I've got a big problem with my PC. The motherboard and processor are getting old, and I recently bought a powerful fan to take care of the regular overheating problems which I thought were the cause of the crashes and freezes I was experiencing. But it seems to be something else thats affecting my system. Whenever I copy-paste into Paint my system freezes. It also freezes on some high content macromedia flash websites. Particularly annoying is the crashes I get when running iTunes when I'm simply browsing through my music library or copying some music onto my iPod and the mouse stops moving and the computer has to be restarted. I've also experienced crashes on such a regularity when playing GTA:SA or FM2005, that I can't play them anymore because the system has to be reset within 30 mins of playing these games (more often than not losing my saves). Freezes also occur in work related programs such as Photoshop, Word and Outlook. To me, this sounds like a problem with either a) the RAM b ) the graphics chipset c) the processor, or d) the motherboard. But I'm not a tech head and don't really know the signs to look out for. My system temp is variable around 100 degC, so I don't think heat is the problem. If someone can advise me I would be very grateful.

100 degrees Celsius is above the specs for your processor. Maximum die temperature for the CPU is 90 degs. Celsius. You can find a good, free memory testing utility on the Internet. It is called memtest86. Rule #1 Good computers don't go down. Rule #2 There is no such thing as a good computer.

Yes, 100 C is too high. I had the EXACT same symptoms on a laptop I have. The problem ended up being the RAM sockets that hold the RAM in. This also caused the laptop to be very warm. If you use 2 sticks of RAM, take 1 out and see if the problem still persists. If so, take that stick out, and put the other module into the opposite slot. If God has to teach someone a lesson more than once for them to learn it, it just shows how stubborn they are.
