You may even see instructions on the screen at startup that tell you which key to press. Once you're in the BIOS or UEFI, make sure the computer is set up to boot to your primary hard drive , disable Fast Boot, and look for any other unusual settings that might be causing startup problems.

If you can get to your computer's BIOS, you might also be able to get to Windows' special boot options. If possible, start the computer in Safe Mode. It can be tricky, so here's how to do it. If there are any power lights or signs of activity, hold the power button for 10 seconds to turn it off.

That generally means removing the printer cable, scanner, webcam, and anything else connected to the computer. Now, try booting the computer with just the power cord, monitor, mouse, and keyboard.

For the most part, that means inspecting the video card, sound card if you have one, memory chips, and all the power and data cables. If your computer is clearly powering on but won't boot properly to Windows, your computer may be infected with malware , such as a virus or ransomware.

Poorly written malware can be buggy enough that it prevents Windows from running correctly. You can try accessing your anti-malware software from a USB. Try to boot your computer not from the internal hard drive but a USB drive. Microsoft does not guarantee the accuracy of this third-party contact information.
