I was wondering if someone could help me? The other night my computer crashed. A virus block window came up and prompted me to delete the viruse and i did so. As soon as i clicked delete the computer completely crashed. Now when i turn it on windows wont boot up, i cant get into bio settings, and it wont boot from disk. If anyone can help out i would really appriciate it.

Can you boot into safemode? How far does it boot up, before it turns off/restarts again?

You should be able to get into BIOS settings. It can be tricky to send the command to your computer fast enough as the computer starts up, but it should always remain possible (unless you did an incomplete BIOS flash). I would like more information into how it won't start though.
It looks like the time has come to recover your computer using the Vista disk that came with your computer. Your anti-virus program might have deleted or quarenteened a file that was important to the OS, so using the disk to attempt a repair on the computer might do it for you. Make sure you boot from the optical drive before hard drives first though. Hopefully you also made a reasonable backup of your files, which you should be doing often. A complete PC backup has saved me a couple of times since back when I didn't backup my computer.
