The computer consistently crashes and reboots within 5 minutes to an hour of gameplay - doesn't matter what game, even Portal 2 will do it. The error above is one of many I've gotten since first getting the computer several months ago - it's an Artesian build, so I guess I'm not surprised given what went down there. Nothing is overclocked; everything should be at factory settings. Local tech support is stumped, as stress testing produces no errors and internal temperatures all read fine. Could be a faulty part, but it's difficult to check because it can take a while to produce a crash. Any suggestions?

Done a fresh install of windows yet?

As a matter of fact, yes. I also updated the BIOS and chipset. No change.
