Hi again: I just built a new PC, except for the CPU, which is used. The problem is that when I'm running some intensive programs like FPS games and stuff, the PC just shuts down. Now, I guess it could be either the PSU or processor. But I'm leaning more towards the processor. It would be strange though, because that CPU was working fine on my other computer. When I checked the temps after playing Serious Sam for 30 minutes, the CPU was reading 66 Celsius, or 150 Farenheit. Is this within the safe range? So, anyone has any ideas why is this thing turning off on me? Thanks for your time . Specs: AsRock mobo (integrated everything) 512 RAM (Generic) AMD Athlon XP 2600+ (used) 400 W PSU (Dont remeber brand) WinXP Pro
That is a bit on the warm side, so I would look at the case cooling first and make sure the cables and wires are tidy, then look at a better heatsink. Also, take into account that the readings may not be the most accurate. If it's not being read from the on-die sensor, it's much more likely to be inaccurate.
Also having a heatsink thats old or more of a generic brand can sometimes mean its not very smooth and less contact is made with the CPU. You can lap it or add some quality thermal blob.
I'll have to keep my eyes peeled for a lapping guide as I browse around, because I know they're out there.
you take around 300 600 and around 1200 grit pieces of sand paper or just one sheet of extremely fine grit. Doesnt matter but moving from fine to a VERY VERY fine paper is faster, wet sand the bottom of the heatsink with the course, moving to the fine paper making a smooth, even surface for the CPU to hit the heatsink, making more touching surface area and better heat dissipation
To add/clarify: Lapping is a means of smoothing out the base of the heatsink. Instead of taking the very fine sandpaper and rubbing it on the heatsink, you want to lay the sandpaper down on a flat surface, add a few drops of water (making it a 'wet sand' to avoid having sawdust) and place the heatsink on the sandpaper. Now you just make circular motions with the heatsink. It'll take some time, but you'll have a pretty bling-bling shiny surface. Some people use polish as well (which can be found at auto parts stores), but you don't have to.
