I suppose it would have helped to fill you in on all that. Yes it is very clean and dust free, all the components. It came with paste, I removed it to test my CPU in another computer and put new heat sink compound on after cleaning off the old stuff as soon as I got it home. All fans work and are clean. The problem first only occurred when I was in a full-screen game but then it started to occur outside of game.
Also I would like to say I swapped out graphics cards to a smaller, lower quality one and swapped my RAM slots to see if I got any errors there. I bought 2 fans (a 25 CM fan for above the graphics card and a PCI slot fan for below the graphics card) UNFORTUNATELY before I could install them it really got hot and shut down for what seemed like a last hoorah and hasn't been the same since
