Symptom:
The system stays stable for hours in TF2, but within minutes of getting back on the desktop, it will hard reboots.
What I've tested so far, without success:
- Disconnected the two mechanical drives
- Left out 1 of the RAM sticks at a time
- Swapped out PSU for an older unit
- Unplugged front panel USB and sound cables
- Uninstalled the ATI driver
- Reinstalled the ATI driver
- Booted into Ubuntu LiveUSB
- Unchecked "Automatically restart" in System Properties -> Startup and Recovery
- Reinstalled Win 7
It does NOT reboot if I go into safe mode.
It also does NOT reboot if I take out the 5870 and use the onboard video.
I noticed the card's cooler is quite hot to the touch - but that doesn't explain why it's fine in TF2. Fan seems to be doing its job: if I unplug the PCI-E power cables from the card and boot up the machine, the fan will spin at full speed - very loud and a lot of air.
Drivers are up to date.
Video card has never been overclocked.
I'm running out of ideas and am getting close to writing off the card
Specs:
i5-2500K

2x WD Caviar Blue 640GB
In Win Dragon Slayer
