Recently I got a EVGA nivida gtx 680 sc as a graduation present. I installed it and everything looked great. I started playing games on it and everything was fine for the first few days. Temps were great (I have 6 fans total in my case). On the third day, I was playing BF3 for a few hours. Everything looked good, as soon as I turned the game off I started getting green artifacts and then my computer crashed. It said the driver stopped responding. In response, I uninstalled the drivers and downloaded new ones directly from Nvidia. I started playing again, everything was fine. But then as soon as I turned the game off my computer would crash, wouldnt even recover. I started thinking that maybe my bios was causing it because I was OC my cpu. Reset my bios to normal, still same thing was happening. I then decided to run a GPU stress test, this is where things got ugly. I ran furmark for 30 min. It ran beautifully. Temps were good, fps was great. It ran the full 30 min. As soon as the testing ended and I closed the program, my screen went red and my computer crashed. After that I started getting the artifacts on boot up, even before post or bios. I then decided to reseed my video card, I reseeded it, then all of a sudden my computer wouldnt even boot. It would come to a black screen with a blinking cursor. It wouldnt even post or let me go to bios. I tried putting in a old video card, got the same thing. I then tried resetting the bios by taking out the cmos battery, still got nothing. The first thing I did was make sure the video card was toast. I took it to a friends house and sure enough it was fried. Was getting green pixels all over on his computer. Sucky thing is the guy who bought it got it from Frys and there is no frys around where I live and I can only return it in store =/ Hopefully EVGA is good with RMAs.
Now back to the other issues. I then wanted to figure out what else was wrong with my computer. I took my motherboard out and ran some tests on it. I got a speaker from a friend to install on the motherboard to hear the beeps. I first started with no ram, it did the corresponding beeps. I then put ram in but no video card. My manual says it should beep if there is no VGA detection and I was getting nothing. I then put a spare video card in to see if it would beep for no keyboard, got nothing. So this I guess is where I need some help. Am I right to say my video card is gone? Also, what could have caused this? I was thinking maybe my PS was crap. I do have a 700w PS but its like one of those cheap ones with a brand no one has ever heard of. If the motherboard is fried, then it leads to a whole new topic. The CPU I have in there is a Intel Core i7-930 Bloomfield 2.8GHz LGA 1366 130W Quad-Core Desktop Processor BX80601930. The socket for that is 1366. I looked on newegg and there are only like 6 motherboards with a 1366 and they all seem pretty expensive for a motherboard. I was hoping someone could share some enlightenment on my situation. I appreciate any help.
