420 watt power
Athlon xp 2600
radeon 9800 pro
Roughly a year ago I bought a Radeon 9800 pro to replace my old ti4200. It worked perfectly for about two months then it began to (every once in a while) freeze while playing games and force me to reboot. I didn't think much of it at the time, but it started to get worse over the next couple of weeks until it got to the point where every time I started a graphics-intensive game it froze immediately. An audible "click" noise similar to the click when you first press the power button always happened seconds before it froze.
So I sent it back to ATI and recieved a new one, a couple months ago, and it had been working fine again. Then all of a sudden, eariler this week, it froze unexpectedly. Now the entire cycle is starting to happen again: it freezes with that telltale "click" about once an hour. It's getting worse and is going to force me to sell it or send it back again.
I've tried all sorts of Catalyst versions along with other drivers-- same thing. Every trace of the Nvidia drivers has been removed, of course, that was the first thing I checked. If anyone has ever seen this before or has any idea what is going on here, I'd love to hear from them.
