I have been having some video issues with a 32Meg Hercules Prophet PCI card, where the video works fine for a bit, and then randomly screws up during games and graphics demos.

I thought it might have been a IRQ conflict, so I switched around the card until it ws only sharing IRQs with PCI steering (before it had 3 other shares!) but still the same issues.

My question is, can an insufficient power supply cause video problems ?? I noticed the other day that my PS is 200W, and read that the recommend PS for the video card is 250-300W. Would a new PS fix the problem ?
