Random BSODs and restarts while idle

Recently my computer has started restarting itself and/or crashing when not in use. As long as I have something active and in use, like a youtube video or a game running, it will not crash or restart at all; it only restarts when I leave it idle. For example, just now I left my computer alone for a half hour to make food, and when I came back, it had restarted and a new dump file was made (1/5/2018). I know it isn't a heat issue, both my GPU and CPU barely go above 50C even in use, and my memory usually stays below 40%.
Here's the zip for all my recent dump files.

Hello ubuu,

Welcome to TenForums :)

The most recent crash (today) was recorded as a 0x124 bugcheck (hardware error). Earlier crashes were for different causes; the one on 2 Jan was possibly memory corruption, the previous one was due to a critical process that died but there was no information as to the cause.

With this background I am going to suggest you run a series of diagnostic checks on your hardware. Please report back on the results.

STOP 0x124 Troubleshooting

Read carefully before proceeding.

   Warning

If you're overclocking your system, revert back to stock clocks now.

   Note

Test the system once the overclock is removed before continuing with the steps outlined below.

Part One: CPU Stress Test
Part Two: MemTest86+ RAM Diagnostic
Part Three: Hard Drive Diagnostics
Part Four: GPU Stress Test

ONE

 CPU TEST

Run Prime95 to stress test your CPU. Prime95 - Stress Test Your CPU - Windows 10 Forums

   Warning

Your CPU temperatures will rise quickly while under this stress test. Keep a keen eye on them and abort the test if overheating occurs (keep temps below 85°C).

TWO

 RAM TEST

Run MemTest86+ to analyse your RAM. MemTest86+ - Test RAM - Windows 10 Forums

   Note

MemTest86+ needs to be run for at least 8 passes for conclusive results. Set it running before you go to bed and leave it overnight or longer. We're looking for zero errors here. Even a single error will indicate RAM failure.

THREE

 HDD TEST

Run HDTune to

• check the health,
• scan for errors, no quick scan but full scan
• run a benchmark.

It may take some time, but please take the time you need to perform it properly.
When above is done please make screenshots of the following

• the health,
• the error scan,
• the benchmark incl. following
  
  • transfer rate,
  • access time,
  • burst rate,
  • cpu usage.

FOUR

 GPU TEST

Run Furmark to stress test your GPU. FurMark - GPU Stress Test - Windows 10 Forums

   Note

Run Furmark for around 30 minutes.

   Warning

Your GPU temperatures will rise quickly while Furmark is running. Keep a keen eye on them and abort the test if overheating occurs (keep temps below 85°C).

I ran all four tests, as well as chkdsk and the standard windows memory diagnostic and perfmon. All of them came back fine, I would attack the perfmon report but html attachments aren't allowed.
