Hp omen black screen?

[ecorey120]

my hp omen 15-5268nr Bought 2nd hand worked great for the first few months of use but suddenly for no apparent reason once powered on all lights and the fan power up but the screen remains black for an extreme amount of time like 30 min before booting to the os. I’ve restored the windows 10 os to factory ran the memory diagnostic test and didn’t detect any problems. Last bios boot time shows more than 1300 seconds every time I boot. I don’t know what to do it’s not hardware since it does boot just not in 10 seconds anymore it’s 30 min

@ecorey120Not sure I can solve this but I'll offer what I can.

To clarify, 1) once the screen shows activity, Windows is actually going thru the steps of starting up or 2) once the screen comes on, Windows is already active?

Also, did you create the HP Recovery from the pc onto a USB drive and clean install from that? No other software was added from that point and the scenario still exists?

If the first scenario, I would suspect a bad hard drive. Make sure the drive is securely seated in the slot by opening the case and removing it and reinserting it. If that doesn't help, You would need another M.2 drive to test with. Install the drive and use that HP USB Recovery drive you first created to add Windows again (or the latest windows version with the MS Media Creation Tool).

Boots windows goes through the entire load screen. 

I didn’t use a usb to reboot used windows recovery for a clean install 

bios boot time is consistent at 1300+ seconds every reboot

Your terminology is a bit confusing. Windows Recovery... if you mean you did a Windows recovery from with-in windows itself is not exactly a "clean install". A preferred way to clean install would be from either an HP USB recovery drive you would boot from, or a Microsoft USB media installer. This would wipe the drive completely of all its partitions and start completely over.

I would recommend one of those 2 methods. The MS Media Creation Tool would give you the latest edition of Windows. Go into the bios and reset it first (Edit, I dont think the 5000 series had a cmos battery. If it does not have a coin battery, unplug the main battery for a while). Then run the installer. You would simply need to choose a Custom installation when prompted and delete all the partitions first, then let it continue.

If you can get your hands on another M.2 drive, I would try installing Windows to that. If that does not fix the situation, there is something physically going wrong on the motherboard or some other hardware part of the computer.

You could run Memtest from USB and test the memory. The memory is hard soldered to the motherboard and if that is testing bad, you cant just replace it unfortunately.
