Help with CPU cooling for a newb
Hello everyone, I'm new to this forum and have come because my computer has been giving me some problems that I think may be cooling related. First off, how can you tell if overheating is a problem with your computer freezing up, shutting down, etc. One day I was using the computer and it just shut down, and when I turned it back on the light around the power button was not lit up in the functioning mode, so I looked inside and the heatsink was pretty heated up. I left it for awhile and tried it again and it was fine again, so my only thought would be a heating problem. Most recently the computer froze, so I shut it off and waited awhile and turned it back on and it wasn't responding again, so today I unplugged everything and cleaned it all up and noticed that there was a lot of dust and stuff on the fan of my video card, I cleaned that up and turned it all back on and it is working now. Now I love my computer a lot, and while I'm not fully versed in all the nuances of computers I've got a pretty good knowledge realm of it all. Any pointers to start with?
