Hi, my Gateway 7322GZ runs hot and crashes frequently. I intend to clean the heat sink, fan, and re-apply thermal gel. I have opened the machine from the top to expose components. Not sure what to do next ... I have had no success with finding a disassembly guide for this type of laptop. I am trying to generalize from steps related to other machines but this one looks different than those and I'm not sure what to do next. Any thoughts?

The CPU Heat sink (the big metal block with a fan) may not be making good contact with the CPU surface area.
Thermal compound may have not been applied between the CPU surface area and heat sink
The heat sink and fan are not sufficient enough to cool your CPU
Dust buildup is not allowing proper circulation of cooling air
If this system is not a name brand and covered by warranty then I would remove the heat sink (carefully) and verify that the mounting bracket is not broken or loose. I would check that ample thermal compound is applied, and if not use rubbing alcohol to remove all compound from the heat sink and CPU and purchase a tube of compound to apply yourself. I would also thoroughly clean the heat sink with compressed air.
If the heat issue continues then you will want to consider upgrading to a more powerful cooling solution.
The CPU fan should run constantly but in some systems will run between 50% and 100% speeds assuming a variable temperature control is applied to the system via motherboard or third party installation.
The only thing that you did not mention was fresh conductive thermal grease compound, did you take the heat sink off the processor ic and remove the old thermal compound? if you have not done this you will need to complete the repairs and apply fresh conductive thermal compound this will dissipate up to 50% of the heat and should solve your problem. If this fails you need to make sure the processor cooling fan is running properly, or the processor ic may need to be changed because of thermal runner way.
The fan may be running too slow (faulty bearing) or the fan and heat sink assembly may be clogged with dust.
Check the CPU fan to see if it spinsfreely, if not replace the fan.
If the fan and heat sink is clogged withdust the remove the dust and make sure the vents are clear and dust free. Use acan of compressed air to do this.
The cpu processor is getting to hot, check to make sure the cpu fan is working properly, if it is then the laptop must be taken apart. Chances are it is dirty and needs cleaning, the heat sink should be removed from the cpu for cleaning out the old conductive thermal grease and new applied. If the cpu fan is not functioning it must be replaced.
clean the cpu cooler slots and replace the thermal compound on the cpu ....make sure you clean off the old thermal compound .....only a thin layer of new thermal C will do all most see through ... hope this helps my friend
You can find professional cleaning solution products at any good computer parts store, or you can rubbing alchohol (the less water content the better) use a lint free cloth like the kind to clean eye glasses.
It sounds like a thermal shut down when the processor over heats,one thing it might be is that the heat sink is not seated properly on the processor.When removing the heat sink make sure you have thermal paste to place between the processor and heat sink.That should give you a good starting point.
How many HDDs/internal devices are you running off *********** board? If you have an AMD processor, they tend to run hot too. If your computer is running agonizingly slow or shutting down by itself, I would suggest you do the following:
Take your heat sink off your CPU and clean off the heat sink paste and re-applying. If you haven't done this before, you only need to put it on in a VERY light film so you can partly see through it. Applying too much can cause over heating.
