Hi everyone. I know there a lot of technologically gifted people on this forum so I figured this would be a good place to start looking for a solution =). Anyways.. Quick background story. I purchased my computer new about a year and a half ago. I don;t have any experience actually assembling the hardware, so I let the techies at the website do it for me. The rough specs include a quad core, 4gb ram (ddr2 i think), GTX 280 (stock), and fans, power supply, etc. Ill grab the exact specs when I get home. Anyway, a few months ago, my computer crashed out of nowhere ( as soon as I logged in I was met with a pink green and blue pixelated screen that I later found out was graphics corruption. My computer guy told me the config files for vista were corrupted something, so $170, win7, and two months later, I had my baby back. Unfortunately, now the fan on the side of the computer ( I have one on the side, one in back, and a large on the front) near the gpu stopped functioning, and only spun intermittently with a squeaking noise, and now barely moves at all. I figured that with two other fans I could do without. I was wrong though. I can play less graphically intensive games like an older splinter cell, but when I load up crysis ( a game my computer was able to spank at max settings not a few months ago), i can get through the start menu, through the first cutscene, and past the first load scree, but as soon as I initiate the actual game, it freezes, and crashes. I put a widget on my desktop to tell me the temp of the gpu, and I get a reading of 73 c after the computer crashes. Just idle it reads ~50c. Now the latest trick the computer decided to pull was the same scary graphic corruption (pink and blue and green pixels) when I tried Left 4 Dead at max settings. A hard reboot fixed it, but Im terrified of running programs until I get the problem sorted out. I live in a high dust enviroment (arizona) with a few large and hairy dogs that just attract dust, so I'm curious if a dust buildup along with the shifting of the computer when I was transporting it is what nis causing the problems. Any other ideas? thanks to any who even take the time to read this.
