Desktop computer screen is black but you can see the mouse

The screen is black but you can see the mouse move. If you hit control alt delete you can see that screen, select a user and it goes black again. The computer is a year old. My thought was an inverter because I had to replace my laptop when it went out but that was a totally black screen all the time. Any suggestions?

Just occurred to me--

Does your desktop computer have more than one video monitor port?  If so, have you tried connecting your monitor to the other port?

If your system has multiple monitor ports, then you may have inadvertently connected to the "secondary" port, and Windows may be displaying the "primary" screen with start menu or start screen on the unused port.  Moving the connection should solve this issue.

If you can see the mouse cursor and the Ctrl-Alt-Del screen, then this does not sound like a hardware problem at all.  Much more likely to be an OS problem.  What OS are you running?

Hi Artismobile,

I would recommend You go on CTRL+ALT+DEL and then open task manager and click on "New Task" and type in explorer. I guess that explorer is not running like it should. Otherwise You wouldn't see mouse point.

After that You need to go on event viewer and take a look/scan for viruses(malwares).

Thanks,

D.

No good monitor is out...and lets leave hardware out of the equation
Simplest technique would be to use system recovery..given win 8 or 8.1 ...see this page for instructions on how to access for win 8 or 8.1...
http://pcsupport.about.com/od/windows-8/a/open-advanced-startup-options-windows-8.htm    ..this covers options for both
If system restore has been enabled I would start there..and get behind the corrupted driver etc.
Several other post on this issue have pointed to that solution

Looks like a loose port. Powered off the monitor, back on computer off back on and it's working. I'll re post if it happens again
