explorer.exe and sihost.exe crashes at startup (happens randomly)


Ever since the brownout occured in the afternoon, now I get the explorer.exe and sihost.exe crashes at startup, plus it happens randomly.

First step I did was using the sfc /scannow and it didn't find anything wrong. Does anyone have the same problem or is it something that is ciritically wrong such as hardware. Thanks!

 

Laptop randomly crashing often but resolves itself

My Acer Nitro 5 (purchased in 2019) often crashes randomly, especially during gaming. Sometimes, my screen just freezes and I am forced to shut down the laptop. When I boot up the device immediately after a crash, I get the following "No Bootable Device" screen






In other times, my laptop shows the following error before crashing:





After getting this error, the laptop boots up and shows the "no bootable device" screen again.

When I get the "No Bootable Device" screen, I just wait for a while (around 15 minutes) and when I boot up my laptop it works normally, but the laptop working occurs randomly. My laptop is working now but is unreliable.

I checked the BIOS when the laptop works normally and it appears my HDD gets detected (check HDD1 Model Name below)





And when I check the BIOS when I get the "No Bootable Device" screen, my HDD does not get detected (notice that in the image below, the BIOS does not recognize the drive in the HDD1 slot)






I just did a fresh install of Windows 10 around a month ago and all my drivers are updated. Is there anything I can do to reduce the number of times my laptop crashes? It has consistently been crashing at least once every two days.

 

My laptop has been crashing randomly

My laptop has been crashing randomly. (youtube, games, just turning it on)

There has been 2 stop codes that I see; ''Thread stuck in device driver'' and ''DPC Watchdog Violation''

I just bought this laptop and the only thing I've done is installed an extra 8GB of RAM.

I've read a few similar problems and I have updated drivers and I have ran the memory test but it still randomly crashes.

I really need help and I'm willing to go through it step-by-step.

Thank You!

Attached is the error report:
