I've had my 9700 pro for about 6 months now. The past few weeks, I haven't had too much time for games, but when i've played, things have been ok (except for crashes in d3 which were fixed with the 4.9beta's). Anyway, I installed a wireless card in my system last week, and that nite, i started getting artifacting in windows. I would open a firefox, and the screen would go fuzzy, with lines through everything. I haven't had time to check if games are affected, so i can't be sure. I'm hoping its my psu, as its 300w and I'm running an athlon xp, two hard drives, the video card, a dvd burner and a sound card, along with my modem and various usb connections. Could it be dying though? Is this a common problem with 9700's? Anything I should check before I upgrade to a new psu?
