Hello everyone, so as the title says I have been having some troubles with my desktop. It started when I was playing MafiaII, when all of a sudden a blue screen came up and said that it was saving memory or something of the sort. This has happened before a couple of times randomly in the past, but all I had to do was restart the system and everything would be peachy keen. So after this happened I went through the normal restarting process, everything was going normally, and then as the windows 7 logo was doing it's crazy startup thing, it froze. This has never happened before, so I tried to restart it again, this time it only runs for about 3 seconds and then shuts down. So now I am stuck in this hole trying to find something to give me a clue as of what the problem is. Here are my specs: EVGA GeForce 7050 nForce 610iQ socket 775, intel core 2 quad Q6700 2.66GHZ, 3GB DDR2-667 memory, ZEROtherm/ CF900 / socket 775 / copper base / heatpipes / CPU cooler. Here is what I tried so far... Bought a new PSU and replace the old one. That didn't do anything, so I brought it back. Took the CPU fan off and replaced the thermal grease. During that process I cleaned out the fan, took out the mobo, and cleaned everything. I also made sure the wiring was correct and that nothing was loose. I've been trying all this with the bare minimals, so I'm not sure what it could be. I checked the RAM aswell so I think that's out as well. So now I come to you guys, I've been searching all day for some solutions but every one seems to have a different solution. Any help is greatly appreciated! I disconnected the 4 pin 12v input to the CPU and it atleast stayed on, nothing happened but the computer didn't turn itself off.. Not to sure what this means.
