My computer set-up:


CPU : i5-4670K
Motherboard: Gigabyte GA-z87-d3HP
GPU : Radeon R9 280x 3GB
PSU : XFX 850 (Recently changed to check if it wasn't a PSU problem)
OS : WIndows 8

This is an ongoing problem, recently my computer had problems. It would randomly freeze needing a hard reset, and the USB ports would randomly shut down and restart.

I've gone through a thread, updated my USB drivers, and changed my PSU. However, there is still the USB shutdown problem. No hard reset anymore.

When playing games or doing moderate load operations on my computers, my USB ports will lag (basically my mouse will stop moving, or my keys input will input the same key for a few seconds), and sometimes even shutdown, disabling my headphones, my keyboard and mouse for 3-10 seconds before coming back on.

There's no alert marks in Device manager, and all of my USB ports are set to not turn off when the computer needs power elsewhere. I downloaded both drivers for intel chipsets to no avail.

NOTE: Just tested something: This happened when I had 3 USB (Headset + Mouse + Keyboard) Connected in USB 3.0 ports. I've now put my mouse and Keyboard on USB 2.0 ports, and the lag seemingly stopped, However there are still shutdowns.

2ND NOTE: Other Test: I've put a USB hub (Basically 4 2.0 port) on my USB 2.0 port on my computer. I've connected my headphones, keyboard and mouse on it, and the lag was horrendous, with numerous USB shutdown. I've then decide to remove my mouse from the connected port from my keyboard (I have a Razer blackwidow with the USB port on the side, that's where I was connecting my mouse).

Now my mouse, Keyboard and Headset all have their own USB port. The lag seems much less noticeable, but there are still shutdown while I download games.

Any Help on the matter? I'm starting to feel it's definitively a motherboard problem.

I found the problem : I had set my BIOS to run my CPU at 120% (Basically overclock) and it was causing my system to shut down my USB ports because of the power draw. Since I can't select my answer has best answer, I'd ask to lock the thread.

IS the hub powered? Usually this kind of shutdown happens when the USB controller on the mainboard detects that too much power is being drawn from the USB ports. Might be an issue with the mainboard - maybe the 5v regulator? Using a powered hub should at least eliminate this as a cause

a powered hub is one that has its own 5v power supply from a wall socket
