Hi all, My dad's computer is having a bit of an issue at the moment. Here's the details. When he boots the pc, all the fans spool up to normal levels, the bios launch opens and then the Win XP loading screen opens and suddenly, the entire system shuts off. We recently took the heat sink off the PC to clean it out and that was pretty event less, however, I'm wondering if something wasn't damaged by doing this because before we took it off, the PC booted and functioned normally. He also has been having issues with Front Lines: Fuels of War. He initially installed it and played a few missions with no issues and then it stopped getting past the launch screen (odd). He has an Intel Q8200 CPU, GTX260 GPU, 4GB RAM and a P5QPL-AM Mobo. Any ideas? I thought either the motherboard is damaged (yet I can get into the bios function and play around) or perhaps the power supply (Thermaltake LitePower 430) is dying? *EDIT* I just noticed while having a look, it stays 'on' for less and less time each boot. Example, will boot to Win XP load screen, next time I can get into BIOS only, then the next time, I get into the screen just before BIOS. Perhaps I haven't applied enough thermal paste or something is overheating??
