I recently but windows 7 on my computer, its was working great for about 2 months. Yesterday my computer started to lag alot so i checked if it was windows 7, i reset the computer but i still had the lag so i checked if anything was overheating, and it said fan 1 was overheating - im guessing thats the one for the processor since its the only one with the rpm - i opened up my computer pushed the fan in a little bit and it stopped overheating (i think my computer internal temperature was to hot), now when i try to use my computer it lags alot and according to the cpu guage its not overworking, is there anyway to check if my cpu was damaged?
