Just tried overclocking to previously stable settings and after saving and exiting from the bios my system just hanged at the enter bios screen! My mobo is a p5nsli and is suppost to auto reset to default bios settings in case of overclock failure. However, all that happens now when i turn on is that it boots to enter bios screen and hangs, nothing happens when i press delete to enter the bios. Also, the hdd led stays constant! I'm worried my PC has had it, please help.
