USB ports suddenly stop

[ziadramman]

Hello,
Hey guys, been facing a problem in the recent month, every 5-10 hours one (or all) USB port(s) just stop working, they drop out, and im forced to restart the pc (unsuccesfully), i have to hard reboot.

I dont know what could be causing this, no virus's etc. Any thoughts would be appreciated.

Have the ports been setting idle for a while when it does this? If so check the settings and see if the USB ports are set to sleep or hibernate after so long.

Hello,

Another thing to help pin down the problem when that happens, is go to the 'Devices and Printer' page, and see if the USB device is listed in the lower area as a problem, unknown, or gives you an hardware error code. May help point you in the right direction.

As Al noted, it may not be a hardware problem since sometimes 'all' the USB ports act up.

Hey guys, thanks for the replys.

The USB ports are NOT idle since im using them at the time of freezing. I went as you suggested to the Devices and Printers are, and there are no problems listed.

I think this might be a power issue. Does instability of power cause such things to happen? Or could be IRQ problem?

Thanks again.

Power (voltage or current) issues are like 'a silent killer' since they are transient and really hard to track down.

When you note a single USB not working, check in the Devices and Printers section to see if the OS flagged it as defective.
When you mention all USB ports quit functioning and you have to reboot, that speaks more to a system freeze rather than just the USB's There at next boot up, check the Event Viewer, Custom Views \ Administrative Events, to see if it logs a specific critical error.
