I have a Gateway Astro...just the other day the keyboard and mouse stopped functioning...this Astro has only USB ports...no serial and no ps/2 ports and furthermore, no room for them...it has four usb ports...two on the back...two on the side (its an all-in-one style puter)...the usb ports have -5vdac coming through them and when I brought the keyboard and mouse to college...they both are functioning properly...my computer teacher said that it could be a fuse blown...where the hell that would be...I have no clue...people have been telling me that the problem could lie in bad device drivers or whatever and there is no way that I can get into it to check...anyone have any clue??? thanks for your help in advance...
