My pc fails to start

[ChatIndia]

I have reinstalled my heatsink and now my system shut down automatically after 4-5 sec. What should i do

[Gouri]

It is probably because of heat, Check whether the heat sink is properly installed or not. Generally when ever you remove the heat sink it is advised to re apply the thermal paste.

Don't you see anything on the screen when it boots? Does the PC Beep at all?

And if you have meddled with the processor check if it was reinstalled correctly, and make sure you do apply thermal paste, if you don't it could lead to your processor heating up more than it should do which will cause irreversible damage,

I've not applied thermal paste and every thing seems normal for first few sec and then it shut down.

[The Real Rebel]

did you check the processer? and if on the heatsink metal prongs holding the heat sink in pace or anything metal make sure its not touching the mobo, since it will short and could cause what is happening.

What happens when i won't connect cable to mobo cause while removing the cables i have pulled it so hardly.

ermm it should have broke, but I'd say your best bet is to go to a repair store and get it looked at because I can't really see a problem LOL!
