory in it with the same result. Even tried it in all the memory slots just in case.

Cleared the bios but this made no difference.

Nothing.... This just seems completely dead now.

In all my years of computing I've never come across anything like this.... It still amazes me that it worked so well for over 3 hours and then has just stopped again for no good reason.
