Question My PC crashes repeatedly ?

[Reaser714]

My computer was working fine until the last 5 months. At first, the red CPU LED lit up while I was working in Windows. Then I cleaned the PC and the issue went away for a few months. But a few days ago, Windows started crashing, and then the blue screen appeared , followed by the red CPU LED turning on again.
Windows even crashes in Safe Mode.

Now, when I try to turn off the computer using the power button, it doesn't respond at all.

My specs:
Motherboard: MSI B450 Carbon AC
RAM: Corsair Vengeance RGB DDR4 RAM 32 GB 3600 MHz
CPU: Ryzen 5 3600
GPU: Asus ROG Strix GeForce RTX 2060 Super 8G
SSD: Samsung SSD 970 EVO Plus 500 GB (for Windows only)
HDD: WD Blue 1TB
PSU: BitFenix Whisper M 750w
CPU cooler: stock

Take a look in Reliability History/Monitor. Are there any error codes, warnings, or informational events being captured just before or at the time of the crashes?

There are other places to looki but for now simply focus on Reliability History/Monitor and the presented timeline. Look for errors, warnings, informational events and patterns.

Note and post error codes.

Do you normally turn off the computer by right-clicking the Windows icon and then selecting the "Shutdown" menu choice?

For the most part that is how Windows should be shutdown.

However, BSOD's etc. can force end users to do some sort of hard power off.

Which can and does cause file corruption problems.

After the next successfull boot run "dism" and "sfc /scannow" to find and repair file problems.

If that does not work then the next step would be to properly power down (if possible), unplug, and open the case.

Verify that all connections, plugs, jumpers, RAM, and case connectors are fully and firmly in place.

Current objective being to narrow down the potential culprits.
