Windows – Certain games seem to cause the machine to power off

crashwindows 7

I'm running Windows 7 Ultimate 64-bit (RTM) on a box with the following specifications:

  • Core 2 Duo E6600 (2.4 GHz)
  • 4 GB DDR2 667 RAM
  • Built-in Realtek 888 audio
  • ATI Radeon 4890 graphics card
  • Shuttle SD39P2 with 450 watt Shuttle PC-55 power supply
  • 320 GB Western Digital 7200 RPM hard drive

Whenever I fire up the Sims 3 or Trine on my machine, each game seems to crash my machine at the same point. I don't get a BSOD or crash to desktop with an error; the entire system just turns completely off (and won't turn back on again unless the master power switch on the back of the case is flipped). I can play other games without any issues.

I'm using the very latest drivers for my sound and graphics as of 2009-08-23. Any ideas?

It sounds like a hardware problem: overheating or insufficient power supply. I think the ATI Radeon 4890 requires a minimum of 500 W for a power supply. Check the specifications here, 500 W recommended.
