Ok. I have a P4R800-VM asus mobo (ATI chipset). When I put any AGP card in my computer, the computer starts to freeze up during any intense graphics apps, like games :(. When I use the onboard video, games run fine. At first I thought it was my mobo, but now I find that I've been running this thing on a 300 watt PSU. The 12 volt rail delivers 11 amps. Is that enough? Could this be my problem?

"300 watt PSU. The 12 volt rail delivers 11 amps. Is that enough?"

Not even close! At the very least, you should have 16A on the +12v...18A or more is recommended

Ok... Everyone I've talked to said that a 300Watt power supply is minimum but enough for a P4. Also, my main question isn't whether 300Watts is enough or it isn't. The question is, is the power supply the reason my computer freezes up when I play games with an AGP card.

It's a good enough reason and the best place to start. DOn't look for an "el cheapo" 500 watt to help either. Plan on spending at least $50 for a brand name, quality PSU or you will be back here soon.

I still think it's my mobo but I will try putting in a different PSU. I find the "Not even close!" remark very funny because it's obvious you're trying to sell me that PSU u linked. 300 Watts is minimum for a P4 and I'm pretty sure minimum implies at least "close enough".
