Windows XP Home shuts down within minutes of starting any 3D game (eg Doom 3). The system will not start again unless unplugged for several minutes. There is no error message and no logged messages, nor any error messages when it starts up again.
This is a brand new computer and as I suspected defective components I have replaced the following with new components (one at a time):
- power supply
- Video card
I have also completely reinstalled Windows XP with all service packs and updates before replacing the RAM/ Video/ Mainboard.
All that is left is the CPU. This computer has cost me double as I have had to purchase all new components to replace the ones I suspected of being defective.
Your help would be most appreciated.
