You can try setting up a console and have the system post there. It sometimes catches things. But until then I would do the obvious... Make sure the system is clean and not overheating from "dust bunnies" filling up the chassis. Remove and re-seat all cards and ram. Make sure all fans are working. Run memtest overnight if possible. Look back to when the reboots started and see if something was added or upgraded. -------------- next part -------------- A non-text attachment was scrubbed...
