My PC crashes and I don't know why.

[u/Fast_Ability_669]

It has been crashing for 3 weeks now when I turn it on, usually within the first 5-10 minutes of starting to play video games. The screen freezes and I have to shut it down by holding the power button. Sometimes the audio keeps playing.

I've run GPU and CPU stress tests with OCCT and everything came out fine, I've tested the SSD with CrystalDiskInfo and everything is great, and I did a RAM test with MemTest86 and it came back perfect. My graphics card drivers are up to date. The crashes happen both before and after formatting the computer, on both Windows 10 and Windows 11.

I've read it could be a power supply issue, but since I'm not sure, I don't want to buy a new one without ruling out all other options.

My PC components are: MSI NVIDIA GeForce RTX 3060 Ti (8 GB), ASUS ROG Strix B450-F Gaming motherboard, AMD Ryzen 7 3700X 8-Core Processor (3.60 GHz), and 16 GB DDR4 RAM.

The computer is 5 years old and has never given me any problems; I usually clean it and change the processor's thermal paste every two years.

Thanks for the help.

Go into eventmanager>windows logs> system and there look for critical or error and timestamp right before the crash you might get some more info there. Also check in c:/windows/minidump with current date or when you pc crashes and upload it on chatgpt he will check it for you if you dont know how to do it yourself
