Windows 7: USB device not recognized in Windows 7?

USB device not recognized in Windows 7?

I have the strangest problem I've yet to encounter with my computer.
As you may have guessed from the title, I am constantly getting the message displayed. Any fix that has been suggested has been unhelpful or worked for a bit until my computer restarted again (I'll get to that)
First off it started when I noticed my mouse pointer was acting very weird, it was just a vertical line of dots. A forum said an easy fix to the problem was to update my GPU drivers, which I needed to do anyway. So after an update to the GPU drivers I log into my computer (which is password protected, this is slightly important to remember) and I try to go to youtube. I click down at the start menu to type in chrome and nothing appeared. I was able to move the mouse around and click on things but I was unable to type anything.

Luckily for me I have a laptop as well so I checked for any solutions on my laptop and they said that it was a problem with the model of my keyboard specifically This was odd to me considering most of the problems happened OTB for the keyboard and not a month after use, plus I was able to plug it into my laptop and it worked just fine. When I plugged it back into my desktop it gave me the same problem: I couldn't type anything, I also noticed the little pop-up informing me that the USB device was not recognized. "Well, great, time to get my backup keyboard," I thought to myself. Except, that was not the case either. I plugged my backup keyboard into every single USB port on my Computer Tower, even going so far as to unplug the mouse. Absolutely nothing was working. I constantly restarted my computer and each time got the same problem; I'm able to type in my password to log in and then a few minutes after that the USB device stops working. Sometimes after plugging one of the keyboards back into a USB port I would get a message saying it was installing drivers; and then would fail in installing any.

After a bit I navigate through the menus with just my mouse and do a system restore to before the GPU drivers were installed. After that, I started windows in SafeMode and then turned my computer off. Finally, I unplugged my computer completely of all plugs (including my power plug), waited a few minutes, then plugged everything back in again. Amazingly, this fixed the problem, but then it got worse.

After about an hour of gaming, my computer BSOD's, most likely because I decided to alt+tab out of Tomb Raider during a loading screen to stop a video I had on. I restart my computer again, and then the problem returns, only this time absolutely no USB devices work except my one keyboard. The backup keyboard, and both my regular mouse and backup mouse stop working a few minutes after logging in. I try to fix the problem like before, but to no avail. Any USB device I plug in either gives me the "USB device not recognized" or attempts to install the drivers and then fails.

If there is ANY way to fix this problem, it would be greatly appreciated.

Hello FrankieAce and welcome to Seven Forums.

Your comment that, "Any fix that has been suggested has been unhelpful or worked for a bit until my computer restarted again" doesn't say what fixes you've already tried. I apologize if you've already these:

Try going through the troubleshooting steps prepared by one of the Forum experts. It will take several hours (or overnight when running Memtest86+) to go through all the steps and it's recommended that all steps be followed in the order listed.
