Usb Port Stops Working, Could the motherboard be broken?

[maklapro]

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?


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

sorry no answer, but I have very similar issue. My usb mouse would briefly stop working every ~20 seconds (like a lag spike). Occasionally, both the keyboard and mouse would just completely stop responding. Even after re-plugging the usb devices, I'd get no responce and I'd have to reboot.

This happens for both front panel usb ports and back; I've updated my mobo BIOS and reinstalled the drivers.

OS:Win 7 64-bit
Mobo: MSI Mpower Z77 (Big Bang)
