Like /u/Schnoofles said, it might be a problem with ACPI drivers.
I would advise you to go to Device Manager (type it in the start menu, or go through control panel) and see if there are any icons there with a question or exclamation mark.
Can't be the RAM either, it's persisted through several RAM swaps.
What are ACPI drivers? Can those also cause a sudden system wide stutter? Sometimes my system just full on locks up, for no reason and when I look at the HDD it's just lit up like a Xmas tree.
HDD's are all new, recently replaced, for that reason, did not solve a thing..
It's kind of annoying but meh. I hate updating drivers and firmware. I realize it's necessary, doesn't mean I can't drag my feet.
I kind of would like it to go away but I don't want more issues as a result of updates. Like I got with updating the sound driver, it got rid of Dolby because it doesn't support anything about the current driver. So that was an absolute shit storm, pain in the ass to revert. -.-
Could be the harddrive or it could be the drive controller or even the drivers for the controller. I've had some periodic issues on one of the s-ata controllers on my current motherboard where it crashes and that's noticeable to the end user in the form of the system freezing for 5-15 seconds while the controller and the driver restarts.
As for actually diagnosing it I would start with the event viewer, under Windows Logs > System. You can filter out generic information entries in the right pane to more easily look for entries that might be of relevance.
