Why does my PC Crash? Reason 1 of 7

by cbschulstad

Hardware Conflicts

Many blue screens are a result of hardware and installation conflicts. All of your system’s components consume IRQs (interrupt request channels) when installed, and every device requires its own channel to function properly. When two devices share the same channel and are used simultaneously, a crash can occur.

Thumb through your Device Manager, and look for any devices marked with a yellow exclamation point. These are the ones with issues, and can usually be fixed with a driver update. Just search your device manufacturer’s website for the latest driver software, or, in a pinch, reinstall the offending hardware itself.

The Device Manager will show you devices with conflicts with a yellow exclamation point.
