Boot Issues

[platypus]

I cannot get my pc to boot.

This morning I had an over volting warning, and that the bios was being reset to defaults. I've had this before, and resetting the bios then resetting the overclock has been fine in the past.

Now however, all I get is the fan on the graphics card spinning up and then down, and this repeating. No boot .

I don't (currently) have a spare gfx card to try though can bring one home from work tomorrow, anything else I can try?

Hmm ok I reseated the memory, and its booted.

With the same error message; "System has experienced boot failure as a result of overclocking" (I think). Now that I've got it booted, is there anything I can check? I've left it at default speeds for now.
