PC Randomly Hardlocks while Gaming, very rarely while not. Peripherals turn off sometimes during hardlock.

Hello all,

So a few months after building my first pc my computer has been hardlocking randomly while playing video games. The time between crashes range from a few days, to everyday, to even 12 hours in between.

Normally when a crash occurs, the crash will become a daily instance until I make an attempt to fix it again. (Such as reseating CPU, Ram, GPU, you name it, I've done it)

I've replaced the PSU, and Motherboard, and these crashes still continue to persist. I've ran MemTest for 30 hours, and not one error. I've stress tested my GPU and CPU, no crashes during the tests, and no errors either. I've ran Diskcheck countless of times, no errors.

I've done a clean install of windows, and the crashes persist. I've removed Ram sticks, and crashes persist after trying out varies combinations of my 4 sticks. I've removed my GPU, and crashes persist, albeit slightly different due to there being a visual aspect to these crashes.

This is what happens during a crash: My pc will hard lock. Any images displayed on my monitor will be frozen, and my peripherals (such as mouse and keyboard) no longer have input, and/or have no power, and such aren't on. (LED light on mouse, and my Audio interface indicates this.)

The crashes have changed before having visual artifacts, which caused me to remove my GPU to verify that's not/or is the cause. After the removal of the GPU my pc would still crash with a visual artififact. After reseating my cpu, ram, removing and installing all my cables again I would no longer get these visual artifacts. Just the good ole' hardlocks.

I'm on my last knee here with my new motherboard installed, and not even 6 hours in, and I crash. I need advice on what to do, what the cause could be, etc. Thank you.

Use Reliability History to look for error codes and warnings just before or at the time of system crashes.

Event Viewer will provide similar information.

Try opening Task Manager or Resource Monitor before you game. What what your system is doing.

Slide the window to one side and game as usual. Look for some resource at a high %. Determine what other applications are using that resource.

Run additional diagnostics via the Windows troubleshooters.

Key is to identify some related error codes or even an event pattern that leads to the crashes.

Taking your advice I went through the Reliability History as well as Event Viewer. I've checked out event viewer in the past, and the only error that related to the times of the crashes would be Kernel Power, which just indicates that my pc was forced shutoff. (which I need to do to reboot my pc when it crashes.)

Reliability History showed me something new though. An error with IAStorDataSvs would occur right at the minute of the crash. My pc crashed 3 times today, twice back to back while playing a game, each it seems with each crash there was an issue with the IAStorDataSvc. So after researching I came across this article (https://www.tenforums.com/general-support/57970-iastordatamgrsvc-stopped-working.html)
, and followed the advice of running sfc /scan now, as well as reinstalling my Intel Rapid Storage Tech. Manager. So I'll keep updating as it goes.

I highly doubt it's a software issue, due to the crashes persisting on the old motherboard when I did a fresh install of windows, but we'll see. It never hurts to try.

Edit: It was not the cause, pc crashed again. I removed sticks of ram to verify it is/isn't the ram causing issues.
