Hi, I have a problem where my pc is stuck at start up on the first screen where there is options to hit Tab to go to POST setting or DEL to go to BIOS. however, nothing works, and the screen remains stuck there. I have tried to clear CMOS jumper setting, and also tried removing the CMOS battery. All this to no avail. Can someone help? What else can I try? My pc running on Windows XP.

Are u sure the keyboard is working?Have u try to test your memory(using memtest)or if u have another stick of ram try it.

If it's not a keyboard problem: Try disconnecting devices from the motherboard, one at a time. Hopefully you will discover that one of them is causing the problem.

it is possible that the bios is corrupt u can try downloading a bios flash from the manufacturer from another pc put it on floppy and try to flash it the manuf usualy has instructions on how to flash the bios
