Stop codes are not random punishment - each one describes a specific kind of failure. These six cover the large majority of blue screens home and office PCs ever see. Here is each one in plain words, with the first thing to check for each.
A stop code tells you what kind of thing went wrong, not which part is guilty. MEMORY_MANAGEMENT means memory handling failed - but the reason could be bad RAM, a bad driver writing where it should not, or an unstable overclock. So use this page the right way: find your code, understand its family, then confirm with your minidump pattern before replacing or reinstalling anything. One honest rule applies to all six: a single occurrence proves nothing; repetition is the signal.
Plain meaning: Windows caught its memory manager in an impossible state - something corrupted how memory is tracked. The usual suspects, in order: a faulty RAM stick, an unstable XMP/overclock, or a driver that wrote into memory it did not own. Check first: if this code repeats, especially with other changing codes, run a full memory test (MemTest86, several passes) and test with XMP off. Do not reinstall Windows for this code until RAM has been tested.
Plain meaning: a driver tried to touch memory at a moment when that kind of access is forbidden - classic buggy-driver behaviour. This is the most driver-flavoured of all codes. Check first: whatever driver changed last - graphics, Wi-Fi, antivirus, or a USB device driver. The dump file usually names it directly. Roll back or clean-reinstall that one driver before touching anything else.
SYSTEM_SERVICE_EXCEPTION plain meaning: a Windows system service crashed while doing routine work - often a graphics driver, antivirus filter, or damaged system files. If the blue screen names a file like win32kfull.sys, think display path; run sfc /scannow after checking drivers. PAGE_FAULT plain meaning: Windows tried to read memory that was not there. With a driver named in the dump, fix the driver; with no driver named and repetitions, treat it like MEMORY_MANAGEMENT and test RAM - both codes frequently share the RAM root cause.
Plain meaning: a process Windows cannot live without (like the logon or session manager) ended unexpectedly. Because the process itself is part of Windows, the cause is usually underneath it: corrupted system files, a failing SSD/HDD, or malware damage. Check first: drive health (SMART status), then run sfc /scannow and DISM /Online /Cleanup-Image /RestoreHealth. If this code appears during boot repeatedly, suspect the drive before software.
Plain meaning: the hardware itself reported an error it could not correct - WHEA is the Windows Hardware Error Architecture. This is the most hardware-honest code: CPU, RAM, motherboard, power delivery, or heat. Check first: remove every overclock including XMP, check temperatures under load, test RAM, and check the PSU if the PC also restarts under load. Software reinstalls almost never fix a true WHEA pattern. Be honest with yourself here - this code family is where replacement parts eventually come from.
The full blue screen identification method - dump files, stop codes and the fix - shown live, step-by-step.

Yes - malware that installs a driver or damages system files can trigger SYSTEM_SERVICE_EXCEPTION or CRITICAL_PROCESS_DIED. If crashes started after suspicious downloads, run a full scan with Windows Security and its offline scan option after you have handled the driver checks.
That is how most PCs get worse. The same code has many causes, and generic fix lists install driver updaters and registry cleaners that add new problems. Read your own dump file first - it describes your crash, not someone else's.
