It's possible it's power related. I've got a seasonic 350 watt supply and have gutted the system so only the mobo, hard drive, and card are running right now, but I'm still having the same glitches. I can get rid of them if I drop the resolution down to <1280x1024 though. Not so good since my 2001fp likes 16x12 much better. Also, the fan on the card never spins down. I've got the case open with an extra fan blowing onto the card so it's at 52C idle, and the fan is still going full tilt. I'll pick up another power supply from work tomorrow and plug that into the molex connectors to see if that fixes things. If so, I guess a psu upgrade is in order....but I'm still concerned about the fan never slowing down and the card idleing at 60 if there's not another fan blowing on it.
