Random Reboots lately... any idea what the cause is?

I know its not CPU temp, because its pretty rock solid at 46 Degrees Celsius. I had it randomly shutdown recently and was unsure of the cause, booted back up and it worked fine. Only seems to happen when I am doing quite a bit on the PC, and I think it may be a Video Card heating issue, or something like that, but not too sure. Specs for system are in sig, and the video card is an ATI 9800 pro. I hadn't had any problems with the system until just last week and most of the crashes have happened when I am gaming or watching a movie (I run FFXI at 1600x1200, not sure if that might be higher than what the card likes)
 
Not sure what you meen with the reboot instead of bluescreen... I get I am playing a game or doing something and all of the sudden its the booting up screen. What did you mean, Sniperruff, about the BT thing?

Oh yeah, turn off the "reboot instead of bluescreen" option. I don't know how to do that, so google it. 😛

he means...<start> - contorl panel - system - advanced - startup and recovery - uncheck "automatic restart"....

Any error that would usually give a BSOD or dump will now just reboot and then should give some kind of windows error message...deciphering can copme from understanding that thing as well....

Avoid some firewall and AV software running in background with SP2 installed with games....I had to switch away from zone alarm for that reason (awhile back)...installed SP2 and then when and if zone alarm was on during NFSU 2 it would BSOD....I turned off AV (built into the suite model) and it ran fine but then would eventually BSOD...removed them both and used windows firewall and the issue never occurred again...on my sons PC...With the AV the BSOD were random but seemed to happen enough since he played it a bit...
 
Interesting about Zone Alarm. Guy at work had the same problem when he upgraded from one version of zone alarm to another not sure what the versions were though.
 
From your sig it looks like you're overclocked. I got random reboots from my seemingly solid 1.8@2.2ghz Barton, I think certain programs just tax your system more. Of course, mine could be heat related cause my HSF is a POS. So even if your tests showed your CPU to be rock-solid @ 2.2ghz, try lowering to stock speed just to see if the problem goes away.
 
Can you get into safe mode without it rebooting when your in there? If so then try uninstalling your video card driver from device manager and then reboot and reinstall your Video drivers after that from normal mode (regular Boot).
 
'Runs for a while, then reboots' is usually a sign of either:
- Memory instability, or;
- Heat build-up.

10 successful scans of Memtest85 Test#5 should resolve whether or not your memory settings are OK.

Heat-buildup could be caused by:
- CPU cooling insufficient/marginal.
- Video card (if overclocked - unclock and try it for a while),
- Chipset cooler interface (check thermal compound, possibly lap the chipset contact area).

Those are the items I'd check.

Hope this helps!
 
Word ^^

I had instabilities just like you describe, and I'm fairly sure it was a RAM issue.
Lowering the RAM speed helped and now I don't have the issues.
