Play CheckIt 3.0 - PC Diagnose Programm Online
You click through pixel-perfect DOS menus running fake diagnostics, where the real challenge is not accidentally crashing your virtual PC while pretending to know what you're doing.
Game Overview
Ever dug through old DOS floppies and found something unexpectedly charming? CheckIt 3.0 looks like just another diagnostic tool at first glance—until you realize it’s basically a retro tech support simulator wrapped in glorious 16-bit aesthetics. You’ll poke at virtual motherboards, run memory tests that take suspiciously long, and try not to "fix" things so hard the whole system crashes (which, honestly, happens more than you’d think).
There’s no explosions or power-ups here—just the weirdly satisfying thrill of troubleshooting a fake PC with all the clunky menus and cryptic error messages of the early '90s. Half the fun is figuring out what half these options even do, like some archeologist deciphering ancient tech. If you’ve ever nostalgia-tripped over the sound of a floppy drive seeking, this’ll hit that sweet spot between "oh wow, we used to do this?" and "wait, why am I enjoying this?"
Fair warning: after an hour of pretending to be a vintage IT wizard, you might catch yourself eyeing old beige keyboards on eBay.
Each game uses different controls, most DOS games use the keyboard arrows. Some will use the mouse , "Alt" ,"Enter" and "Space bar".
