When i tried to turn on the pc it turned off after few seconds. 1st time i tried it turned after 15 sec off 2nd time 10sec 3rd an 4th after 2sec. It was working fine but in august was 1 time that it restarted for no good reason.

Did you replace the thermal paste on the cooler also? Is the cooler spinning up when you power on? Have you made sure you seated the cooler correctly and that none of the CPU pins are bent/damaged? Sorry for the many questions but need to eliminate the obvious first :)

So you cleaned the thermal past off with vodka and you did not replace the thermal past is that correct?

The way your system is shutting itself down sounds like to me that the thermal overload is being tripped meaning the CPU is getting to hot and shutting down.
You need to make sure you replace the thermal past correctly and that the heat sink is fully seated on the CPU correctly.

You might need to re apply it.

Don't spread it out. The best methods you can do is a pea sized dot in the middle or a half length line of paste centered on the IHS.
