Windows 10: Computer Won't Boot

Recently upgraded to Windows 10. Everything seemed to go well. It was working fine I restarted a couple times and it all went well . I shut the computer down for about 20 minutes and when I tried to restart it I get nothing on the monitor. I can hear the hard drive start but monitor doesn't come on unless I hit the power button on the monitor and even when I do it just comes on for a few seconds and it is blank and it says monitor is going to sleep and shuts off again and if I hit the power button again it will just repeat the cycle. Any ideas

:)

 

Computer won't boot

Try pressing F11 or startup reboot, then if you have a blue screen wait at least 20 to 40 minutes.

 

Computer won't boot

I tried this but it just rebooted itself again sadly

 

Hello, welcome to tenforums. Sorry to hear of your problem. Can you confirm you see absolutely nothing whatsoever after trying to boot your PC? Normally you might get some sort of manufacturer's logo, options for BIOS (if using BIOS) etc.. i.e. a display which does not originate from Windows.

But you then say it says it's going to sleep.

That suggests you are having a sleep related issue.

There are many many threads on sleep problems on this forum.. have you tried searching for 'sleep' 'won't come out of sleep' etc?
Worth having a good look, and then post back.

 

Sounds to me like the PC is not even booting up. Do you hear any BIOS beep(s) to indicate it has gone through the POST (power-on self-test) stage?

 

mm, that's what I now guess reading it again.. maybe the message on the monitor relates to the monitor alone, not the PC?

Lydnsn- you need to be clear as to whether it's a potential hardware problem - check basics like connections- I suppose you could try putting in a bootable disk (assuming your PC was set up to boot from one) and watching the drive light to see if anything happens- but that's only meaningful if your PC gets past UEFI/BIOS POST.

Please advise.

 

I don't hear anything just hard drive starting. Monitor is good I connected another PC to it and its just fine. It's not booting for sure but I can't get no display to make any changes. BIOS doesn't come up . If it did I could maybe try booting from a disc but at this point I'm stumped

 

Hi, thanks, ok, we'll have to assume it's a hardware issue. In which case you might want to consider whether there's anything on the disk or disks for which you haven't a backup...

We don't know what sort of PC you have lacking your system specs, but if it's a desktop you do have more options.

Good luck..

 

From what you have provided here, it sounds like an issue with your gpu. Can you tell us if you have a dedicated video card installed in your machine?

Also, on the assumption you are using a remote monitor, this is a desktop pc correct? Can you please provide the Make / Model number of the tower.

 

A Windows problem wouldn't prevent the POST (power on self test) from displaying.

That means that you either have a hardware problem, or somehow the BIOS settings have gotten messed up.

If it's the BIOS settings, the check for that would be to clear the settings.

For desktop PCs, there is usually a jumper on the motherboard to do that. Newer motherboards sometimes have push buttons on the motherboard or (better) in the rear IO panel to do the same thing. Yet another way is to remove the coin cell that maintains the CMOS settings.

For a laptop, the only way I've ever cleared the CMOS settings was to disconnect the CMOS battery. Sometimes that is accessible, but not always.

If that doesn't do it, I'd suppose a hardware problem. That's a whole 'nother level of complexity for troubleshooting.

Best of luck.

 

I just wanted to chime in on this old post... I've discovered that I've been experiencing the same issue as everyone else when it came to upgrading to Windows 10 from a previous Windows version. My computer(s) would not boot past the POST manufacturer splash screen. It didn't matter what brand name it was or whether or not it was a laptop or desktop. I've discovered the solution would be to put the Windows 10 media into the DVDROM player and boot off the player. Each manufacturer computer has different Function keys to do this, so just use the one for your brand computer. Once you've booted off the media, if asked if you want to continue with the upgrade or do a fresh install, choose the fresh installation. Then continue on with the installation and when you get to the "upgrade" or "custom" option, choose "custom".
then delete the main partition which the OS would reside on and create a new partition. then just proceed with the installation as usual.

This has only been the solution that has worked for me each and every time with HP, Gateway, Dell and Lenovo systems.
Also the other option to make sure is that in your BIOS, make sure "secure boot" is disabled and that your legacy option is set to UEFI and not AHCI.

Most of these responses are not really relevant to this common situation because most of the time doing an upgrade had nothing to do with bad hardware, it's just a corruption process during the upgrade process with the Windows 10 OS.
So I wouldn't waste my time checking the hardware after an upgrade when your computer was running just fine before the upgrade.

 

Thanks a lot for a detailed explanation.
I've experienced the same problem on my desktop many times when I discovered that putting the PC into Safe Mode and then (without changing anything) rebooting it solved the problem (probably by "resetting" all the half-baked modifications I had made with my computer).
