System won't load keyboard and mouse at start
Hello everyone,
While I was in the middle of using my system, all of a sudden the mouse and keyboard stopped working. I had no choice but to press the switch button to shut it down. I removed the battery, the power cable and all the input devices (Keyboard and mouse). After replacing them back I switched the machine ON, and I could see the flashing light on the Keybard, and the mouse light also ON (red). The memory count starts to the end, on a black screen, and then followed by the blue box at the bottom left of the screen where written "F1: Save Changes".
But I can't get rid of it this time because the Keyboard doesn't function/respond.
Machine Desktop HP 7100 CMT, Win7 ultimate 32bit, IE11, HP Keyboard PS/2, HP mouse PS/2.
I removed the HD into another machine, it works without any problem. Therefore, the problem seems NOt on the HDD side. All the keyboard and mouse work properly on other machines.
I changed the Keyboard to USB but the same result. I removed all the memory modules of 4GB in total, and replaced them with just one stick of 1GB, again no change, still can't move past the black screen to record the change, or to advance to Windows, or to access into BIOS setup.
I did this with and without HDD connected, but with the same result. I inserted the Installation disc into the DVD Drive for repair or recovery, it didn't make sense because it required the command "F1: Save Changes" must first be accomplished. But it doesn't go beyond this as the Keyboard doesn't respond. Of course, I can't get into BIOS, nor use Safe mode, because the Keyboard doesn't function. Finally, I got stuck. I really appreciate for any help, please.
Thanks
