Hi everyone. Just got a BSOD while gaming. Please help me find what caused the error and what could i do to fix it. Here's the bugcheck:

WHEA errors never tell me anything, but we can see if the next one - if you get another - shows us.

Can you follow option one on the following link - here - and then do this step below: Small memory dumps - Have Windows Create a Small Memory Dump (Minidump) on BSOD - that creates a file in c windows/minidump after the next BSOD

Open Windows File Explorer
Navigate to C:\Windows\Minidump
Copy the mini-dump files out onto your Desktop
Do not use Winzip, use the built in facility in Windows
Select those files on your Desktop, right click them and choose 'Send to' - Compressed (zipped) folder
Upload the zip file to the Cloud (OneDrive, DropBox . . . etc.)
Then post a link here to the zip file, so we can take a look for you . . .

What are specs of the PC?

thanks for replying. it's a lenovo legion y7000 laptop (i5 9300h, gtx 1650 4gb ddr5). i tried to do a bit of research on my own after the bsod happened, and from what i understood, it's probably a hardware issue. it also might've been caused by the fact that i've been undervolting the laptop (- 0.140 with turbo boost disabled) to lower the temperatures while gaming. however, it would be weirdif that was the case since i've been using the exact undervolting configuration for almost a year and never had a single bsod happening.

Hi, I ran the dump file through the debugger and got the following information: https://jsfiddle.net/x0fnmow3/show This link is for anyone wanting to help. You do not have to view it. It is safe to "run the fiddle" as the page asks.

File information:031221-9906-01.dmp (Mar 12 2021 - 16:05:48)
Bugcheck:WHEA_UNCORRECTABLE_ERROR (124)
Probably caused by:memory_corruption (Process: FIFA21.exe)
Uptime:1 Day(s), 10 Hour(s), 22 Min(s), and 07 Sec(s)

BIOS info was not included in the dump file. This can sometimes mean an outdated BIOS is being used.

This information can be used by others to help you. Someone else will post with more information. Please wait for additional answers. Good luck.

not sure about the undervolted, i will get back to you on that.
Answer
Absolutely, because the memory controller is IN the CPU. Reductions to various CPU related voltages can have a direct, or an indirect, effect on memory performance. That's why changes to things like VCCSA and VCCIO, which are not specifically "dram voltage" can help to stabilize an unstable memory configuration.

Even changes to core voltage might have an effect. We know for sure that historically we've seen many years worth of configurations where running memory speeds above a certain frequency required a CPU overclock (And it's accompanying increase in core voltage) in order to be stable or even POST in some cases, especially when very high speed memory OR four DIMMs were in use.

none of the drivers are the kind that would obviously cause WHEA errors, no overclocking software, lingers on throttlestop …

i ran the intel diagnostic tool and it appears that there are no problems. i also did a prime 95 stress test (smallest fft) for an hour (i wanted to run it longer but my cpu stayed constantly in low 90 C and i did not feel comfortable letting it like that for a longer period), did not encounter any crashes or bsod.

All we know for sure is its likely hardware

we don't know what yet, we can guess all we like. Need to test things to cross them off list.

CPU - passes 2 CPU tests
Ram - Prime checks ram as well, but I don't know how many tests it run
Try running memtest86 on each of your ram sticks, one stick at a time, up to 4 passes. Only error count you want is 0, any higher could be cause of the BSOD. Remove/replace ram sticks with errors.
Memtest is created as a bootable USB so that you don’t need windows to run it

GPU - just run benchmarks, I don't need results, just seeing if it crashes. Don't run both at once
https://geeks3d.com/furmark/

https://benchmark.unigine.com/heaven

what else is in there? what storage drives?
I don't see many laptops so can't really test PSU or MB.

checked ram with windows memory diagnostic and memtest86 : everything seemed fine

checked gpu with furmark and unigine heaven : not a single problem

checked storage (i have a 512 gb ssd) with hdd sentinel - health was at 100%

so yea, everything seems fine.

i got the bios update three or four days ago through the lenovo vantage utility. same thing with drivers, everything is up to date

so yea, no idea what to do next. i did not get another bsod, so the dump i posted here is the only one i got. i guess the most probable culprit would be the undervolt (already disabled throttlestop).

nothing. only got one bsod, no random restarts or any other things to note.

i still have a year warranty left, so if anything bad happens, i know what to do. it's just frustrating that i can't pinpoint what's wrong.

wait and see. Just use PC as normal and assume its not going to happen... saying this may jinx you but it would happen anyway.

it might have been fixed by bios update. its not like you haven't tried.

Its impossible to tell if BSOD are fixed until they stop, that is only real way to know unless driver waves a flag and shows its name and we replace/remove it.

its too soon.
