how do you do that?
I'm sorry to hijack the thread but that's almost the exact problem I'm having. Firstly, my specs:

Phenom 2 965 @ 3.7GHz
MSI 790FX-GD70
2GB OCZ SLI DDR2000 RAM
Radeon 4670 OR GeForce GTX260 (tried both)
AOpen (rebranded FSP) 700w quad 15a 12v rail

I can crunch for weeks without a single issue, but as soon as I add ANY 3D load, be it a game, Furmark, 3DMark or GPUGrid the PC goes into a "suspended" mode, exactly what it is like if you hold in the restart button. I hear the DVD and hard drive power cycle and the screen switches off. If I hold the power button in for five seconds the power LED on the case continues to flash and pressing the power button doesn't do a THING. It remains dead until I pull the plug and allow the caps to drain. Certain things such as the flashing LED tell me it's motherboard but everything else says PSU. I have tried two cards, one stick of RAM at a time, reset the BIOS, reseated the CPU... Everything except a difference board or PSU as I don't have either. The PSU was "abused" several years back, I benched an E8600 under LN2 and dual 4870x2s as well as dual 9800GX2s. Where would you say the problem lies? At the moment I don't have access to replacements for either and can't afford to buy the wrong component.
