keyboard and mouse frozen at installation

[trandal]

hi there

i have a compaq presario laptop and ive been able to get to the install screen where you choose your language. however, the mouse and keyboard are frozen. even if i plug a usb mouse in, it doesnt do anything and just sits there. ive searched the forums and stuff, but i couldnt find an answer.

what can i do? if there is an answer, just give me the link. thanks in advance
