Usb Port Stops Working, Still Has Power

My usb mouse, keyboard, microphone, etc randomly just stop working; However, It has power. the red lazer on the mouse is on, num lock is on, mic light is on, it just doesn't work.

I've tried:
re-installing mouse/usb/keyboard drivers
updating bios
unplugging and plugging it back in
plugging it in to different port (works, but stops working after about 10 minutes and then i have to restart)
uninstalled .net and reinstalled
turned off ability for usb to sleep


only temporarily fixes if I restart. Every time it happens it seems to be happening more frequently.


This started happening when i opened my computer to clean it.. IDK if the mobo is malfunctioning, can anyone please tell me if they'd had this problem and how to fix it?

Specs:
Gateway dx4860
8gigs ram
intel i7
radeon 6770
windows 7 home premium


but seriously, someone please help, is there any costless way to fix this?



I have the same problem as:

http://www.tomshardw...stop-responding
http://www.tomshardw...em-driver-issue

it could be that i short-circuited the mobo? ( i cleaned the fans with a feather duster. )


Thank you anyone that may be able to help me fix this.

Install the latest drivers, use different USB ports (Frontal ones if you have), if it doesnt work try in another computer the mouse, mic and keyboard. If they dont work... buy another mic, keyboard and mouse. If it works try to replace ONLY the mobo.

Good Luck!

Please, someone help me find a solution. it's not my mouse or keyboard or mic. the ports work fine and supply power but it stops working randomly! this is why i don't think the mobo is damaged...

¨feather dusters work by strong static charges; yes you may have damaged your motherbd. ¨

popatim is right. Your mobo is damaged.
