USB Keyboard problem, General USB port Problem

Hi There,

I have this weird problem with my USB keyboard.  My keyboard is not functional in the DOS; however, when the Windows loads it is fully functional.  I am trying to get to the BIOS but I am not able to.  Keyboard won’t work.  I tried using other PS2 keyboards as well and they seem to be having same problems.  This started to happen after my Thumb Drive crashed and Blue Screen came on while on Windows.  Since then I had problems accessing some of the USB ports that are attached to my Motherboard.  My Pocket Pc Won’t work and My Web Camera Won’t work.  Also, I tried buying Belkin USB hub but still none of the device seem to work on that either.  Any ideas how to recover from this major problem would be greatly appreciated.    Thanks in advance.

but the problem is that i cannot get to the BIOS.  when i restart my machine and black screen comes on keyboard is not functional.  sounds weird.  i know.  however, when it boots to the windows and login prompt comes up it becomes operational and i can go head and login to windows.

any further suggestions as to what might be causing keyboard not to be functional only in DOS.  ???   any alternative solutions how to get to the BIOS without keyboard support??
Depending on your operating system if its XP you can try to restore it back before the crash happened if its not then you can save a lot of time and headach. back up your data and reinstall your OS.

It is an XP pro.  I'll try restoring the OS but i doubt that's going to work.


Try a PS/2 keyboard. Do not have any USB components connected. If a PS/2 KB doesn't function during POST/startup (you cannot enter BIOS setup etc), you're in trouble.

The thumb drive may have damaged something when it broke down.

try locating  a same motherboard, as in your system and replace the bios chip, or you can have one here :

or simply try flashing your bios :

Just a thought:

You said  you tried other ps2 keyboards... did you do that with computer on all the time? You have to completely turn off your machine in order to try ps2 devices.

Strange, i thought he could not get into the bios ??
Unless he uninstalled the USB controller drivers and then it worked?
