shutdown automatically

[amar]

I'm using laptop Compaq (Ram 2GB, HDD 500GB, window 7 ultimate). when I want to start operating system. it's gonna spend 2 minutes with me and shutdown automatically. I have tried to boot the system but it disappointing me. I don't have enough time to boot. How to solve this problem ? is there any chances to fix this crucial matter ?

Hello Amar,

So Windows 7 boots... then two minutes later it prepares for a shutdown automatically or the computer just shuts off? If it just shuts off my guess would be its overheating, do you have any software to check the temperatures? Have you recently removed and installed your heatsink?
