Similar to a computer that won’t turn on or a blank screen that stubbornly refuses to boot, a computer that stalls out during start-up can be one of the most panic-inducing moments for any computer user, but it’s often an easy fix. Sometimes your computer begins to start up, but after a moment just randomly stops responding and gets frozen during the startup process. This problem can be caused by many factors, but you can run a few simple at-home diagnostics to determine the root cause.
Your PC might be trying to load or override windows from removable media. Check and remove any CDs, DVDs, USB flash drives, or memory cards from your computer’s disc drives. Remove any digital cameras or external hard drives. Once all drives have been checked and emptied, try restarting your machine. If it fails again, it’s safe to assume something else is causing the problem.
If your desktop displays an error message during startup, this is probably caused by a hardware configuration problem. Your motherboard, CPU, memory or graphics card may be corrupted.
