Hello everyone.. I have a bit of a problem with a PC I just built. Ok. Everything seemed fine and everything appears to be in working order. Now sometimes when I flip on the power supply the computer turns on by itself, all of the fans are running etc.. and then about 5-10 seconds later it shuts off.. From there you can trun it on via the power button as usual. Why is this happening? I have read some other fourms/posts and someone had said to check the wake on LAN, boot from USB etc.. in the BIOS to see if it was enabled, but it is NOT. Let me know if anyone has any ideas. Thanks in advance..... System Specs: Asus P5W-DH Deluxe Intel C2D e6400 2.13 GHz ATI Radeon X 1950 GT 2 250 Gb WD cavier Hdds Corsair 2 GB DDR2 XMS memory Card reader, DVD-RW, etc.. Dual boot with Windows XP Pro and Windows Vista Business.
