DirectX 9.0b for me. I don't know about sound drivers. My dad usaully maintains this PC.
BTW, I'm having problems with my PC back in my room, I usually use it to map for HL1 and photo-editing 'n stuff. I decided to hook up my PC to my PC, with 150 watts of pure sound power. I think that might've strained my power-supply altough it didn't happent until I toggled on UDMA for my PC with a XP tweaking program called X-Stetup.
The problem is that now that I try to login, it say; "loadin your settings" and then I hear the hardrive activity noise and then it reboots. I've tryed booting with Safe Mode and Last known good conguration and it still won't work.
Please help!
