USB crashes computer - turns to black screen.

Specs: Windows 7

When I plug in a USB, my computer goes to a black screen. Could it be static electricity from the carpet? What to do? How do I get it back up?

You go to Windows safe mode from the start up screens. Tap F8 repeatedly when the computer first starts. If you don't have video when the computer first starts you have a hardware problem.

To add to the above reply, does this happen when using front USB or back USB ports that are on a bracket and NOT connected directly to the motherboard?

Also: Is the power light still on when the screen went black? If it is, try holding down the power button until it completely shuts off, the then press again to restart it.

You have to be a little bit crazy to keep you from going insane.

Last night I unplugged the computer and then plugged it back in and now it has come back. But I'm afraid to use the front USB ports again. I wonder if it does have to do with static electricity. Anyone heard of that causing such a problem?

Is this a new build? The front ports may be connected to the motherboard wrong. The wiring can be confusing and you may even have them connected to a fire wire header.

Did the front ports ever work correctly?

This was built in September. It has worked correctly in the past. It just happens sometimes, more recently.

Could be overloading the USB Controller. USB controllers usually serve TWO USB ports. In your case those would be the TWO front ports. It is also possible if you have a built-in card reader that it is also running off that same controller. If you have a high current device connected to both ports it can overload the controller.

If you are connecting an external USB powered portable hard drive they usually require TWO USB connections to operate correctly. If a USB external drive is failing it can place a bigger load on the port. You can test an external by downloading software from the manufacturer's site.

In your original post you ask about static discharge. That may be possible. To avoid that touch a metal part of your tower to discharge yourself before touching the USB cable/ drive.

I am having a similar issue, except both the front and the back (MOBO) USB ports are effected, as well as the headphone/mic jacks. The monitor goes black, Fans, and LEDs are still on. Ive checked my graphics card about 3 times to see if it is seated correctly. It is. Should I pull it out and dust it?
This issue also happens when I shock my light switch, or I turn my other computer off in the other room (Same circuit).
I also have the computer resting on an anti-static mat, but that doesn't seem to help. Windows tells me my graphics card driver has failed a ton of times, but everything is up to date. It asks me to give more information about the problem and I get sent to an HP laptop site asking me if my laptop was plugged in at the time of the occurrences.
All of my electronics are plugged into a high end surge protector.
I am confused, please help me, I have been dealing with this for 8 months
