I'm at a loss for this one.
So the machine I work at has been upset ever since it had a number of power interruptions hit it while it was running almost a year ago and nuked two cheap sticks of ram. After those were replaced and certified by Memtest the machine continued to run fine......but files would corrupt or the system would crash and give absurd errors. More confusing yet was that files that had clearly become corrupt (or Windows flagged that they had become corrupt and I should run chkdsk) reverted back to being untouched after a reboot (or a bluescreen which forced a reboot). The system doesn't keep shadow copies of files so once it's corrupt I would expect it to stay that way.
Anyways, here's an example. I took a photograph a few days ago and left it on the desktop. I came back to it yesterday morning and it looked like this:

Ruined. I knew for a fact it was fine the night before. Like I said however obviously corrupted files magically revert back on a reboot so I did exactly that and opened the image again:

Totally fine. I'm baffled. If it was an infection (and a scan says it's not) I'd expect the file to be permanently destroyed.
Is there still some other ram sticks that haven't been replaced?
There's two others but with memtest passing there's no point blaming the ram.

Memtest is not the be all and end all.
Having said that, it doesn't seem like a RAM issue. Maybe the drive controller (SATA, IDE?), or drive cache?
