Today my computer was running fine. I recently tightened the hinges in my laptop screen because it was getting quite loose. Later that day, i opened my graphic properties, i didnt touch any settings, i didnt change anything, i went to 'Adjust image settings with preview' or something like that, and the image had weird checkerd squares tiled all over it.
Please reply, because i am getting worried since this is my only computer and i dont have a lot of money to replace it.

Had the same problem, usually when trying to upscale video ! Try reducing size of video on laptop when using transfer software, see if that helps. With my aged laptop, problem seems to be because my laptop has an extremely slow processor chip, and it just can't keep up with the video !
The software I use, which is free, is Freemake Video Convertor, which gives you a choice of output formats and sizes.
I would try getting the latest video card drivers first, if it is a Nvida card & it has recently updated itself, I would roll back the drivers, there has been a problem with the last update & my computer didn't like the upgrade & blue screened a lot, but was fine after I rolled them back in safe mode, if the problem if not repairable via software then go to a Laptop specialist, for what its worth I think its a software issue as you say its only when playing games, but im not an expert just well informed.

The system is having problems with the graphics drivers, heres how to tell!!! when you first turn the machine on display is clear until it gets to windows. To resolve the problem is quite easy, just reboot into safe mode and un-install the graphics drivers, then reboot. When the system restarts is should re-install the graphics drivers automaticaly for you, job done :)
Unplug and remove the battery pack for safety. DOn't want any shorts to happen. With the laptop open, gently pry with a very small blade the plastic cover at the front of the swivel and remove. It is in two pieces...front and back. It is OK to leave the rear half in place. Once removed you must close the laptop again. You will now have access to the screws on the hinges. Use a small Robertson screwdriver to tighten the screws. Snap the cover back in place....Voila!. IF the screws are broken (like mine were) remove all the good screws, gently lift and move the screen slightly forward, remove the broken screws with some needle nose pliers. Reassemble with new screws. I found some screws at the local computer geek shop in his selection of random screws. THey are quite tiny. CHeck Future Shop if they are in your area as they deal and repair Gateway so you may have a better chance of finding some screws that work. Good Luck.
it looks like the power supply for the light on the lcd screen os disconnected.If you can go deper to dissassemble the laptop you will find the connectors(like small plugs).check all the wires connecting to the screen.
