A Blue Screen of Death ("BSoD" for short), officially known as a Stop Error, is a feature of the Microsoft Windows operating system, being present from Windows NT 3.1 (with precursors as far back as the beta version of Windows 1.0).all the way to Windows 10 and early versions of Windows 11. (In fact, Windows 11 initially changed it to black, but a later update changed it back to the traditional blue, before it was finally changed to black with text in the middle, parodying the old school Game Over screens, in 2025.) When the system crashes, it puts up a plain blue (or now black) screen with some text on it which might help the user diagnose the problem, or at least give them something to quote on the phone to tech support. The Other Wiki has full details.
Windows 10 added a QR code to the screen, which took the user to a page on the Microsoft Support website about their specific problem so they could quickly research the issue, if they scan it while the screen is still up.
The term has thus become a Fan Nickname for stop errors generally. Stop errors are only supposed to appear very rarely, but in older versions of Windowsnote they were common enough that most regular users came to know of the Blue Screen’s existence. Microsoft themselves have used this term on and off. Its most spectacular appearances have been at demonstrations of Windows-based systems (including one where Bill Gates himself witnessed it), or worse, on large-scale public display systems that were running on Windows machines (including at the Beijing Olympics in 2008); collections of images of such events can be found online. Nonetheless, the most infamous (and horrifying) appearance of the Blue Screen was on July 19, 2024, when an erroneous update to CrowdStrike's widely used security software caused roughly 8.5 million Windows computers, mostly on corporate systems, to crash, leading to blue screens all around the world, including in locations such as airport baggage reclaim systems.

The Blue Screen of Death has never really become a trope in its own right, but it has at times become painfully familiar enough to Windows users that, given the OS's ubiquity, most people who used computers would understand an allusion to it. It is a useful metaphor for a traumatic emotional crisis of some kind, when a person freezes up and becomes incapable of action; it is referenced by the trope names BSoD Song, Heroic BSoD, and Villainous BSoD. However, later versions of Windows handle software crashes and radical glitches a little more gracefully, so the Blue (or Black) Screen is less often seen these days (it usually indicates a faulty device driver or a hardware failure when it does occur), and those references will likely become increasingly obscure to new readers in coming years.
Aside from Windows, lots of other operating systems and electronics have specific ways of conveying a fatal system error; for example, on Unix and Unix-like systems, they're called kernel panics, while old Amiga systems had Guru Meditations. In any case, perhaps due to the prevalence of the BSoD name, if a computer or system has a fatal system error state, it's usually known as a "[something something] of Death". (For example, see the "Red Ring of Death", as seen in the tropes Heroic RRoD and Villainous RRoD. Named after a warning message on the Xbox 360, it's the physical equivalent of the BSOD's mental/emotional overload.)
Incidentally, if you want to blue screen or cause a Non-Standard Game Over to your computer intentionally, there is an official — but unsurprisingly obscure — method of doing so. It involves editing the Windows registry to enable a "CrashOnCtrlScroll" function, then holding right Ctrl and pressing the Scroll Lock key twice.note

Depictions of the Blue Screen of Death in fiction:
- A Protegent Antivirus ad has a "Proto's Identical Stranger" using a computer, then a image of a BSoD appears, albeit with a video editing transition effect instead of the screen suddenly going black. Also, there's a yellow "WARNING" text over the BSoD image.
Not Proto: Whoops, my system crashed, I lost my data, but I had an antivirus.
- CMC+: Windows 10's Final Smash is the BSoD; it's at first heralded by multiple (joke) error pop-ups to trap any nearby foe, then the music suddenly stops as the blue screen flashes to obscure the battlefield and the fighters, staying on said screen for a while until the caught enemies are suddenly damaged and launched away as the blue screen vanishes.
- In The Drama, Emma's attempt to film a school shooter manifesto video is cut short when her computer crashes with a BSoD.
- In Andy's Apple Farm, if you repeatedly select the file "ANDY 2", it will cause the Blue Screen of Death to appear, but there seems to be a face hidden in the BSoD that can be seen by increasing the contrast, making it fake all along.
