Windows 11 BSOD appears due to hardware or software issues.
Hey everyone, I'm getting really confused about this issue. EDIT - I'm trying to show off the weird stuff at the bottom, but only the worst parts are showing. Error code 0xc000021a. EDIT - I managed to fix it with a benchmark test, but it keeps happening. First noticed in F1 2021; my whole system would freeze and then crash. After reseating RAM, it worked for a while, but then it came back. Also experienced this on DOTA 2 after finishing a session. Interestingly, at lower resolutions like 720p or 1080p I can play longer, but jumping to 1440p causes an instant crash. So far I've done: reseated RAM, changed GPU slots, updated CPU drivers, used DDU to clean up drivers, and installed a fresh Windows 11 copy. This BSOD seems odd—what's going on at the bottom of the screen? Feels like something's glitching. Thanks, George.
Noted the discussion you shared. It seems the problem might be tied to your graphics card. If that’s the case, spending on an Alder Lake or similar upgrade wouldn’t be worthwhile. At lower resolutions like 720p or 1080p, the CPU handles more work. Higher resolutions shift the load to the GPU. Could you borrow a friend’s GPU or use an older one for testing? Please share your full system details.
Hmm, are you referring to ReBAR or something similar? Was the AMD model called SAM! Smart Access Memory? It's a BIOS configuration. Upon rechecking your troubleshooting steps, it seems you didn't adjust anything in the BIOS. Consider performing a CMOS reset.
Interestingly, does the RAM come with a JEDEC profile at 3200? On enthusiast boards I usually see a lower JEDEC profile combined with a quicker XMP version at the rated speed. If it's using a different profile, that might rule out the RAM. Have you performed any RAM testing, such as MemTest or similar? Just to confirm there aren't issues.
I tried to skip the RAM and took another shot with this setup. It didn’t work well overall. The biggest improvement came from adding a small positive voltage boost to the CPU—around +50mV was the smallest adjustment I could make. This helped cut down crashes, though it didn’t fully stop them. Based on what I remember, the motherboard likely had faulty VRMs (ITX form factor) and wasn’t compatible with newer Ryzen chips compared to older models. That explanation doesn’t seem very likely, but if you have no other options, it might be worth a try.
