Random full system crashes

Thats awful ThatKidOverTher3​ 

Im no expert and a bit difficult to help with so little detail. But i have had numerous issues sorting out both my own laptop and my sons aging pc, to get Apex to run nicely.

The stuttering sound sounds like a hard drive having a fit. Do you have a hd or an ssd? How old is it?

If its a hd, then a culprit might be it needs a full defrag, or is just too full. I find when a hd goes over 50% there can be issues. I'd also run scandisk looking for and fixing errors on the drive.

Defraggler is free and a imo very good defragger. Do not use it on an ssd.

I do a full defrag about every 4 months, otherwise a file defrag monthly.

I use Speccy to keep an eye on the gpu heat during the game. Also free.

I put an extra silent exhaust fan on my sons pc, as well as redoing the cpu paste. That got 10 degrees off the heat.

A windows update set the hd to sleep after 20 min. Might be worth checking that is set to never.

I clean his pc internally, gently with a hoover and small brush, putting in a bit of plastic to stop the fans spinning while cleaning. 

I put all the graphics load onto the nvidia.

Is there plenty of air around the pc?

I use taskmanager to stop unnecessary running background services. I also deleted unnecessary ones.

My laptop uses an SSD so I won’t run the thing you said to not run on an ssd.

 There is plenty of air space as the entire laptop sits at about a 30 degree angle with a wire frame holding it up.

I also use Razer’s software to keep my cou and you usage and temp on my screen at all times while I’m playing.

The stuttering noise has me worried. That really sounds like a hardware problem like overheating. The only thing on my laptop that makes noise is the fans.

Is the noise from internal audio speaker or external, like from the fans?
