OT: Massive computer problem, help appreciated

[Fyron]

I wouldn't suspect a virus; boot sector viruses are extremely rare, and any virus in windows would not prevent the BIOS from outputting to the video frame buffer in the bootup process.

Hmm... the beep codes for AWARD motherboards (which a biostar is) are quite varied, so I can't find what that exact code might mean, but it should be happening every time.

You should taking your RAM out, then putting it back in. Sometimes major errors like this occur just because the RAM is slightly out of place.

It's memory I betcha.

I had the same problem with my dads computer. It turns out that the long beep sound was in fact the memory having gone bad. Either reseat the memory like it was suggested, or if that doesn't work, see if the RAM works in another computer. If it doesn't... yup, memory is bad.
