I am having a problem with my system, and I was wondering if anybody can help me out with this. Everything was working fine till last night. Right after connecting my phone into the USB, my desktop's screen went black and the mouse, keyboard, and even the DVD player stopped working.
The fans and the light are on and running fine, but nothing else is working. I've tried cleaning the memory and video card, also bought a new power supply but nothing is not solving this issue.
Absolutely ingenious. I unplugged my laptop and plugged it back in. And now it's working again. The keyboard and mouse work. Even the shortcuts which I lost temporarily are working again. THANK YOU SO MUCH! I can't begin to imagine what caused the problem and why unplugging the laptop solved the problem. But my computer is working again.
I had the same exact problem on my computer. Unplugging the power supply from the computer and from the wall and then plugging them back in did the trick!! I don't know how you figured that one out but it definately works!! Thanks for the help!!
mine's still not working I don't know what happened but my monitor still says it's going to sleep and the mouse and keyboard dont work what would it be???????????
I had the same problem and the following fixed the problem:
Since your USB keyboard & mouse doesn't work, you'll have to use one of the following to access the computer:
1. Use a PS/2 kbd & mouse.
2. Use a remote login session (assuming that you've enabled Remote Desktop previously).
Now remove & reinstall USB devices as follows:
1. Click Start, click Run, type sysdm.cpl in the Open box, and then click OK.
2. Click the Hardware tab.
3. Click the Device Manager button.
4. Expand Universal Serial Bus controllers.
5. Right-click every device under the Universal Serial Bus controllers node, and then click Uninstall to remove them one at a time.
6. Restart the computer, and then reinstall the USB controllers.
7. Plug in the removable USB storage device, and then test to make sure that the issue is resolved.
There's a problem with your fix here Wuu. If your screen is blank there is no way to access anythign helpful to reinstall. I have the exact same problem right now, the power button on the main HDD turns and so does the card reader near the bottom of the tower. The problem though is that the DVD Drive, the Monitor, and anything supported by USM doesn't turn on. I myself am not a computer hard ware type but it seems that I will start to learn as I slowly fix this computer.
