Vertical Lines

[Norberto1]

It was a friday in the morning, i waked up and I proceeded to get into my Class (Programming) Then I played Lol for quite a time with a friend. Got tired, and I let my computer in the desktop view with no programs open. I took a shower I when I returned to my computer the screen was flickering. Which surprised me. 
I got a bit scared, so I turn off my computer n went to a Local party. The next day I turned on my computer and everything seem to be normal. But after a few seconds the screen turned into changing vertical colored lines. 
Sometimes I get to see a black background, with black squares. My English is not the best. 
And I live in mex. 

 

Something important to mention, is that when I plugged the computer into the tv, everything seems to be just fine.  

I updated the graphics card along with the bios. It did not worked.
