Why does screen go black and keyboard and mouse no longer work?


Hello,

I'm not sure what Operating System you are using on your PC. But from what I can see, you might be using Windows XP, Vista and/ or 7. This kind of abnormality usually happens when the computer is infected with a Trojan or Malware. Is your antivirus software upto date and functioning well? Scan your PC and clean it fine.

If this still happens, you might be having some malfunctioned hardware; Motherboard, Ram, Keyboard or Mouse. Check these carelefully to ensure that they are working great.

Lastly, if this still happens, your Operating system might be having way too many errors that it might call for a re-installation. Backing up data and doing a clean re-installation might be something to look at.

Please let me know on how it all goes.

On start up fan runs, no beeps, black screen, no response from keyboard & mouse. Unplugged everything for 30 minutes, then tried again, start up began then went to black screen, no keyboard, no m


in your case, there might be some problem with the main board.
usually no beeps will related to the processor error / mainboard error / ram error / PSU error

to check the processor : try to exchange the processor with the same type.

to check the Memory: try use rubber eraser to clean the cooper plate of the memory. then plugged it again.

in case if there is a power supply error, then try to exchange the power supply using other PC PSU.

if all steps above are checked, the problem might be at the mainboard. in that case, replacement will be the best option.

My Imac crashes. 10.6.4, 2 GB ram, 2 GHz core duo. I've started with a clean install and disabled (one by one) all start up apps. Out of the clear blue, the screen will go black & I have to turn it...


When you say "screen goes black," does the computer power down, or is it still operating? Does the sleep light come on? Does it respond to the keyboard and mouse? (Example: press the power button momentarily, wait a few seconds for the "Do you really want to shut down" message to appear, even though you can't see it, then hit the return key to answer "OK," and see if it shuts down.) Does the screen go black or come out of black if you tap the computer?
While your computer is working, go to System Preferences / Desktop & Screen Saver, the Screen Saver tab, click Hot Corners, and set a corner of your screen to Put Display to Sleep. Then next time your screen goes black, mouse your way into that corner, pause a few seconds, then mouse back out and see if your screen returns.

LX 300 Keyboard and Mouse: mouse works but keyboard doesn't...


Hi,

You can hit Window+U at the Welcome Screen, this will turn on the on-screen keyboard. Reinstalling the drivers should fix the problem

............................................................
Also to enter save mode, when the system powers up hold down F8 Key. Use your arrow keys to move to "Safe Mode" and press Enter key.

Please post your feedback.

My screen is black. I think I may have put it in


depending on how the system is set up simply pressing the power button on keyboard or the PC
If you get no response no matter what you try then unplug the PC from the mains for 10 seconds. I have had this once where the ram went faulty and the system ended up needing new RAM but I think this is extremely rare especially in your case.

Hi there,

I want you to try something next time this happens, instead of rebooting the computer, just cut power to the monitor. Then switch it back on.

Does the screen come back up?

Comment back and let me know

Unresponsive keyboard + mouse pad


I guess you have a mechanical problem, sounds like the mother board have some issues on starting all devices.

If you could use keyboard to go in the bios, and see the screen, if would be the OS that need to be repaired.

Screen goes to sleep after "no signal" message


If you do not move the mouse or press any key on the keyboard it could be just going into video power save. Confirm it by moving the mouse or pressing a key on the keyboard. If the monitor comes back on, adjust the power settings in control panel and change the time for the "turn off display" to a more suitable setting.

Power Saver not working


The Logitech wireless keyboard "moon" key set the power saver on but would not return the screen no mater what key I hit. So, I connected a standard wired keyboard and hit the space bar. Once returned I disabled the "moon" key though the Logitech software.
