Ok so, i start by saying that i'm no hardware guru and I have just basic knowledge of how a pc works.
The 1st issues with the graphic card arose about 4 months ago with over-heating issues, i have an Asus Nvidia GTX 260. What was happening basically is when i run (or attempt to run) high-end games like crysis 2, skyrim starcraft II (you might be thinking that these arent high-end at all, but my pc is about 3-4 years old) I would play the game decently for about 10-15 minutes, than the screen freezes for about 1 min, and than it becomes functional again with the textures all messed up on my screen (for example, instead of seeing rain droplets i was getting rain squares, the npc's model were getting messed up, etc.).
I deduced that it was an over-heating problem, so i took the pc apart, cleaned it up, removed ALOT of dust from the GPU fan, and that seemed to fix it, i kept doing this like once every 2 weeks and it seemed to hold up.
Now to yesterdays meltdown, i was running football manager 2013, which is not as demanding, and during a match the screen just froze up again and didnt regain function, so after waiting 5 mins I manually restarted, it took a very long time to boot and when it did boot up i got 1 long beep and 3 short beeps, the pc starting booting. Now here comes the fun, you know that when you switch on the computer you get the image of your motherboard make (for mine its Asus p5q Pro with a blue background) the image had horizontal thin green lines spread all across the image, it happened even for the windows loading screen, and finally it loaded windows normally (or so i thought). I tried to open firefox and as soon as the firefox window opened the screen froze again, after about 1 min it came back, I minimized firefox and opened my computer, it froze again, I noticed that as soon as the computer 'senses' a visual change (opening of a new window, resizing a new window, loading a webpage)it froze, after about 5 minutes of this i got an 'nv4.dll' error, something about a corrupted driver file, i can't remember the exact name of the file only that it started with nv4. I completely removed the drivers and tried to re-install (in safe mode), and for some reason the system isn't 'accepting' the driver installation and it keeps booting up on a 1024x768 res just as if i had no gfx drivers installed (and i keep having those horizontal green lines at the start).
When i go to rightclick->properties->settings under the display i have 'default monitor', than when i go to advanced->adapter the chip type, dac type etc. are all marked as unavailable.
I looked around for similar issues before opening this thread, and I got a little confused because it might be my motherboard and/or my graphics card, or the psu, so i opened this thread to get some opinions before i start taking my pc apart and test around to see which is the actual problem.
thanks in advance for any help!
