Try another monitor.  If that doesn't work reinstall your video drivers with control panel system device manager.

My Hp-620 Laptop is not displaying Wallpaper and no option for it pls help me


Do you mean your laptop shows no start menu, no desktop icons? If its seems like it booted up except nothing is shown on the screen try the steps below.

Click Ctrl+Alt+Del to get to Task Manager. Hold the Ctrl key, plus Hold the Alt Key then hit the Del key while holding them. Once the task manager opens Clcik the Processes tab then click the Image Name Column heading on the left to get them in alphabetical order. Scroll down and look for explorer.exe. If you see it click it to highlight it then click End Process.

Next, click the FILE tab at the very top left of the window and select New Task (RUN). When the Create New Task window opens type explorer.exe and press ok. Your start menu, task bar and desktop icons will start appearing and populating. if not that means a virus has hidden your files and folders.

If it is not resolved try the steps below:


Shine a flashlight on the dark screen to see if you barely see the icons on the desktop. If so, then the LCD Inverter is bad.

Plug in an external monitor and see if the display shows up on it. It can be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If so that proves your video card is ok. The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.

If you see no icons by shinning a flash light and the external monitor works, then your screen is bad. If you see no icons by shinning the flash light and nothing shows on the external monitor, then most likely your video card is bad.

The monitor comes on each time but then goes dark after a few seconds


i think u r using window 7 or vista.
this happens when ur system is infected by virus.
so, you may try this trick....

Note:- If you have multiple user accounts or your account is password protected then start from Step-1 else skip Step-1 and Directly follow step-2 instructon

***** Step-1 ****
press ::
ctrl + shift + esc
or
ctrl +alt+ delele

then you will see a screen containing some menu such as "Start Task Manger", "Switch User" etc....
if u have ur account password protected... then select "Switch user"...Enter password and press enter..

if again screen become black,,,
then do step 2

***** Step-2 ****
press ::
ctrl + shift + esc
or
ctrl +alt+ delele

select "Start Task manager". then do this: File>New Task(Run..)
Type this coomand:

explorer.exe
and click Ok.

Now u can back up your important data and files.
Install new windows operating system if Anti virus fails to Detect the virus and fails to repair the system.

Hp dl380 G3 no display on screen.


if you mean that just shows a bue screen and no task bar or desktop ..this is probably from a virus attack that cause it ..Try to press ctrl+alt+del this should show the task manager and in the task manager run a new tas ...and lunch the windows explorer again ..
or just run from task manager the system restore..and try to restore it to an earlier date that worked..To do that pres those like I said ..and than in the task manager on screen choose file and new task (run) and type system restore..and hit enter ..ths should run it ...choose the date that you know it worked and run it ..If it do not restore you have to reinstall or ..to use it for the moment find the desktop address and add it in the start-up for that run MSconfig and press enter ..in the start menu ..choose normal ..and enter ..and choose restart ..it should get along well again..

Black Screen when playing 3D games on ATI Radeon 9550 X1050 Serie


the game resolution is not supported by your monitor....this is the reason your screen goes blank....
by the next time if the screen goes blank, press alt+ctrl+del together and check are you able to see the task manager....
if you can see the task manager, then close the game from that window by selecting end task....
if you cant see the task manager, then press ctrl+alt+del together 2 times and check....
if nothing works, then try by checking with any HD monitors if available with you or with your friends...
