Troubleshooting: Random power failure and reboots

post #1 of 5
Thread Starter 
I'm trying to help my friend out with his PC.
He claims it is randomly loosing video, crashing, losing power, etc.....


The rough specs AFAIK:
CPU 2500k stock clocked
Motherboard Asrock Z68 Extreme3 Gen3
GPU Sapphire 6950 toxic edition
PSU Corsair 850watt (I cannot remember the exact model)
RAM 2x4gb (can't remember model)
Case Aerocool Strike-X ST Black Edition


So far I've seen it suddenly reboot when logging into windows at the welcome screen and I have seen it suddenly turn all the way off.
I suspect it is an issue with the PSU, motherboard, power switch, something grounding out the motherboard, or possibly the way the fans are set up inside the case (it has an unconventional integrated fan controller).
Thermals seem fine.
I ran a simultaneous stress test for over 2 hours.
Prime95 (large FFTs) and Furmark.
CPU was at 55C and the GPU was at 87C (only 46% fan speed...weird right?).

The GPU is OOW but the motherboard and PSU are still in warranty.
He said it was losing video so he swapped the GPU with another system that had a HD 7770 and an AMD BE945.
He also put some fresh Prolimatech PK1 thermal paste on the GPU.
He stated that neither PC then had a problem.

I could put a different PSU in the system to test it out....but that would take down one of my PCs for a few days.
Does anyone have any easier/faster methods for isolating the issue?

Yeah.
It complains about lacking an ATAPI CDROM..........which is fine as it is disconnected.
It also says this "The kernel power manager has initiated a shutdown transition."

I finally got the PC to replicate the issue.
I had the PC on for 2 days straight and it was fine.
I played dead island @max settings for 10 minutes....it was fine.
I played left 4 dead @max setting for 90 seconds........power failure, PC attempts to restart, power failure again, I attempt to turn it on power failure AGAIN (even faster this time).

I put in a spaghetti Antec EA650 for testing.
I ran L4D for 30 minutes @max settings without issue.
I think it's the PSU.

Does anyone know the phone number for Corsair PSU RMA?

Set up the RMA with Corsair.

They won't pay for the UPS shipping label on the first RMA.......only the 2nd one on.
They also said they wanted the modular cables with the PSU as they were going to give a new PSU back as part of the RMA.

When you go online to set up an RMA it takes 10 minutes to make the account and 2 minutes to make the RMA.
They don't ask for a serial number or a receipt.
They tell you where to mail it to but they don't tell you what you need to send in (modular cables in this instance) and they don't tell you how long the RMA process will take.

After I set up the RMA they gave me the phone number to call if I had questions...which I did....so I did.
