Detailed explanation-1: -A user reports that their computer’s screen is blank after they power it on. The user hears the power supply fan running and there seems to be no power issues with the computer. What do you tell the user? The computer has incompatible memory modules or memory modules aren’t installed correctly.
Detailed explanation-2: -Step 1: Check Your Cables Make sure any surge protector or power strip is correctly plugged into the outlet, and that the power switch is on. Plug in other devices to the power strip and confirm they are operating properly. Double-check that your PC’s power supply on/off switch is on.
Detailed explanation-3: -You’ve no doubt become accustomed to hearing the little fan whirring inside your computer to keep the components cool. If that occasional whirr has changed to a constant drone, and your computer suddenly refuses to power up, you’ve got a problem. It could simply be overheating, or a failed component.
Detailed explanation-4: -If your computer won’t boot up, the first thing to do is make sure your PC is plugged in and the power switch is turned on. If it is and it still won’t start, try plugging your computer into a different outlet. If you’re using a power strip or surge protector, plug it directly into the wall instead.
