I already did ll that. Im going to state my whole story as it might help out. Because i haven't gotten an answer yet only questions.

i'm sorry if im repeating things but as you can imagine im feeling so bad right now its not even funny... Joshua i'll try and explain in detail but if theres anything, i mean anything you need to know tell me and i;ll find out.. Okay it was working perfectly till i download 2moons, found a trojan got rid of it with Avg, after about 5 scans of just cookies there was nothing anymore. I tried to download Runes of Magic overnight i come home from school and find the download stopped at 1.4gb and all the temps were fine. I try it again the next night come home and it stopped 9 minutes short at 3.8/3.804Gb or something like that.. So itried to download Crysis Patch+ fear this time and when i come home and i find the computer off.So next day try todownload onlythe Crysis Patch(from ea download manager)I turn on the computer and it wouldn't turn on. Somehow it started after 10 minutes i looked inside the case, cpu fan and Gpu fan weren't runing i didn;t know what was going on. I tried to tighten every possible cord in there, and i took out the heatsink and saw paste and that the cpu looked fine and not burned. And there was no funny smell. I put it on and the Pushpins were driving me crazy ( not sure if i installed it correctly). I turn on the computer and i find 2 red lights on the Gpu and my motherboard lights that are usually on has like 4-6 different ones with diff colors red,green,yellow idk what else were off.. Turned it off immediatly, tighetn the psu cord to it and turn it on and everything is running ( with all the lights on the motherboard). I look at temps and The Gpu is stable and all of a sudden the Cpu jumped to about 68C or something like that and it was at startup. I immediatly Turned off the computer And now im waitting for responses on what to do. My specs are Gigabyte P45,Wd 320gb Harddrive, 4gb Corsair XMs2, Intell Q9400(stock fan), Xfx hd4890, Corsair 750TxPSUand CM690. IF you guYS nEeD ANY INFO JUST ASK AND I WILL FIND OUT.

Edit #1 : Here are some pics i got on my last boot up - http://img4.imageshack.us/gal.php?g=p1010309m.jpg.. I also added some ino to my story. That's everything that happened and im 95% sure thats the order i might of screwed up the order of something since this has happened over the last 4-5 days,

Edit #2: Forgot to say i also replugged the video card after taking out. ( This happened right before i reinstalled the heatsink the second time.

EDIT #3. I forgot to say something tht happend. Idon't remember i think this was when the comp wouldn't turn on and i oppened it up. I tighteed something and all of a sudden in a couple secs i see the psu fan and the blue led front fan(and liht up)move about 720 degrees and stop andrepeat till i unplugged the psu i think it was. Also added my psu and my case.( not to confuse anyone i meant add them to my specs above). On the day i tried downloading the Crysis Patch i also got a Windows Update trying to install a Malicious Removal Tool and i installed it.
