I flashed my bios....

[VaZarD]

and now i cant do anything

Computer turns on, does memory check and then freezes
i cant press del, alt-f2 nothing cannot get into anything or do anything.

I got the latest bios flash from the website for the right mobo and the flash said it went fine. then i restarted and it just stopped at end of mem test, ive skipped etc etc.

Any ideas at all?
