Thanks guy's with your help, I finally got off my ass and opened my computer,it was'nt that dusty inside however I did find that the CPU fan was running intermittedly, so I went into bios and changed the fan speed from lagacy to disable, so now the fan run's all the time instead of off and on. I also found that one of my fans was not working at all? the dips at comp USA did'nt even run any power to it??? I should of did a better job of checking there work after I got machine back home!
