Gigabyte Radeon 6670 DDR3 Major Problems

[Theonetruebro]

I've been having this problem for about two weeks now and just now gave up and took my video card out. I am at a loss for as what to do. It started about a month ago, a month after getting it (I've had it for 2) My screen would flicker while gaming if my graphics were too high. I ignored it, and just lowered my settings thinking it had something to do with my monitor. Now, about a week ago I started up on wow and started getting crashes. I would get a VPU Recovered error, and be able to continue playing, and then sometimes it would just crash and require me to reboot. It got increasingly worse until I could only go for 15min before it crashing. I now am running on my onboard video card, which is absolutely horrible, so any suggestions would be greatly appreciated.

What I've tried
-update drivers
-Reinstalled CCC
-Reinstalled Windows
-"under"clocked the GPU
-Lowered all settings on all games + on CCC

Here are my dxdiag results. Keep in mind, my video card as of this writing is NOT CONNECTED, not even physically. It's a GIGABYTE RADEON HD 6670 SERIES 1GB DDR3. Should be compatible, conbsidering it worked perfectly for about a month

it could be just your psu not supplying the required amount of power properly.

 

[Theonetruebro]

I have a 500w PSU

 

[TheBigTroll]

brand?

also, check the hard drive and the ram just in case

 

[Theonetruebro]

TITANPOWER
ATX-500ps

And my hard drives are both fine, ran check disks on both of them plus completely reinstalled windows. What do you mean by check ram?

 

[TheBigTroll]

yeah bad psu but it shouldnt be the problem. did you ask the manufacturer yet?

 

[Theonetruebro]

No, its closed pretty much whenever I can call them. Ill try that, however i've looked online for their troubleshooting and nothing helped. I was thinking of any BIOS changes or anything I could try.

 

[TheBigTroll]

im pretty sure you can. try putting the card in and see if it works. not like its going to damage anything