- In Beatblock, the Computer Virus themed level ILOVEYOU.vbs has a Blue Screen of Death appear alongside several other glitches and pop-up windows. Scanning its QR code opens a website with several fake download buttons for "Free Beatblock"
- Blade Strangers has one disturbing possible ending in which a (dummy) BSoD features.
- Destroy All Humans! Big Willy Unleashed: Crypto finding Pox's junked projector results in the blue screen upon reactivating, with Crypto naming it as the BSoD upon seeing it and when trying to get tech support to revive Pox.
- Epic Battle Fantasy 5 briefly gives a fake Blue Screen error upon killing the optional Glitch boss
- A Sanity Meter effect in Eternal Darkness Sanitys Requiem is to toss up a BSoD. The game is exclusive to the Nintendo GameCube, by the way.
- In Warhammer 40000 Fire Warrior, the Emperor class battleship's guns' machine-spirit is revealed to be the Windows 95 operating system, as every screen you find on the ship's gundeck is displaying its Stop Error message.
- Foxo's Fun Schoolhouse displays a Windows 9x-era BSoD if you try to name yourself "aux", "nul", "con", "com", "prn" or "lpt" (which cannot be used as filenames in Windows) in the name select screen.
- Goat Simulator 3 has the goat destroying the game's in-game servers, causing the corruption of the entire game. As a result, the game and the computer crash and display a Blue Screen parodying the one in Windows XP. Thankfully, the computer's operating system reboots itself while jokingly talking about its life, and everything is still intact, albeit the game is more broken, glitchy and buggy than ever.
- Henry Stickmin series: One is displayed in Stealing the Diamond when you choose the Pokéball/Goodball to distract the guards, which unleashes Missingno and "crashes" the game. The original Newgrounds version even uses the actual Windows 9x-era BSoD for the crash screen.
- maimai uses the BSoD for horror during the KALEIDXSCOPE boss song event: One of the Phases involves a boss song with its information glitched out. If you make it to what appears to be the end of this song, the game appears to crash and an XP-style error screen appears, explaining that "A problem has been detect (sic) and 7sRef.exe has been shut down to prevent damage to your world", and goes on that if problems persist, the entire world of 7sRef will be destroyed. The player has to follow an Alternate Reality Game to unlock the remaining phases and the clear the Final Boss song of the event to save the worlds of the maimai universe. An 8-style BSoD parody appears in the Post-Final Boss track "Ref:rain (for 7th Heaven)", but this time with a positive spin: "We ran into a problem, then you saved us. Thank you."
- Being software developed by Microsoft themselves, Microsoft Flight Simulator uses a version of this as their Game Over screen to inform the player about aircraft overstressing, collision, or wrong meager in handling their aircraft. Depending on the version, it could be either a pop-up type or a full-screen variant.
- Portal 2: In the final third of the game, the Enrichment Center's nuclear reactor is inching towards meltdown. A couple places show a Blue Screen informing of the reactor's situation and what steps can be taken to avert the worst.
- Progressbar 95 uses BSoD parodies as its Game Over screens, with the appearance matching the current in-game OS you're using (those OS's being parodies of various Windows and Mac OS iterations).
- Animator vs. Animation: The ending of Animator vs. Animation III has the Dark Lord and the Chosen One team up to destroy the Animator's PC, sucking everything into a white void that then explodes, causing cracks in the monitor and forcing a Blue Screen that declares the entire computer will be terminated. This was originally supposed to be the end of the series until it was brought back three years later.
- Computer Showdown: Given that the series is centered around various operating systems, the BSoD has made many appearances, alongside a few other screens of death. Most notably, one of Virus Maker's attacks summons various screens of death from Windows against opposing Syms.
- hololive ERROR: At one point in Chapter 9 of the animated web series, a blue screen briefly flashes by. Instead of having the typical blue screen text, it lists off a bunch of hexadecimal color codes that correspond to the color palettes of the Virtual YouTubers who voice acted throughout the series.
- "Hazbin Hotel": In Radio Killed the Video Star, Vox briefly bluescreens during his Quarreling Song with Alastor. The message on his screen says that the application crashed due to Alastor.exe.
