Thanks, I checked out that post. I have a feeling that I may have gotten a somewhat faulty power supply. Supposedly my card should run fine on a 400 watt variety. Reading the reviews on my power supply, it's good, "if you get a good one". I'm thinking there might be faulty workmanship involved. But typically you get what you paid for, and it was half the price of other power supplies of the same wattage. I can't afford the cash for better power supply until next paycheck. This is gonna suck if I have to wait like 3 weeks to play SH4 again.
