Computer wont start normal or safe mode! HELP PLEASE URGENT!?

I knocked the power plug on my computer about 1 hour ago and it hasnt been working since. I really need it now.
It gets to the loading screen of windows Vista Home Premium where there is a loading bar and Microsoft Company written. But then the monitor loses signal and the computer starts over again.
God this is so annoying because Im screwed for tommorow.
I think Ive fried something and Im about to cry D:

Is there a solution to this? I cannot start in safe mode, it loads a bunch of windows files and stops after loading \Windows\system32\drivers\crcdisk.sys
Am I screwed? Please tell me Im not.

If you have your operating system disk then, get into BIOS, change the primary boot device to ROM drive, save the change, reboot and boot into the operating system disk and choose REPAIR. Attempt a repair. You may need to Fix the MBR (Master Boot Record) using the FIXMBR command.
