My PC freezes randomly and requires a hard boot. I thought that perhaps the PC needed cleaning so yesterday I cleaned it very well, (compressed air) even cleaned and changed thermal paste. CPU typically runs at approx. 50°C - 60°C. I didn't think that this was too hot but decided to clean the PC anyway.
Today the PC ran for 4-5 hrs. and no problem then it froze. After reboot it ran for approx. 10 mins. and then froze again. Rebooted and approx.10 min. once more. The next time I decided to see how long it would run if I put it under load. I played FLUX and Zuma until I got tired of playing and no problem. I'm probably online more than not, but it always freezes when I'm online?
So if the problem is not heat, could it be the PSU ?, or what else could cause this? Appreciate some input. overthehill
