Diagnosing a laptop
I know, I know, just get a new computer...
I have run my laptop into the throes of death. Coretemp regularly read in the 90s and even hit 100 quite a few times while I was beating it senseless with some audio recording programs. It started shutting down randomly a month or so ago, and gradually became less and less useable. Now it rarely stays on beyond five minutes of use. The shut down occurs whether I'm in windows or in BIOS, if i'm on battery or outlet power, regardless of temperature, regardless of the programs I am running, and whether or not I'm in safe mode. My computer is also virus free according to a number of free malware/virus scanners. I always knew its day would come, but I had hoped to get a new comp sometime before it died so I could retire it to a homework machine. Obviously, I failed, but some crazy part of me still thinks I can fix it.
My first question is: what would I most likely have ruined based on the above description. I suspect processor based on readings from coretemp, but others have suggested the mobo. Could it be power supply? Could be all three I suppose. I know the hard drive is fine, as I swapped it into the laptop i'm using now, and the ram is fine.
My second question is: even if I figure out which component is fried, will I be able to do anything about it?
