It locked up. How long since you cleaned the heatsinks and are you able to see if the heatsinks are in place?
HI, when I startup my laptop with xp, the found new hardware wizard starts. I have not installed any hardware, but if i let the wizard run, it says it can't install as there is no software.On my systems info, under other devices there is ATICDSDr, with a yellow !,. Also, after a few minutes running my laptop, a 2 tone double audio signal sounds, and my computer freezes, with sometimes my display wavering slightly. Any suggestions? thankyou
