|Have you tried another PS/2 mouse, some computer shops still sell them?|
If the processor OVERHEATED then the computer would TURN OFF without warning unless you computer is really OLD.
Don't take the heatsink off unless you know what you are doing, don't try to be clever and take both the heatsink and the CPU out then come back and complain that you,ve got bent pins or something.
You put the fan against the HEATSINK, the piece of metal with a little fan on it , the CPU is a little square chip that processes instructions and is underneath the big piece of metal with a fan on it.
Plus if you take off the heat sink you MUST reapply the thermal paste- http://www.techpowerup.com/printart...
And can you type properly as it is hard for me to understand what your are saying as i don't type in slang and cut sentences so that they don't make sense.
I am a hardware guy not a software guy but i try to help.
