    Quick, right now, think of any changes you may have made to your computer recently. Have you installed any new hardware? A new driver? Connected a new component to your computer? Have you opened your computer’s case?

    It is very possible that you are dealing with incompatible hardware, a new hardware driver may be glitchy, or you may have unplugged something while inside your computer tinkering with its guts. Do any of these apply to you?

    The computer won’t power on at all – Make sure you are plugged into an outlet and that the power connector is good and tight. If you are dealing with a desktop, make sure the power switch on the back of the case is powered on. If it still won’t turn on, the power cable inside the case could be disconnected. If you haven’t touched the inside of your computer, your power supply is most likely dead. You have two choices: get a new power supply or just replace the entire thing. The power supply is going to be your more affordable choice.

    The computer comes on, but it says “No bootable device.” – The computer just can’t seem to boot from the hard drive that contains Windows. You will need to enter the computers UEFI firmware setup screen or BIOS and check the boot order setting. This will make sure Windows is set to boot from its hard drive. It may just be a little confused.

    If your hard drive doesn’t appear on the list, it is probably a bad hard drive and that is why it can’t be located. If it is dead, it can’t be booted from. You can insert your Windows installation disc or recovery discs and run the “Startup Repair operation.” This is done in an attempt to make Windows bootable again. If this doesn’t work, you definitely have a hardware issue.

    Windows freezes or crashes during boot – If Windows starts to boots and then fails part of the way through, you may be facing a hardware or software issue. You can perform the Startup Repair Operation using your recovery or Windows disc if it is a software issue. If the computer throws errors while attempting the reinstall or startup repair or the reinstall process works okay and you still encounter the same errors, you are most likely dealing with a hardware issue.

    Windows starts and then freezes or the blue screen of death appears – If the blue screen of death shows up or Windows freezes after start, you may have a bad driver or malware that is running at startup. You can boot your computer in Safe Mode because the typical drivers won’t load at startup. This can help you isolate an issue. You can do a system restore and scan for malware. This will solve the issue if it is a software problem. If your problem still isn’t fixed, then you may want to reinstall windows. If you have Windows 8, you will want to do a reset or refresh. This will revert your computer back to the factory settings. If you still have crashes, then you know you have a hardware problem.

    If you have Windows 10 you will have a couple of options. Reset your PC and KEEP YOUR PERSONAL FILES, which is the best choice for most people. Option 2 - Reformat the drive and TOTALLY WIPE IT OFF. Unless you have a bad virus this option is normally not necessary. Always back your files up, and never do any of this tasks unless you have experience and feel comfortable doing it.
