The random crash also may be caused by electrolytic capacitors going bad, this happens when they age, but much more quickly in a very hot environment. Take a look at your motherboard as see if this may be the issue as seen in this video:
Thanks for the help, Idealab.
It's a laptop, and according to the different forums these laptops are known to run at high temperatures (about 60° C); mine runs even much higher, as I mentioned. In general, it appears the typical high temperatures for this type of laptop is caused by a double flaw:
1. the ventilation openings being not ideally located or insufficiently large for the heaviest processors that this laptop can run, and which produce more heat than less powerful processors.
2. apparently the heat sink in these laptops is separated from the CPU and therefore does not optimally guide heat to the fan. So even with lots of thermal paste, there is still too much space.
The only way I can promptly reduced CPU temperature is by unplugging it and running it on battery. Temperature then instantaneously drops by about 20°C. I am not sure why that is, but evidently some processes (defrag, and others) only automatically run when plugged in, and I am sure that that several of the mysterious Windows' "System Idle Processes" also only run when plugged in.
For the rest I think that only external ventilators might be able to reduced the CPU temperature, or modifying and rebuilding the heat sink. There even seems to be a "1 penny solution" where they literally put a penny or a cent in between the heatsink and CPU, which apparently ensures that there is contact between the two. I have not tried that out for the simple reason that I fear that the coin could slip out and make contact between two other structures and produce a short, which would be even worse.
