White Horizontal Lines (Display Problem)

It was a normal day with me playing Counter Strike Global Offensive . Suddenly my monitor went in all colors .Like alot of pixels and my game got laggy .Then when i exit the game . My GPU *video card* crushed . Now all i see in my desktop is white lines everywhere . What can i do ? I tried to clean my video card and reinstall it but nothing happens .
Also if i go to advance settings from screen resolution , i can't see the adapter name or anything from there. It's blank

Mate some system specs would be good but this sounds like a GPU or a monitor issue to me - so is the machine booting into anything at all? apart from this white mess.

Startup Repair

What you could do is check the cables to the monitor and maybe the monitor itself is not that good can you try another one?

When you say the GPU crashed just what do you mean - burnt or what??

On thinking about this it could also be a power supply problem but let's see what you have first.

Ok mate just replace the card for starters if that was the message but now is a good time to check out all the components monitor, cables, power/reset leads to the board and all the crud cleaned out too etc etc

Sorry ;ate reply mate - broadband problems. Now new/different GPU, monitor, and cable and no change is pointing towards either the PSU or worse the board and some system specs would be good please to see what we are working with.
