FOUR hard drives
TWO optical drives
and a top of the line video card
and you want to put a 430W on that? Excuse me if I may pull a Dane Cook but "ARE YOU OUT OF YOUR FREAKIN MIND?"
In all honesty, a good power source is vital to every new computer being built and I've seen SO MANY people put ****** PSUs in their computers and have them 1) Huge crashing problems or 2) Blown up PSUs. I recently built a new comp for a friend with a no-name 500W PSU. He had 4400 X2,7800GT, 2 Optical drives, 1 IDE hard drive. It blew up within 48hrs of me assembling it.
Granted I run an overclocked 3000 Athlon64/DFI/6600GT/2 SATA/1 Optical but I still built with a 520 OCZ and was glad I didn't skimp as I've had no crashing problems like you said.
Try a different, more powerful PSU and see if it remedies your problems. Crashing during games is usually power problems or overheating, as it puts more load on your system as a whole than memtest or prime95 since neither of those use the graphics card.
