Wierd problem - spec of PC below:
P4 3GHz, 1GB RAM, Gigabyte GA-8PENXP Mainboard, 2 x EIDE Drives, 1 x SATA drive, Leadtek A380 5950 Graphics card, Audigy 2 soundboard.
OS - XP Professional SP1.
In certain games, e.g. Painkiller demo the PC will just shut itself down ( that is power off ) almost as soon as the game starts. Don't really put this down to heat as other games ( FarCry ) runs fine for hours.
Tried various driver levels - from current working back to some earlier versions of Nvidia driver sets but to no avail. It's not a showstopper but it's now beginning to bug me, fair enough a crash to desktop but a full shutdown of the PC seems really odd.
Any ideas, solutuions gratefully received.
