Thanks, Nothing in event viewer that would indicate anything , I have tryed ghosting w/ windows7 and Xp both os do the same. when thru everything in Bios, turned of all sleep modes, turned off all on board componits like nic and audio and video and went w/pci cards. everything works great the pc stays on all day but every morning i have to reboot. and when i reboot it doesnt indicate it was shut down improperly. this ones got me baaaafooned?.LOL
