Yeah I got this weird problem about a month ago. Any mouse I try on my comp is not working and same with usb devices. They work perfectly on other computers.
I've tried to format my computer. It didn't work.
Nvidia geforce 8800 GTS 320MB
Intel dual core *insert numbers here* 2,6ghz
nForce 650i ultra motherboard
I'm thinking of buying a new computer, but I got an idea to ask here first.
