Black screen

[Hyper-Threaded]

Ok the specs of the computer are below, I went in the BIOs and changed the clock multiplier for the CPU from 250 to 300mhz, and it said the max was 450mhz, so its reasonable. I saved it, it restarted and went to a blank black screen. The moniter is on, just displaying black, I have tried 3 graphics cards, re-seting CMOs jumper and removing the battery. Still black screen. Can anyone help?

Remove the battery and set the cmos jumper to reset and leave it for about 15 minutes then retry again.

Yeah, the BIOS has saved your settings and needs to be reset. The black screen means that it cant boot with the OC you did, either lower the base clock, and up the multiple instead, or increase the vcore voltage.
