Well, the problem is further along now
Playing A Half Life 1 mod (Natural Selection) my system began to freeze up for 5 - 10 seconds (the sound looping / stuttering) then would play normally for 5 minutes before doing it again, eventually, Half Life locked up and I had to restart.
The same problem is plagging my Internet Explorer, will run well for 10-30 minutes, but if I start browsing 3-4 pages it freezes up, and locks up my system.
Any idea whats causing this ? The only things installed are games (BF2, Hl1 / 2 / mods for them, Oblivion and NFS: Carbon [uninstalled now])... I have InCD and PowerDVD, and all my drivers updated.
I only had 1 file of questionable intent (a torent that was spyware / virus checked, and a .ISO to match) and im positive it isnt that
** edit **
I went into the Device Manager in My COmputer, and found a PCI Device listed under "Other Devices" with no driver, and a ! mark beside it. Tried to auto update driver, and windows cant I.D what it is ???? It says "7600GS" under display adapters, and "Soundblaster Audigy" under "Sound, Vidoe and Game controllers" so it cant be either of these two ?
