RE: Computer switches on but the screen does not show anything

could be a fault with the monitor. could be a fault with the PC
try to borrow another monitor, plug that into your machine and see what happens. If possible also try your monitor on another machine
When you know which is faulty, post again

It sounds as if you have lost all your screen icons. Can you see the menu via the Start button?

The other possibility is that someone/something has changed your desktop to a blank blue screen. Look in Control Panel/Display and make sure the desktop is set as you expect.

Biswas
please in future ask new questions through a new thread rather than restarting old ones
thanks
In this case I am intrigued by your comment that you can play videos and use the Internet through Task Manager. How are you doing this? What progams are you running within Task Manager to do this?

RE: Computer switches on but the screen does not show anything

Biswas, the symptoms you describe occur when Explorer (and I mean Explorer, not Internet Explorer) does not run. You can confirm this by looking at the list of running processes in Task Manager; I think you'll find explorer.exe is not listed.

This is almost always due to a computer malware (i.e. virus or similar) infection, possibly one that has been partially but not completely removed.
