9700 Pro problem

[iamfried]

I am wondering what the problem with my card might be. I have an A7N8X board with a 2500+ barton, 1GB ram (366MHz), the mentioned 9700 Pro, 80GB hard drive, dvd burner, and a cdrom.
When I boot, sometimes it won't boot and responds that I have not plugged in the power cord for the video card. If I keep trying to boot, it will eventually boot and then works fine until the next time I turn off the computer.
Other than not ever turning off the computer, do you guys have any ideas what I can do to try to fix this problem.
I was thinking that it was a temperature issue on the card b/c it is hot to the touch after it has been on, but it happened yesterday after it was turned off for more than a day.
My other idea is that my power supply needs to be bigger. I have a 350W supply but I wanted to get other opinions on how big of a power supply others were using affectively before I drop $100 on a 460W supply.
Thank you for any help you can provide on what may be wrong.
And btw, it is not overclocked (it used to be until I noticed problems) so that isn't the problem...

i think it's definitly a power supply problem, but before you buy another one change the power cord to the video card, don't share it with the hard drive, share it with the power to the cd roms try this first!

cow iscorrect, best of all is to use a molex that doesn't have anything else running on the line.

Yeah my PC takes like 45 seconds to show a BIOS screen after I installed a 9700NP. When I first hit the power button it get's about eight beeps and then 45 seconds later it boots. I thought it was a power issue so I unplugged all devices(Floppy , DVD, CDR-W and extra fans) and still had same problem. I'm using a Antec True Power 330.
