Lots of programs "have stopped working". Also glitchy screen.

An issue came up on my comp recently, and it's the "x program has stopped working, windows is trying to find a solution", this happens randomly when I'm playing games like League of Legends or Final Fantasy 14, it even happens to Skype, and most importantly, sometimes it happens to Windows Explorer saying that "Windows Explorer has stopped working and will now restart". I don't know what is causing this and why some programs just decide to give me that error message. Is it my graphics card? Is it because I have malwarebytes and MSE?
I don't know.

I sent in my comp to my tech place to solve BSOD's and they returned it, said it was working fine, but it clearly isn't if these programs randomly give me the "stopped working" error. I think we all know which error we're talking about right?

There's another thing, and I think it's graphics card related, sometimes I see little glitches on my screen randomly, as if something was wrong with the computer, like little color glitches, maybe a little black bar in a random place, or a "glitchy" color bar somewhere. Is this because my graphics card is too old now for this CPU? I have another graphics card, which is gtx 680, but it's sent in for repair because the cooler on it stopped working and should be returned next week.

Does anyone know how to fix my "x program has stopped working" problem? Is it video card related? Is there something on my computer that's causing it? Maybe having 2 antiviruses? Is there malware on my computer or something? It gets really annoying.

Help would be very much appreciated. I attached my dxdiag if that helps.

edit: This is what the "glitchy" random screen I'm talking about: http://puu.sh/bxEUW.png that's part of a website, and sometimes it gives me those bars. ALSO I forgot to mention, if I leave my computer on for too long, white specs will cover my entire screen no matter if I'm gaming or just browsing tumblr/facebook, just imagine something like snow all over your screen. I assume this is a video card thing. So I have to restart sometimes and it fixes itself. But my major problem is the programs that randomly "stopped working".

An example of the "stopped working" error: http://puu.sh/bxFeC.png just googled it.
I also get "COM Surrogate has stopped working" a lot, too: http://puu.sh/bxFkH.jpg and usually when I puu.sh things (it's an application that lets you take screenshots of your computer and upload it quickly) or when I open up picture files.

No, I have not recieved a BSOD once since the tech company gave back my comp, to run "tests" and fix things. The BSOD's I got were all graphic driver related, you know, nvlddmkm.sys stuff, everything related to Nvidia. I got my comp back on monday and now it's saturday. Usually I would bsod at least once a day.

The piece of crap tech company I'm talking about sold me my comp with lots of issues, like corrupt RAM, my gtx 680 video card not being supported by the power supply, etc. And it's still taking over a year to fix all this. The corrupt RAM issue was fixed, by trying 19819238 RAM sticks, and they wouldn't work together alone, so I had to settle with 1 RAM stack of 8gb when I ordered 2 of 4gb. So the RAM problem is fixed, but the cooler on my gtx 680 card stopped working and it's sent in for repair because they gave me a power supply that did not support it, so just NOW that they gave me a higher power supply.

I edited my main post, btw.

Sorry I'm not very familiar with computers, I don't know what you mean by "monitor the temps", I have a temperature monitor program, HWMonitor, that I used to monitor my graphic card's temperature when the fan wasn't spinning. What would you like me to monitor?

I'm not sure about damaged hardware.

Hey, I attached the monitoring data.
I also took a screenshot: http://puu.sh/bxJrW.png if it helps to actually see the temps.

I don't know what you mean by "When the fan wasnt spinning?", the fan wasn't spinning, so obviously the temp got too high and shutdown the comp. I'm using a 9800 GT nvidia card right now, my old one, my gtx 680 is out for repair, the one where the fan stopped working.

Well, looks like I got my first BSOD... guess I should make a thread, sigh.

edit: I made the thread: dxgkrnl.sys and ntoskrnl.exe+75bc0 BSOD, help please? I don't know if I should delete this one or not.
