At my wits end with my PC and WoW

OK, here goes. I was having an issue with my PC shutting off at random while playing WoW, so I thought maybe it was a heating or PSU issue. SO, I decided to do an upgrade. I upgraded the motherboard to an MSI 890 FXA, the CPU to an AMD quad core 3.5 GHZ, the video card to an MSI radeon 5770, the RAM to 8 gigs, the PSU to a Corsair 750 watt, and also decided to upgrade the OS to windows 7 64 bit. For all intents and purposes, an overall new PC. Now the issue, it is STILL happening when I play World of Warcraft. It does not, however, happen when doing anything else, i.e. surfing the net, playing other games, movies, etc. I have ran Furmark for an hour and a half at max setting for the GPU, ran other tests, ran speedfan while playing (GPU temp never got above 51), tried turning down settings on the game, and it still happens. HELP!!!!!!!!!!!!!!!!!!!

the PC shuts off and restarts itself? sounds like a software issue since it does not happen on other games.

Well, what it does the monitor goes into Auto power save mode. The fans in the PC still run, and the LED light on the motherboard is still on. Now, sometimes, it will let me play for hours, sometimes minutes. I have done a complete reinstall of WoW, and it is still happening. I have tried running it in DX9 and DX11 modes, and it still happens.

Turn OFF power saver mode in your monitor settings. From what you described, your computer is not shutting off, just the monitor is going into sleep mode. I've seen that happen in other games where your mouse movements don't keep the monitor "awake".

What about your screen saver?

Updated video drivers?

Try un-installing and re-installing WoW?

Ive done a clean install, updated video card drivers, and run with little add ons (mainly DBM and Omen). When I look in the event log, it doesnt say anything, however, I dont necissarily know what I should be looking for. I just dont know what could be causing this. I wonder if there is a compatability issue somewhere?

I have, and they all come back to thinking its an overheating issue. Like I said, Ive ran speedfan while playing, the GPU never gets above 50, and the CPU never above 65

Me too! Its horribly frustrating.

OK, I checked in event viewer, and the only thing I can find for a critical error is kernel power. I have no idea what this is

Im not ruling that out, however, wouldnt it be crashing all over doing normal things as well?

Its Driver, are you using the latest driver, if i was you , go back to 10.10, best for wow!

use Driver sweeper to remove all traces of drivers from system.

1) download 10.10 from guru3d.com (undr ATI driver section)
2) Download Driver Sweeper from guru3d.com AND INSTALL
3) Uninstall ati drivers (everything including cat center)
4) boot into safe mode, run driver sweeper, check ATI and remove everything
5) MOST IMPORTANT_____REMOVE PC FROM INTERNET______MOST IMPORTANT
6) Reboot and install 10.10 drivers whilst still off internet
7) Reboot after install and test!
8) Profit!

Monitor on it's way out

He has no clue!

Not if it's only happening with one game. More likely there is a specific driver/system files issue during some portion of the WoW graphics engine that kills the card. Card dies, monitor goes out, but system can stay running.

Any other games use the same engine as WoW? I think it's a unique one myself, but would be nice to find something else aside from WoW that will cause this on this system.
