when i first start up my computer, i can use the keyboard to choose which options i want, so i know that it works. the mouse is also lit up, but after i get past the windows welcome screen, the mouse dies and the keyboard still has the numlock light on, but none of the buttons work. i just fixed the windows/system32 error that i had for a week, and now the computer is working cept for the mouse and keyboard, so i cant really do anything. any1 know wat to do? please help!!!
