Judging by what i see in this report. Im guessing it's not the power issue.

[recovering disk SPACE - old attachment deleted by admin]In my Dxdiag im seeing my display DRIVER subcategory.

The main driver said
Main Driver: nvd3dumx.dll,nvwgf2umx.dll,nvwgf2
Version 8.17.12.6099
Date 10/16/2010 1:55:00 PM
WHQL Logo'd: n/a
DDU Version: 10
Driver Model: WDDM 1.1WHQL Logo'd: n/a

after using Driver Agent and reinstall the graphics driver and able to fix only 1 out of my 11 bad drivers I'm awaiting if the problem still occurs.


In other news now says WHQL Logo'd: Yes
Hey

I recently had the same problem with my XFX Radeon 5770.  Read all the online 'issues' with it, tried all posted workarounds that helped anyone,
then based on that assumed it was the vid card too.  I opened ticket with xfx help desk to pursue the RMA process. 

They helped me troubleshoot it.  It wasn't the card.    The first tech said not the card, INSTALL this program and that to get my temps, try new higher rated psu etc....
The 2nd tech was bang on, he suspect memory controller errors.   I had latest version of MemTest 86 ready to go - This led to the problem, my ram.

Pls download the most recent version of MemTest86.    Let it run for at least an hour or so.
Any errors with the ram or 'correctable' memory controller errors'  ?

Oddly I thought that (memtest) was already suggested, but I must be thinking of another thread. Definitely worth a shot to use memtest if they continue to have problems (and my guess is they will).

Memtest86 saved my bacon. 

There was similar error caused by earlier ati driver, but that was fixed awhile ago. 

Did this start suddenly without reason or following hardware change or overclocking tweak ? 

Another thought, there's other driver issues on the pc ?

I will consider trying Memtest. But a funny story about my Ram is that i have 4 rams cards in my 4 slots but my computer only detects 3 ram cards thus i have 3 gigs of ram. It must be the motherboard's problem which cannot be fixed. The card works but the card in that slot does not.

My drivers have been tested with Driver agent. Found out i have 11 bad drivers and 57 good drivers. Someone gave me the exact files i needed i tried to install those drivers.

About hardware changes, I did  upgrade my video card, cpu, psu, heat sink, and added more ram which the ram had problems detecting. Quote from: Bunbotman on December 01, 2010, 08:12:56 PM
