Asus P5K Startup Problem

[King Leonidas]

Hi,

I recently got a recurring problem. I really absolutely nothing changed in the bios, All that happens when I run the vga fan and the hard drives and DVD burner make "noise", then pc turn offs suddenly off. After 10 seconds rest, repeat this process again.Here is my pc configuration.

• Asus P5K
• Intel Core2Quad6600
• geforce 8800GT
• Antec Sonata III 500W
• Kingston 2 x 1 x 2 667Mhz Dual Channel 4GB
• Windows Vista 32bit

Try clearing the cmos via the jumper. Does anything appear on the screen, do you get a post beep before it reboots? I can assure you that its a bios problem, I think you must update your bios, Download latest bios update from Asus , here is the download link from where you can update bios. Asus P5K
