USB ports intermittently not working

Not sure if this the right forum but I hope so.  My son is running Windows 7 on his desktop gaming computer (custom build).  He uses multiple usb connections, including headphones, mouse, and keyboard.  Over the last few months he has had increasing problems with his usb connections.  It started with his mouse freezing for short periods of time; then it moved to where his headset will stop working entirely.  Switching to different usb ports helped at first, but does not seem to make much difference anymore.  It has gotten to the point where he has to shut down the entire system and reboot.  Sometimes this temporarily resolves the problem, and sometimes it doesn't and it will start freezing up all over again.

 

Several months ago he installed a powerful new graphics card (r9 290 tri-x).  I have read on some sites that usb issues could be caused by the power supply not providing enough "juice"; however, he is running a 650 watt power supply (corsair tx 650) which most sites say should technically run his graphics card.  I have also read some things about possible motherboard problems.  We tweaked some usb settings so that the usb ports are not allowed to be "put to sleep" by the computer - it worked for one day before freezing again.  We are not sure where to go next with this.  Hate the thought of hauling it somewhere to pay to have a "specialist" look at it, we would rather try to fix it ourselves if possible.  Can anyone offer any insight/suggestions?  Thanks.

 The contacts in USB ports can wear lose after a lot of use.  However, since this is a desktop, he can buy an inexpensive PCI or PCIe card with more USB ports.  The PCIe ones start at around $15.

 

Good luck.


Everyone with a computer should back his system up to an external hard drive regularly.  :thumbsup:

Thanks. The PC is only a year old but does get heavy use. He has an external USB hub but that's been cutting out as well. Is a PCI card something external or something internal that would need to open case to install?
