Hi@NeonOverlon,
Thanks for stopping by HP Support Forums.
I came across your post and would like to help.
Need assistance in solving the multiple issues on the PC. Is that, correct? I will be glad to help you.
To help you with all the 3 queries you have, I recommend you to try the Windows update as well as HP Support assistant and check if you can perform any Video card driver updates along with HP BIOS update and check if the issue gets solved.
Also, if you have an alternate display, I strongly recommend you to connect it to the PC and check if the second display also has similar issues.
I was able to find the update for the video card and BIOS. Please use the links below and check if that solves the issue.
BIOS: http://ftp.hp.com/pub/softpaq/sp77501-78000/sp77850.exe
Video Card: http://ftp.hp.com/pub/softpaq/sp77501-78000/sp77726.exe
Hope the solution answers your query. Feel free to reply back for more.
