PC won’t start up, only Safe Mode without networking works, how do I fix it?

My desktop is stuck booting up, just get to the HP logo with the “hour glass”, no further. Tried safe mode but don’t get much out of it, unfortunately safe mode with networking doesn’t work so I can’t try updating any drivers. Did a Windows reinstall but it didn’t help. Also tried a BIOS upgrade but it won’t kick in for some reason, still have the VA0.11 version instead of the latest available, VA0.13. Might be be of interest that the initial problem, that I tried to solve, was that after normal boot up the start screen (the desktop) flickered, 1-2 seconds normal, 1-2 seconds black screen, and it went on and on like that until I restarted. No way to start up any applications. Hence the attempts to start via safe mode. When I did Ctrl-alt-del, the menu and the task manager did, however, not flicker, whatever that means in terms of software failure or hardware failure. Any idea what I have broken and how I best fix it? I guess safe mode with networking is a good start but why won’t that work? I'm using a network cable and nothing wrong with the network. Thankful for any good idea!

    What flavor of Windows 10 are you using now, like Enterprise/Pro/Pro Education? What is the medium that you used to install like CD/ DVD or Flash drive or other way? How did you install the OS, either just reinstall the OS or delete all partitions (before doing that, take all necessary backups, if any) and make again partition like C/ D etc. and then going to install? Why did you reinstall the OS, is the system infected by viruses or other reasons? Have you other version of Windows like 7/8.1?

    I did the reinstall because I ran out of options, at least on my level of skills. The original problem was the flickering desktop screen.

    The OS is Microsoft Windows 10 Home (64-bit) and it was preinstalled on purchase so I don't have a separate medium. I did a Reset this PC (reinstall Windows and keep the files) from the boot up menu / Troubleshoot / Reset this PC / Keep my files. No problems during reinstall that I can remember.

    The BIOS upgrade, I downloaded a newer version on another PC, transferred it to the broken one via USB and Safe mode. Tried to upgrade through Windows but I guess safe mode prevented it, after unzipping and run nothing really happened. I also tried from the boot up menu from a USB stick but didn't get that to work either.

    BIOS upgrade? After the upgrade, did you try booting to BIOS mode and make sure the settings are correct for drove order? Does it boot from CD/DVD 1st, then HDD 2nd. Do the other options look correct for your system specs?

    Focusing on the main problem as you described, "original problem was the flickering desktop screen". When you reinstalled the OS, make sure the all software drivers are installed properly. Not only that, sometimes, it is necessary to configure also. Have you contacted HP?

    Ok, are you suggesting that I go through the drivers in device manager one by one and check for driver updates on a separate PC, then transfer these to the faulty PC via USB stick to see if it starts to behave? I'll try that but then again, if I reset the PC to original state as I did, wouldn't the drivers be ok then, I mean the pc did work the first time I started it just over a year ago and the reinstalled Windows is the same as the original as it comes from the pc harddrive and as I don't have a network connection. Do I miss something here? Kind regards Christian

    How did you reset the PC? Did you delete the all drives (like C:, D: etc.) and then again partition the HDD in separate drives then installed the OS after full formatting? Please clear this confusion. Now you don't have network/internet connection, as you ,mentioned. So how did you activate the Windows 10 Home Edition? What is media that you used to reinstall?

    I had that exact same issue, and it was caused by a faulty patch that Microsoft issued. Have you tried bring up the system in safe mode and then go into the History of the patches and see if there are any that failed in the history. If there are then remove them. Just because they failed, does not mean that they did not partially install and now causing the system not to boot properly.

    While you contacted HP, take all necessary backups, if any and then follow their instructions. Probably they can tell to you do some diagnose as per their instructions either over phone/email. It is better to go for delete all partitions (before that, take backups) reformat the HDD & then make partition according to your choice. Before partition/format, make sure you have right OS with valid license. Hope, this will be helpful.

    Because you did a reinstall I don't think you can recover from an old restore point. That is always my first choice when a new patch or something trashes my system.It's much easier than having to to the install and then reload drivers, make all my custom setting again or possibly losing some data along the way. Keep us posted on your progress.
