Reboot issue on Area 51

Test another game and see if it has the same issue.

Problem solved, game had several update's, one of which fixed the problem!!  

I'd try to find something that monitors heat....rivatuner or hwmonitor for instance.

Well I spoke to soon, computer started rebooting again this morning while playing the game. I lowered the graphic settings but that didn't help. Other games aren't causing it to reboot however, my older Area 51 (Q9650, gtx260, 4 gig ram) runs this game all day long and never has a issue so it's not the game, it's the computer which isn't even 2 months old yet. I'm guessing a heat issue, anyone have any ideas?

direup, give "furmark" a try. It'll expose laden problems with your video card that other programs can't.

Also it could be a PSU problem. unplug all extraneous parts that sap the juice, ie extra HD, TV tuner, sound card, etc, and see if there's any improvement.

I've got a 1100w psu, no TV tuner installed and I don't have this issue running Crysis, Alien vs Predator, Left for Dead, ect so I don't think its a PSU issue. Wings of Prey runs fine on my older Area 51 so I'm pretty sure it's not a game issue. I just played for almost an hour and monitored temps. Here are the max temps that were recorded 

Core0 63 c, Core1 60 C, Core2 61 C, and Core3 60 C, GPU was 85 C. I never heard any of the fans really kick in during play. Sometimes the system fan jumps to warp speed but it didn't during this last game play. Anyway, 1 hour and no reboots this time. I looked at furmark but didn't see a version for Win7 64. I'll keep looking.

Thanks for the assist.

I got it, ran a standard stress test for 30 minutes, no issue, 80 C max at 1280x1024 then 30 minutes in Extreme burning mode, no issue, 84 C max same res.

Update: The test above was done with the standard version, I went back to run the Multi-Gpu stress test with Extreme burning mode and got a reboot after about 3-5 seconds. Same issue as the guy with the Nivida 295, any ideas now??

lol, I know this is going to sound stupid but try it out. disable automatic time sync for the clock in windows and try running furmark again.

Computer still reboots in the standard and extreme burning test for multi-gpu mode.

direup, I see your cards fare much bettter than mine. Mine couldn't pass either single-gpu mode or multi-gpu mode, albeit in multi-gpu mode, it reboots a lot faster, in 1-2 sec rather than the 5 sec or so in single-gpu mode.

Since your cards can be stressed to the max individually, but fail in cross-fire mode, I suspect the culprit might most likely be the driver.

direup, I just realize that in furmark's single-gpu mode, perhaps only the 1st video card gets stressed and not the second one. You might need to take out one of you video cards, and stress them seperately in single-gpu mode. If both cards can pass the single-mode test individually, it'd be very likely that driver is the problem for cross-fire instability.

Both gpu's are in one card.

Well I updated to the latest drivers but still get a reboot when trying to run FurMark Multi-Gpu test.

Must be a bad GPU or PSU. Btw are you using furmark v1.8?

I once had random reboot issues on a new rig....mostly during games but it could appear anywhere.  Ended up being the CPU....when hyperthreading was disabled everything worked fine.....so we replaced the CPU and no more reboots.
