Pc Power

My PC usb ports often stop functioning. I recify this by shutting down turning off the tower on/ off button etc to ensure all power is cut off.
I reboot after a little while and all is well.
This has been going on for some time now, what exacly is going and how can I rectify this permanently.

Maybe your USB port is malfunctioning. This happens with all your USB ports?

That's a new one on me - I've never heard of that happening before!

The first thing I would do is get onto the PC manufacturer's web site and make sure you have the latest chipset drivers and any other motherboard related drivers.  Also make sure your BIOS is up to date.

In device manager, are the front and rear USB ports listed separately?  If so, do both front and rear ones both stop working at the same time?

Do you have any external USB hubs?  If so it could be that the hub isn't getting enough power from the USB port.

Hi,

What power management configuration are you using? It's possible that the USB ports are bing powered down?

Selected Power down of USB ports normally occurs on battery power but if a custom pwr mge plan is used, this could be the culprit?

If in fact the motherboard USB ports are compromised you would need to install a PCI card with USB ports on it in order to have access to working USB.

Weird. I had never heard of this problem either until recently when one of the Dell Optiplex GX280 machines in our organization had the same problem. I completely rebuilt the machine, updated everything (except the BIOS), checked that the USB take-offs for the front USB ports were firmly seated on the m.b. but still no good. The USB ports would work for a few seconds at random times, but mostly, they were off. Weird thing is, the wireless keyboard and mouse, which had a USB receiver, never stopped working. That made it hard to conclude that it was a hardware problem, like maybe something on the motherboard failing. I couldn't afford to spend any more time on it so I swapped in a different GX280 and all was fine. I still have the old machine so I'll be monitoring this question, hoping for a solution.

Sorry I couldn't be of more help, but at least you know you're not the only one.
