Solved The screen turns into green pixelated noise

[Frikster]

Hello
Today i cleaned my PC case with compressed air , a TON of dust came out of it and the temperatures were great but i noticed it was acting a bit slower than usual. I didn't think too much of it since its an older pc and i don't expect it to be any good. I started up a game and after 10 minutes i started seeing white noise on my screen... the type of noise you see when something is interfering with a signal. I saved my game, closed it and went into detective mode. The temperatures and ram usage were fine but i was still getting the lines showing up and after a while they turned into (around) 4x4 pixels width.
Rebooted and everything seemed fine. Went into youtube, and after around 5 minutes of playing a song i decided to change it, i clicked my mouse, it froze into place for a second and my whole screen turned into green pixels with other colored pixels mixed . Restarting the PC seems to fix the problem, temporally. During video and gaming the temperatures are in normal boundaries. I got a few BSODs which i haven't seen in a while ....

Any ideas ? If you need any info please ask and if this is the wrong section then can it please be moved. Thank you

edit: My GPU has the latest drivers installed. This problem did NOT exist before i did the cleaning. I had 60 degrees celsius from the dust, now everything runs below 40, with CPU being at 27 and gpu at 35.

Hi

first thing I would do is open the case power removed. and reseat the graphics card and ram and make sure all conectors are seated all the way.

shut down computer unplug computer from wall. open side of case and take out the graphics card and put back in same for the ram. and make sure all cables are firmly in place. could even unplug cables and put back in to make sure they are seated all the way.
