New PSU causing driver crash

[gabt]

Hey all,

I recently had an issue as described here

So I got my PSU replaced but now I'm having a problem whenever I run any 3D application that puts a load on the GPU (FurMark, 3DMark, games, etc) causing the graphics driver to crash with this error code and I'm running out of ideas on how to solve it.

Some things I've tried:
- Reseat graphics card
- Reconnected all power-related plugs
- Clean uninstall and reinstallation of graphics drivers
- Forcing PCI-e gen 3 in BIOS

Any help on this would be much appreciated!

Turns out the driver crash was throwing up the infamous TDR. I extended the TdrDelay value in the registry to hold out longer and it seems to display a pattern of coloured blocks (graphical artifacts) before blacking out and recovering. My guess is that my GTX770's VRAM's faulty =|
