"but after installing every computer parts it was dead set... "
What does this mean. Was the computer dead and not booting or was it dead set on doing something that you did not post?
I am not trying to be rude I just need to make sure I understand what is going on. Don't want to lose something in translation so to speak.
yes it was not booting before...but actually it is now functioning well,... i already installed the cpu fan back, without reapplying a thermal paste,... so i'm just worried if my cpu will overheat because i didn't applied again
