ok a few weeks ago there was a storm and a blackout in my area, a few hours later when i turned on my computer non of my usb ports work (mouse, keyboard, cam)they were all out!. now windows tells me that everything is fine with the usb ports it just won't detect anything. i reinstall all drivers did every troubleshooter i could find, i've pluged my cam in another computer and is fine. so i connected an extra set of usb on my motherboard but they don't seem to work neither. now i think is the power supply which got fried and not my motherboard
(at least i like to think that)so tomorrow i'll buy a power suplly to try and solve the problem, if not then i'll have to buy a new motherboard

Hi zeusxp, welcome to BC.
Those are two definete possibilities, though given a choice between the two, I'm leaning towards the motherboard myself. :thumbsup:
Asus in particular had a real problem with the southbridge getting fried on some of it mainboards resulting in dead usb ports. I wouldn't start right off with any HW though if everything else powers up.
A missing or damaged .dll file, among others, will also cause the same issue.
Since you really should reformat after a new motherboard installation, I'd do that first just to rule out OS corruption. For me it's simple as I keep complete system backups on individual drives. I don't know what your backup situation is though. Using the Windows system restore function in this case wouldn't be a reliable indicator. You might also consider a seperate usb card installation though if it's the motherboard, I'd be wondering what else is going to happen.

Try reinstalling the hubs as well as the ports.

Open your device mamager and delete everything in the USB section, reboot and let Windows find and reinstall them.
