have a Emachines T6412 model. I recently got a web cam and installed the wecam, worked fine, loaded the disc that came w it everything... Few days later i unpluged it from usb and later plugged it back in.... I noticed the webcam didnt register on startup menu altho i tried it and it did work... Later that night while on a web page my pc shut of almost like the power plug was unpluged... Then i pushed on button wouldnt boot.. Goes to f11 menu w o me pushing f11 the menu that says --- safe mode safe mode w networking last know configuration ( that worked before) ect... All it does is try n boot and go right back to same menu...This sucks any sugggestions.... Also the safe mode wont work everytime i try and go in safe mode it goes back to the same f11 menu
