Aww, crap. I thought it might be something nasty.
The power button does nowt. The restart button resets it, but then it goes back to the beeping again.
It's unlikely to be a virus - my comp isn't physically connected to the internet. The only link is a large pile of CDRWs and floppy disks that get formatted and virus-scanned on a regular basis, and two flights of stairs.
Oh....****. Another thing I just noticed. My mobo has a fan on the Northbridge, and it ain't spinning. Could that have cooked it? It looks like a pretty crappy fan anyway, just clipped on loosely, but the chip itself barely has a heatsink - just a metal plate with some little bumps on it.
Another possibility - my PSU was fairly cheap - could it have surged and fried something? I dunno, the keyboard LEDs flash when I switch on, the CPU fan, HDD and DVD drive still work (at least, the HDD hums, and the drive oopens and closes), and the GPU fan still goes as well.
I'm gonna leave it till Wednesday, and then switch it on again, and see if it works. Anyhow, any more help or ideas would be great, and I'll try anything - I can't afford a full new system at the moment, and I need the stuff on my HD!
However, at the moment I'm going to bed. I've got school in six hours, and I'm going to a gig in the evening (Darling, Amen and The Wildhearts!!!!) , so I've got to go or I'll be knackered. I just hope things look better in the morning...
