So I've started having incidents were my PC crashes 2 or 3 in a row every few months. It most recently crashed yesterday while gaming, voice chatting in discord, and listening to some music. The crash had a BSOD, but I don't have the error code from the BSOD unfortunately. Not all of the crashes are BSOD. I'm pretty sure it's my CPU since in Windows event viewer it states it was a fatal hardware error reported by the processor core. I became fed up and went out a bought a new AMD 5800x3d. Even though I'm currently using an AMD R7-5800x, I thought I might need to update my BIOS, so I updated to the latest BIOS. I noticed in the release notes of an newer version that the update increases stability of AMD 5000 series CPUs. So I decided I wanted to try to reproduce a PC crash before swapping out my CPUs. First, I started by running Cinebench R23. After like 30 minutes of Cinebench and no crashes, I decided to run FurMark and Cinebench at the same time to see if maybe it was a PSU issue. After like tens minutes of both, no crashes. I really wish that I tried to reproduce the issue more consistently before upgrading my BIOS. I'm curious what are other people's opinion on what the issue is. Did updating my BIOS fix my crashes? Is there some other testing I'm unaware of that I should try? Should I test longer? As for my new CPU, I am tempted to return it if I'm not crashing anymore. But I definitely want to swap it out if I can prove my old CPU is causing my crashes. Here's a link to a bunch of screenshots that contains my system info and the errors from Windows event viewer. If it's better to post the individual images on here, I can. https://imgur.com/a/rPG8Inh Here's my PC build on PC Part Picker: https://pcpartpicker.com/user/dinotroope...iew=RLCf99 I tried to get a dmp file from the BSOD, but there weren't any from yesterday. I also tried to get a perfmon report, but it never completed after 60 seconds.
your b450 motherboard often needs a BIOS update to support Ryzen 5000 series CPUs, which greatly increases your chances of resolving the problem—though it's still uncertain. If you have funds, the X3D version is worth considering because it usually brings better gaming performance. Also, Windows Home users should definitely upgrade to Pro for more features.
It's a real lucky situation since updating the BIOS is essential to run a 5000 CPU on an older motherboard. Most systems won't even start without the fix. Still, I’d suggest getting the X3D chip if possible—it really performs well. For Windows Home, it makes sense that people appreciate free resources.
