My laptop seemed to work fine untill now, i am experiencing the infamous blue screen syndrome. The laptop heats up rapidly and it shuts down automatically after running for 30 to 40 mins, I am experiencing this problem for quite some time now, there was no change even after using a colling pad.

Please advise..!!

Some other specs? Linke OS running on it? What you've tried up to now to repair it?

If you know what you are doing, dismantle it and get all of the dust out of the cooling system. If you don't know how to do it then you need to find someone that does.

I will try it out.Thanks

also what is the make and model of the laptop

Oiling the fan's bearing is a good idea while you are in there. We use fully synthetic motor oil at work and it does a fantastic job.
