My game keeps crashing or blue-screening, is my PC dying?
Nah, your PC probably isn’t completely dying just yet, but a game pushing it to its limits is definitely forcing a hidden problem to surface. When you’re gaming, your parts are working their hardest, which means a weak power supply, a bad driver, or trapped heat will trigger a blue screen instead of just quietly running in the background.
Quick things to check first
- Check your temperatures. If your case feels like a space heater, pop the side panel off and see if it’s just choked up with dust. Give the fans a good cleaning with some compressed air so the heat can actually escape.
- Make sure you aren’t asking the computer to do more than it can handle. If you bought a budget or older rig second-hand, trying to crank all the graphics settings to Ultra on a brand-new, demanding game will just overwhelm it and force a crash.
- Update your graphics card drivers. A lot of times, a new game and an old driver just don’t get along, and updating that single piece of software can magically fix the crashing.
- Turn off any automatic overclocking. If your buddy had the PC set to run extra fast to squeeze out more performance, that’s a classic way to crash a system when it gets stressed. Set everything back to default in your software.
If that didn’t fix it
- Run Windows Memory Diagnostic. Hit your Start button, type “Windows Memory Diagnostic”, and run the tool. It’ll restart your PC and check your RAM for physical defects. If it finds errors, you likely have a bad stick of memory that craps out when the game tries to load big textures.
- Test your power supply under load. Sometimes a power supply is dying and can’t provide enough juice when your graphics card asks for it. You can use a free tool like OCCT to stress test your system—watch the voltages in the monitoring section. If the 12V rail dips way down when the test starts, your power supply is struggling.
- Check the Event Viewer for the exact error code. Right-click your Start button, open Event Viewer, and look under “Windows Logs” then “System” right around the time the crash happened. Look for a “BugCheck” or “Critical” error. Write down the error code it gives you, because that tells us exactly which piece of hardware is throwing the tantrum.
- Roll back your GPU driver using DDU. WARNING: Using Display Driver Uninstaller (DDU) is a bit risky and requires booting into Windows Safe Mode. If you do this wrong, it can mess up your display and leave you troubleshooting in a blind panic. Only use DDU if you suspect a deeply corrupted driver, and follow their instructions to the letter to completely wipe the old drivers before installing fresh ones.
When to call a pro
If your PC gets to the point where it won’t even boot into Windows anymore—like if it just gives you a black screen when you turn it on, or it blue screens before you can even open a browser—stop messing with it. Also, if you run a memory or CPU stress test and the computer immediately shuts down or smells like burning electronics, you’ve got a serious physical hardware failure that needs a pro’s hands.
Pro tip
When you buy a used PC, always wipe the storage and do a fresh install of Windows so you aren’t dealing with the previous owner’s weird settings and leftover junk. Keep an eye on your fans for dust buildup every couple of months, because heat is the absolute enemy of computer parts. Finally, never cheap out on the power supply when it’s time to upgrade, since a bad one will literally fry the rest of your expensive hardware.
