Aspire 3100 touchpad and mouse not working

I have an Ace Aspire 311-1566 and I was on internet getting ready to type an address in address bar when the mouse froze. I rebooted and windows started OK and got to log in screen and still no mouse or keyboard. I thought is was maybe a bios issue and still no sure but I unsoldered the CMOS battery and resoldered to try and reset and they still don't function. I myself have worked on a lot of computers and never ran into this problem. I have also always used a usb chill pad to keep it cool. I also reformatted hard drive by using an external usb drive case and reinstalled harddrive to do a recovery because I did create 7 recovery disk when I purchased it in Nov 06. I also went to a computer store to purchase a usb keyboard and before I buy I connected it to see if it worked and it did not function, also usb mouse did not function. Everthing else works fine except touchpad and keyboard. Any ideas are appreciated. Like I said usb works because my chill pad and usb mouse lights up. My mouse is stuck in middle of screen.
