GA-P55-UD6 rev 1.0 - gone the way of the Dodo?

[ncorp]

Hi,

1st post, in an attempt to salvage my PC.

PC has worked flawlessly since November 2009, however last Saturday morning, it refused to fire up.  Upon further investigation, a house fuse had blown, this was replaced, but the PC appears to have suffered a catastrophic failure.

When switching the power on i.e. switching the power switch on PSU to ON, the ACPI LED S4/5 is red immediately. The power button on the motherboard, is blue. No other lights are seen.

If I press the power button on the front of the PC, there is a slight squeak and the MD1 LED goes green and the MD2 LED goes yellow. ACPI LED S3 is orange and S4/5 red LED goes out. The power button on the motherboard is still blue and no other lights are seen.

No peripherals are attached at all. Only memory is plugged into slots 1 and 4.

All buttons on the motherboard have been pressed (power, reset and CMOS_SW) and the battery has been taken out and put back in after 5 mins. However, none of this has made any difference and the PC does not fire up at all.

Have logged a ticket (on Monday) with the Benelux Tech Supp, but having contacted them today, their Tech Supp guy is on a course and I'm left dangling...

Going on what is said in the manual, it looked as though the issue was with the memory, (MD2 being seen as yellow), however, having bought new RAM and replaced it, the exact same sequence of events occur.

MB = GA-P55-UD6 (rev 1.0)
CPU = i7-860
RAM = DDR3 2x2Gb @ 1333
GPU = GE Force GTX260
PSU = 650W
BIOS = As is was when it came, believe it to be F3, but don't know for sure, and I'd wager the boot sequence isn't getting as far as the BIOS...

Any assistance will be gratefully received as I can't find any similar scenarios to reference.

Cheers,
Ken.

Hi and welcome to the Gigabyte Forum Ken.

Perhaps you can clear up a question for me first. Was the computer actually running at the time the fuse in the house blew ?

Many thanks for the welcome.

The PC was not running at the time, we had returned from walking the dog... 

It is my suspicion that by turning the PC on, the house fuse blew.  I omitted to say in the original post that when I took the side off the PC to have a peek inside, no LEDs at all could be seen when switching the power on, which pointed (at the time) to the PSU being at fault.

I have replaced the PSU, and now have the results as outlined in original post.

I guess I'm querying whether or not the board is 'dead' and if there is a known work-a-round to resolve the problem.  Do the sequence of the LEDs signify a particular issue...?

I'm also very keen to find out if Gigabyte would welcome the return of the currently defunct board and replace it. Originally purchased in November 2009.

And finally, I'm wondering if the CPU is still alive, or is it also needing replaced...

Many thanks for your assistance.

Cheers,
Ken.

With the extra information I would say it is quite likely that the board or CPU or both have blown. That is often the trouble when a PSU blows it takes out other components as well. This is why we always try anmd get people to purchase a good quality PSU rather than some cheapo rubbish that wehn it goes takes half their system with it.

Gigabyte warranties their motherboards for three years normally from the date of manufacture so you can always enquire about an RMA repair. Same with the Intel chips if they are the retail version.

Hi,

Many thanks for the feedback.

Would just like to briefly mention that the PSU that went bang (albeit with no noise or smoke, or smell) was a SilverStone DA850 which has/had the following-->

"Over current protection, Over power protection, Over voltage protection and Short circuit protection."

The unit couldn't be described as cheap, however, obviously something went askew...

I'll see if I can get any positive murmurings from the Benelux support guy and hope that the GPU remains intact, not to mention the system and data disks.

Many thanks once again.

Cheers,
Ken.
