Are you able to try it on an external monitor?
Looks as though you probably have a bad graphics card/chip. This usually means a new motherboard is needed as most laptops have integrated graphics (i believe your model does).

To connect to an external monitor, connect the monitor using the VGA connector, turn on the laptop and you will probably have to "tell" the laptop its connected to another monitor. On Toshiba this is usually holding down the Fn button and pressing F5.

If you get a good image then your graphics are fine, if you get the same (or similar) output your graphics are shot.
As i said in my previous post, when integrated graphics fail, it usually means a new motherboard. Integrated graphics means, a chip soldered onto the motherboard.

I have connected to external monitor and the picture is same hence my screen is not faulty then if my graphic card is faulty as you mentioned can it be repaired or replaced ? Does my laptop has graphics card embedded in in mother board
Thanks for advice

There is also a possibility that you have a bad memory.

When the video is built in then it uses system memory as video memory so bad memory can cause what you see too.

Try using only one memory and test, Swap and test.

Hi, What I mean is try only one memory and test, if still bad, swap the memories to try with the other memory and test.

If you have a bad memory removing the bad one will make the computer run slow but work.

It is also possible to have built in video and it can have its own memory which could be bad. That is what this test is to determine.

If your is the one with a replaceable video card then finding a replacement may be tough as my quick research indicates that it is one of the ones using a Nvidia video chip that had a dismal track record for longevity.

Still worth trying the memory testing just in case.

Good Luck
Roger
