Black screen when you turn on your PC? Walk through the diagnosis from display cables to boot failures.
Most people search for help with this when something stops working or starts acting up. Computer Shows Black Screen on Startup — Fix Guide is one of the most common issues we see, and the fix is usually simpler than you'd expect.
Start with the simplest possible solution and work up. Most of the time, the first or second step solves it.
Step 1: Restart the device. Yes, really. A clean restart fixes more problems than any other single action.
Step 2: Check for updates. Operating system, drivers, and app updates often include fixes for exactly the issue you're seeing.
Step 3: Look for recent changes. Did you install something new? Change a setting? Connect new hardware? Undo the last change and test again.
If the basic steps don't solve it, or if you're not comfortable digging deeper, that's exactly what we're here for. There's no shame in calling a pro — it's usually faster and cheaper than trial-and-error.
Some signs you need professional help: the problem keeps coming back after you fix it, you see error messages you don't understand, or the device is physically damaged.
