The thing is, if it's an HP laptop, you can only use the drivers provided by HP. If you're running the latest drivers, the only thing you could try to do is reinstall them.
Something else it could be related to is your WIFI connection. The delay in WIFI connectivity may be causing the delay in boot up, and the black screen. I'm not sure how to resolve that issue.
Perhaps a more experienced forum member will chime in with some advice.
I've been told leshcat continued the line of display drivers for my graphics configuration. I've tried them and they were unstable (graphical artifacts, especially with html5 videos) and did not contribute to solving the problem.
I think it's pretty safe to assume it doesn't have to do with my display drivers.
Thanks for your reply. My laptop is not HP. It is Lenovo Z580 .
Are you on a domain, have mapped network drives, or running antivirus?
Thanks for your reply.
I am not on a domain and have not mapped network drives.
I have MSFT Security Essential as antivirus. If you read my thread, you can learn. I am not able to boot my computer.
Thanks for sharing.
I just solved this after a month of trying all the advice I could find out there. The clue with Performance Monitor was that during the cca 40 second delay there was minimal CPU activity, so logically switching off boot-time programs, services and processes was not going to do it. Which it did not. The diagnostic breakthrough came with running Sysinternals Process Monitor boot logging (nicely explained here Using Process Monitor to Solve a Slow Boot Problems | Windows OS Hub (woshub.com) and I found that I had some inexplicable twice-over 20 second delay in winlogon trying to create some font, specifically Lato-Regular.ttf in the Windows\Fonts directory and getting ACCESS DENIED. So I thought I'd uninstall it, but it was not visibly there in the directory. So I thought I'd install it and then uninstall it, and it told me it was already there (!). So I created a restore point, went to regedit in administrator mode, looked for the ttf entry and found it under Fonts along with all the others that were normally visible, (see e.g. the guide here How to Delete Fonts using the Windows Registry - Make Tech Easier) deleted it, despite the standard warning, and rebooted. Hey presto!
