Hi there @crazywolf14
Welcome to the HP Support Forums! It is a great place to find the help you need, both from other users, HP experts and other support personnel. I understand that your computer is no longer starting properly, and is stalling on a blank screen. I am happy to help.
I suggest you start with this and follow the recommended process. There is a section for a not starting and getting to a blank screen. HP Desktop PCs - Computer Does Not Start (Windows 10,8)
Have you tried a different keyboard, or verified that there is not a problem with the existing one by testing on a nother computer?
Let me know how that goes for you, or any additional errors or glitches that may occur.

Thanks for the reply.
I once got to the HP recovery screen.
I was able to confirm that the hard drive is detected in BIOS
I was able to do a hardware diognostic start-up test and all hardware checked out OK.
Now I am back to the beginning of the problem again.
I get black screen.
No HP recovery screen
No Windows recovery screen

I am having the same issue.. Power light comes on fans come on, screen is blank and none of my ports don't work.. I can't even plug in another monitor since there's no power to ports or keyboard or mouse.. I did everything like reseated ram, pulled the tiny battery,, I posted this yesterday on here and no one has replied to my post

Any activity here? I have exactly same problem..... power light comes on, fans run, blackscreen and no usb port. Lack of usb ports confirmed by no led on the mouse/keyboard device powered by usb. Without keyboard, no way to troubleshoot per HP support. Also tried different keyboard/mouse device.

I am still still dealing with the same problem....One repair guy said that the pc may not be getting enough power to run the pc... It may be the power cord is bad.... I haven't purchased a new cord as yet to see if it fixes the problem... also, check the ram & maybe replace with new ram....If you find an answer I'd love to know....

This seems to be a big problem......It seems HP would let one of us send in our PC so they can diagnoise the problem & send out a fix solution for everyone... Beings it could be a lot of different things or maybe just one thing, The guessing game is wearing me out !!

Hey dont know if this helps, but i had the same issue and tried everything above ^. I solved the issue by reseeding the 4 pin power connecter to the motherboard. Must've been knocked loose somehow. Just unplugging it and plugging it back in it solved the issue.
