Specs: Windows Vista
It used to click off randomly . Not a normal shut down. Snap or click noise.
Now it clicks off within 1 or 2 sesonds of starting.
Help, Thanks, Paul

Probably a bad power supply.

Hi Paul again
Upon disasembly I found the fan heat sink pluged up with lint.
Would this kill the processor.
The heat sink copper tube runs accross the processor and then to something that looks like a processor. What is it ? could this be dead also?
I am just a hack trying to fix another thing people say to through away.
Just another 700 down the tubes.
Thanks

I didn't google the model number at 1st but I now realize that you're asking about a laptop - you should have said so.

It could be an overheating issue due to the dust/lint clogging the heatsink. Did you physically remove the heatsink or just blow the dust out using compressed air? Do NOT use a vacuum because of the chance of ESD (electro static discharge) that could fry the system. If you did remove the heatsink, it & the top of the CPU need to be cleaned of all traces of the old thermal material, then a fresh dab of thermal paste applied. And it MUST be applied correctly. As for the copper tube that "runs accross the processor and then to something that looks like a processor", it's probably pulling double duty as the CPU cooler AND motherboard chipset cooler.

It's almost impossible to overheat a modern CPU to death. It has buit-in thermal protection features that will shut the system down long before the CPU can fry.

Sorry I did not specify that it is a lap top.
If the CPU has its own thermal protection built in
may be it got tired of shuting off becaces of the lint. and is now just clicking off
with no real heat. I does not stay on long enough to get hot.
1 or 2 seconds. Hard drive spins for these 2 seconds and sounds normal.
A new Intel Cpu is less than $28 on ebay. Its only a guess bub I do not Know what else to try. Runing hot for a long tine may have done it in.

It's not the CPU.
