Is my video card beyond repair?

About a week ago my PC started to freeze during games. The screen would either go completely black, or weird red vertical lines and dots would show up on the screen. The event viewer showed this message:

Event ID 18, WHEA-Logger

A fatal hardware error has occurred.

Reported by component: Processor Core
Error Source: Machine Check Exception
Error Type: Bus/Interconnect Error
Processor APIC ID: 2

A few days later, it started happening more and more often, and not just while playing games, until it wouldn't even boot to windows. I managed to boot in safe mode, uninstalled the video driver with an AMD uninstall tool, rebooted normally and the PC stopped crashing.
The problem is, it only works with the generic windows drivers. As soon as I install ANY AMD driver, even older ones that worked before, the PC glitches. I reinstalled Windows 8(x64), I even installed Windows 7(x64) on a separate partition, and the same thing happens.

I do plan to buy another video card relatively soon, but I was wondering if there's anything I can do to fix my current card.

My PC:
Video Card: SAPPHIRE HD 7770 GHz Edition 1GB GDDR5
Processor: Intel core 2 quad Q8300 @2.5GHz
Motherboard: Asus P5P41T LE
Power Supply: Raidmax KY-600ATX 500W
Memory: 6GB DDR3 1333MHz
 
Solution
your video card is beyond repair, as with any GPU issue, they are almost impossible to repair as to try and pinpoint the issue is like a needle in a haystack. You will have to get another GPU.
i would check the card in another build, because it could be that the pci-e bus has gone bad on the motherboard, rather than the card going bad.
reason i think this is your motherboard is getting on and is a fair bit older than the 7770. so may be suffering with a bad power phase to the pci-e bus.
 


+1 for this. Try underclocking the GPU with AMD Overdrive in Catalyst Control Center and see if it stabilizes at all. If it does, then it could be a power issue when under load.

If you need to replace the PSU on a budget. XFX and Rosewill Hive are good options with reasonable cost.

Also, if you uninstalled the driver and the crashing stopped it could be driver corruption. have you tried reinstalling the driver yet?

@HEXiT:
Thanks, 'll try to find another PC to test the video card on.

@maddogfargo:
Yes, I tried every driver from 13.4 (on Windows 7) to the latest beta driver(14.4). And as soon as the driver installs the PC glitches. So the pc doesn't work at all with amd drivers installed, and amd overdrive doesn't work without them, so I can't use it.
