ok, thanks ppl. I cant get to the BIOS cuz when I turn the computer on the screen is black and it BEEPS at me. Ill try no jumpers. The old hard drive is no good cuz it crashed. I made sure the new hard drive is ATA-100 cuz thats wut the old hard drive was.
You should be able to get to bios even if theres no harddrive, if you're getting nothing but a blank screen then your motherboard might be fried.
