Question PC bluescreening occurs unexpectedly.
Question PC bluescreening occurs unexpectedly.
Since February I've been facing unexpected BSODs while gaming. Recently it occurred while I was just watching some Twitch streams and I'm really concerned. According to BlueScreenView, ntoskrnl.exe, dxgkrnl.sys and nvlddmkm.sys were the culprits, but I haven't found any solution to fix it. I've attempted sfc /scannow and it seems to repair corrupted files, yet the BSOD keeps happening and I have to restart everything again.
I believe you encountered some malicious software.
You may want to perform a malwarebytes scan, focusing on files starting with NEP in the name.
Open Windows, disable virtual memory to clear pagefile.sys, then restart Windows, enable virtual memory, launch cmd.exe as administrator, and execute dism.exe with the specified options.
After that, remove any unused software and update the remaining ones.
Then carry out a malware scan if desired.
It’s unclear exactly what is behind the issue—possibly a bug in an outdated driver. You might need to activate verifier.exe testing to accelerate the bugcheck process.
You can simply reformat your system and update the BIOS to resolve this issue. It might be helpful to follow a clear guide, as it can simplify the process and reduce confusion about which drivers to install or remove. Malwarebytes didn’t detect anything, so that didn’t help either.
I discovered a document suggesting the NEPxxxx file is a Chinese game developers anticheat driver (NetEase Protect). The name begins with NEP followed by random characters to confuse cheating software. Renaming the file makes it difficult to block its execution. Clearing Windows is time-consuming. You’d need to update the BIOS, format and reinstall Windows, apply updates, and install motherboard drivers without updating utilities. After that, install all your software. It seems the system often crashes, so a daily reboot—shutting down and restarting—might help. If I were you, I’d update the BIOS, CPU chipset drivers, and possibly some motherboard drivers. Then run autoruns64.exe to remove outdated drivers and check if the issue resolves.
