Windows 10: PC restarts randomly without warning.

I've been experiencing random PC shutdowns for the past year. These shutdowns occur regardless of what I'm doing, whether it's running demanding programs or simply browsing the web.The frequency has increased recently, happening at least once a week compared to once a month previously. I typically run my PC for 10-12 hours daily, with most of that time being idle.I've already run a memory test with MemTest86 and it didn't find any issues. I've also attempted various software troubleshooting steps short of a complete OS reinstall.Since the cause could potentially be hardware-related power cord

PC Randomly Restarting after installing new Ram!

Tried your suggestions, but still had a restart! Also ran memtest overnight (13 hours according to memtest) and had no errors! Also ran Passmark Burn in test for a couple hours testing everything and had no errors or restart. Could fitting the new ram have triggered something to go bad like my mobo or psu?

Hi,

There may be several reasons why your laptop reboots by itself randomly. We suggest you to run the Hardware troubleshooter and System File Checker tool to scan for any corruptions that may be causing your system to reboot. Kindly follow the steps to run the
Hardware and Devices troubleshooter:

• Type Troubleshooting in the Search bar and press Enter.
• Click on View All on the left panel.
• This will display the list of troubleshooters which are built-in in the computer. Click on
  Hardware and Devices from the list and you can run the troubleshooter.

To run the System File Checker tool, kindly refer to this article:
Use the System File Checker tool to repair missing or corrupted system files.
