USB Crash Issue?

So for awhile now, longer than I care to admit, my USB devices all crash at the same time, and come back up after roughly a minute. At first, this started happening mainly while playing games, and of late it can happen while I'm just browsing the internet or when I'm not even on the computer.

This is my first self-built setup, which I'm hoping is not the issue since it has worked fine for awhile after being put together. Processor is Intel(R) Core(TM) i7-4770K CPU @ 3.5GHz. Installed RAM is 8.00 GB. The OS is 64-bit Windows 7 SP1.

I have seen threads here/elsewhere related to this, and have tried the various fixes/suggestions mentioned, to include the following:

  • ■ Making sure the Power Management settings are not set so USB devices/Root-Hubs can be turned off to conserve power
    ■ Deleting Mouse/Keyboard devices under Device Manager until the device is no longer responsive and rebooting the computer
    ■ Deleting USB Root Hubs under Device Manager and rebooting the computer
    ■ Updating USB device drivers
    ■ Making sure all Windows updates for my system are installed

Needless to say this is getting rather frustrating, especially since the instances seem to be growing more frequent. Any help is greatly appreciated.

Ok those temps are fine.

Have you tried eliminating USB devices to see if it's one of them that's causing a problem?

It maybe easiest to just have your mouse and keyboard to start with. If the problem goes away, then it's one of the devices you have unplugged. If not, then it could be either the keyboard or mouse, try using a substitute for either one at a time (hopefully you have one or can borrow one), and if this doesn't fix it, then it's most likely a malfunctioning motherboard.

One other thing, and I thought I mentioned it already, but I guess not. Go into the BIOS and look under your USB settings and see if everything is set up correctly (default), you could even try making some small changes to some of the settings to see...

It could be that you have a malfunctioning / shorting USB device. If the USB device draws too much current, the motherboard may shut power off to it and any other devices off of the same Root Hub.

Try to disconnect one at a time and test to see if the behavior goes away. Of course you'll want to leave the mouse to last, or if you have a back up try it.

The USB ports on the front of the computer should be a different hub from the back, right? I had thought it might be a power thing, but both the device plugged in the front and the devices plugged in the back die when this happens.

Never thought to try that. I'll give it a go this evening and find out.

[UPDATE]: Tried it out, still crashes in Safe Mode. However, on a whim I checked the temp of my computer. CPU cores were 35-42 C, and the GPU/Hard-drive temps were reading max. I obviously need to find a way to fix this, but is there a decent chance that this is the cause of the problem? It'd make sense if the frequency of the USB crashing went up with the temperature approaching summer.

That's an odd combination to have with high temperatures? The HDD and GPU are reading max? What is max? And what are you using to check temperatures with? There is a chance the program isn't showing the correct values. However if they are correct, either could be causing your system to hitch. You would think that your mouse had stopped working so you may interpret this to be the USB failing.

It's certainly worth looking into, if for no other reason than the longevity of your HDD and GPU. In fact I'd be more worried about that for the moment. How is the airflow in your case? Also what is your chipset temperature?

I'm using Open Hardware Monitor 0.6.0 Beta. Temps are:
CPU Core 1 - 35C of max 48C
CPU Core 2 - 34C of max 47C
CPU Core 3 - 35C of max 41C
CPU Core 4 - 33C of max 39C
CPU Package - 40C of max 48C
GPU Core - 38C of max 38C
HDD - 32C of max 32C

Air flow wise, just the fans that came with the case and the chip fan that came with it.

You haven't mentioned what motherboard you have, but I assume it's has a UEFI BIOS. Therefore the mouse and keyboard work in there, when you are in your BIOS do you have trouble with your mouse?

So I switched out keyboards first, and I noticed the mouse stopped like normal, but the keyboard didn't. I had the keyboard plugged in a different port, so I swapped the mouse out in the same port, and it has yet to 'crash.' I'm still not sure if it is something where those devices where 'registered' somewhere and they got toggled, or if it was the fact they were slightly fancy-smancy gaming devices, and I have ordinary ones currently plugged in. Kinda lame if it is the latter.

Anywho, marked your last post as Solution, and did +1 score to all your posts here. Thanks much for your help!
