Hey all so here's what i am going through. I have a mac book using window7 on it from months and months ... never had any kind of problem. From last 3 weeks i started getting back lights shutoff and finally i sorted it out as i see win7 causing high CPU usage almost 90 to 100% so i get back on xp about a week ago and back light issue was sorted. Then after a day or so i started getting sudden system shutdown I installed few programs and figured out cpu heating issue which is 65 to 70c all the times. I changed some fan setting but mini i can get is 62c(though i live in a very airy place and outside temp is 25). From last 2 days system shutting has just became a pain in a** but system is keep on shutting after every mint. Yesterday I just opened the whole thing and cleaned it from heat sink to mobo thinking there might be some loose wire or heat sink maybe but what i did wrong i cleaned the whole artic silver compund thinking its a rust or some bad stuff. Now i am badly in need of help please please let me know how i can troubleshoot this issue. Its just keep on shutting every 2nd mint. I have reinstalled xp vista win7 like 100z times no help.

BUT SYSTEM DOESN'T SHUT IN SAFE MODE and works perfect If that could help.

Please guys i badly need help. What other reasons could be?

It's macbook 13 using intel dual core duo (just a note from last 5 or 6 months never had any kind of problem just started about weeks ago)

Please advise and thanks for taking time and reading such long post. Will really really appreciate some help ..


Regards

Sunny

You said you cleaned off the thermal paste. Did you reapply thermal paste before you put it back together? If not, then that is what your problem is.
 
No i didn't as i dont have it .. will buy and re apply... btw is there a way to tell if heatsinker isn't dead.. coz i am suspecting on heat sinker... please advise..
 
Like said, you need to replace the compound if you didnt. As far as the heatsink, its just a hunk of metal, cant go bad. Now the fan on top is a different story. Is there some reason you think the fan isnt working.
 
The Good News: Thermal paste is cheap, it shouldn't cost you more than $10.

The Bad News: Your computer will likely continue to not work properly until you reapply thermal paste.

How to apply thermal paste.
Place a small amount on the processor when applying. (A little goes a long way!) Put a thermal paste dab the size of a grain of rice in the center of the processor. Gently place the heat sink over it and lock it into place very carefully. The pressure from it being locked will spread the dab you placed evenly over the core of the Central Processing Units heat-shield.
