problem help...Bio`s (hardware ?)

If clearing the CMOS didn't do it, I'd try a BIOS update using the Floppy. The alternative would be to disconnect everything and see if you can get into the BIOS. If you have to sticks of RAM, try each one at a time. If you have more than one hard drive, try one at a time.

Really sounds like a BIOS problem given you keyboard is recognized if when you hit delete you get the message it's entering the BIOS. I don't know if you can do a BIOS update off a USB Flash Drive, you'd have to check the motherboard support site to find out. Floppy drives are about $7 or $8 at newegg, probably more at a local brick and mortar. If you can't do a BIOS update or it doesn't work, I'd RMA the board if it's still under warranty. As for the number lock on the keyboard, not sure how that is affected by the numlock settings in the BIOS. I know the consensus seems to be that Floppy drives are old tech and unneeded but when you run into problems like this, they seem to be the only answer, which is why I also install a Floppy drive.
