1 - verify that the CPU fan is running when the computer is working. Some systems have temp controlled fans, so you may have to wait for it to warm up before you can tell it's running. If you're not sure, run Prime95 to stress the CPU and that should kick it on.
Fan is running
2 - use a can of air to blow out the fan(s) - for a laptop, blow in both directions (but don't overspin the fan when doing this)
Fan is cleaned
3 - test the hard drive using a manufacturer's diagnostic
Drives passed diagnostic tests. Ran the Western Digital extended diagnostic on my 250GB boot drive and the SMART scan on a recently installed 1TB storage drive. The issue predates the installation of the 1TB drive but I tested it anyway for good measure.
4 - test the memory (I recommend MemTest86, but the Vista memory test is just as good).
Ran the Windows Memory Diagnostic Tool per your initial instructions and passed. Please let me know if there is a different Vista memory test I should try.
5 - test the motherboard. Motherboard test suites are usually too expensive for normal users ($800 US and up), but this free program may help if you can get into Windows to install it:
