reading this made me hurt a little bit...you really need a better pc what did this thing cost you like..280$? to get a pc in nowadays the decent to good range you would need like..triple that plus you never said what rpm your hard drive was running on (im going to assume 7200 the usually normal number but if its 4200 or something ) plus...where is your psu?...or at least the number of fans..
I won't even bother trying to explain what utter shit that build must be. What the fuck were you thinking when you went with c2d and the shittiest gfx cards Nvidia produces? You might have as well gotten an APU.
