Okay so I built this PC around October last year, it was my first experience building one, but I had a lot of help from an experienced friend. It had been running fine, but recently it has been randomly restarting. It used to do it only in winamp, so I thought it was a soundcard problem, so i upgraded my card but that still didn't help, so then I switched over to using foobar2000, it still happens. The restarts appeared to be happening less but it still happens. It has restarted in the following situations: playing music, surfing the internet, playing hitman 3, and just deleting and avi. I dont know what to do at this point. I ran memtest86 over night, 29 passes so I know that my ram isnt the problem. Does anyone have any suggestions? My specs are: Intel P4 2.4 1 gig RAM ASUS Mobo Geforce FX 5600 Audigy 2 ZS 120gig HDD Floppy DVD rom DVD-RW 480watt Antec True Blue PSU Thanks in advance.
