I am having troubles with a Compaq Presario 5460. I turn it on, it loads Windows 98 SE, but when I get to the part where I am supposed to enter my password, the keyboard nor the mouse work. I have hooked up the same mouse & keyboard to another computer, so I know it is not there. The lights on the keyboard flash when the computer 1st turns on, but nothing after that. What could be the problem & how do I correct it? TIA!
