I had this same issue in two cases.
1. The keyboard failed. It didn't work on other machines either.
2. The motherboard had failed. I couldn't run Linux on it so that was my second clue after XP would not work proper.
There is a clue this machine may need repair. Here's the clue -> "hercules". That maker has not been seen for over a decade.
I have problem during installation of windows xp pro, it began a beeping sound every time i hit the keypad while entering the serial # & wrong character appeared then the computer freezes. What is the problem? can anybody help with my problem.
my comp spec.
Pentium 4 2.8 ghz
128 mb video card geforce
maxtorr 40 gb
sound blaster sound card
video action (hercules)
Thanks in advance...
