I recently had to wipe my wife's hard drive after she had loaded some "windows" programs (they were NOT windows programs, and jacked her computer). I took the hard drive out of the case, formatted it on my computer, then stuck it back in her case. Unfortunately, I forgot to set it to boot from CD and when I powered it up I got nothing, no bios at all, and it would not boot from the Windows disc. Seeing that I am not getting any BIOS at start up, is there something wrong with the motherboard itself? I may be showing my ignorance but this is how we all learn...any ideas would be GREATLY appreciated.
Power off the monitor and then on again, it looks like the PC is running but you have no video. Do you have a dedicated video card or you're running an onboard one? Try some other video port for the monitor. Do you have some other monitor to test the PC with?
