Odd Reboot Problem

[Digamma]

I have encountered an odd problem. Whenever I start CS:S it seems to work fine but when I click options, my computer reboots. This also happens with HL2: DM also, but strangely not HL2. I have a similar problem with CS 1.6 except it reboots right when it start the program. Anyone know what this is and how to fix it?

Try this:
steam://runsafe/240 (CS:S)
steam://runsafe/320 (HL2DM)

Try this:
steam://validate/220 (CS:S)
steam://validate/320 (HL2DM)

Best bet is to set your PC not to hard reboot on errors, the alt-tab out and see if you get an error message. Follow the instructions at the top of here
