hey guys was just wondering if anyone has the issue of, if i leave my computer for about an hour unattended when i come back if in endlessly powering on and off. but i can use the computer no problems if i don't let if become idle, used it got about 12 hours straight no issues at all yesterday. if any one has any ideas that would help alot. i already checked and changed the video card, hdd. don't see how it would be the power supply and i don't have a spare atm .

Prob in BIOS. I would suggest that you look in Control Panel / System / Advanced System Settings / (which will give you System Properties) - Advanced tab - look at Startup and Recovery - click the Settings button : uncheck box "Automaticaly restart" Then, if you get a BSOD, it will not auto restart. I suspect you're getting something like a BSOD from a memory error and when it automatically reboots, your BIOS is unable to POST your system because of a memory problem (timing, voltage, defective memory, etc) so it auto re-boots to try again. This can of course be cleared by shutting off the PSU switch in the back, waiting for 15 seconds, and turning it back on. But if your memory or settings are borderline, it will simply happen again. This is an unfortunate occasional artifact of BIOS auto recovery, where it tries to lower the settings to a point which will enable the system to POST, and other conditions on the mobo won't allow it to succeed. Hope that helps. Kris

hmm i guess i'll just change stuff until it stops, thanks for the tips.

shadowsabre - If you can get it booting properly anduse it for 12 hours straight - but if you walk away from it, then something causes it to go into this infinite booting loop- you may have an issue with sleep as well. Sleep/standby and hibernation have been known to cause problems for some users and if that's the case, it's recommended that you disable sleep/standby/hibernation entirely until a fix is either made available or the final version ships - which should have these issues fixed.
