if this happen only in front USB you can open the case, unplug the dameged USB connector
and replace it.
if this happen on all USB plug it could be bad driver.

another way to make sure it's electric problem is to check if the computer
suddenly  shut down and turn off (or reboot) or do you see flash off blue screen (with error)
blue screen means that you mey have driver issue.
sudden death - electricty problem.

that's it... i'm done!

So there are no ways to fix the electric problem besides replacing the USB ports up front?

Yup, don't actually plug it in or insert it in the slot just run the metallic part along the metallic part of the interface or use a key or some other metallish device to touch the OUTSIDE surface edge of the usb interfaces (don't need to insert anything).  I found this prevalent with a particular motherboard... Intel D865GBF? when used with a particular Antec case...  It only happened on either of the two front USB connectors.

I think your best bet I think maybe to go in if you and unplug the reset switch, a two wire connection running from the motherboard to the front of the computer.  Refer to your motherboard manual or perhaps there is a large white motherboard diagram on the inside wall of your case.  Certainly easier than reseating the entire motherboard and the only thing that worked when I tackled a machine I found doing this...

the front USB plug should cost you almost nothing in any computer shop.
so if sure it's the problem i wouldn't mess with them!
you can do more damage to the mobo...

Hi deadwalleye,

Thanks for answering my questions, this makes troubleshooting a little easier.
As all answers where "yes" I advise you to look into short circuits as pointed out by haim96, it could be an electronic problem.
As you mention it only happens with these ports it could be that something has moved a little and is shorting the case.

Regards,

LucF
