Three common problems that cause that:
1. Memory problems.
(The power-on memory-test is crap.)
2. Power-supply problems.
If underpowered, your system can crash when load is applied
either by running drives or heavy computation.
4. Bad caps on a motherboard.
Symptoms same as number 2 above; only the power glitches
are *much* shorter in duration.
Look for bulging electorlytics on the motherboard.

Oops ... Right.
Bad fans, CPU heatsink not mounted right, etc.
Had *one* computer, where somebody at the factory mounted the
Power-Supply fan backwards; so it was blowing hot-air *into* the case
instead of pulling it out. Couldn't figure out why the CPU kept
overheating, no matter how good a fan and heatsink it had.
Bought another (and more efficient) PSU, and the CPU temperature dropped
20 degrees C!

Got a new case with hole in the side to feed the CPU directly from room
air, instead of from inside the case, added a solid-copper "gamer's"
heatsink and fan, used "Arctic Silver" compound on the joint; and the
CPU temperature dropped to about 10 degrees C above case ambient. Quite
a difference for a system that was shutting down every few hours from
overheating. A bit of overkill maybe; when just a ten-degree drop would
have stopped the system crapping out, but ....

yr power suppy failing

Another thing that can cause issues like that is a dying hard drive or
a bad install of windows so check that too
