No Keyboard, Mouse, or Video on Cold Boot. I have an HP 3500 Pro, after upgrading to Windows 10 Pro from Windows 7 Pro. The issue started after I had changed the display settings to a resolution too high for my monitor. Windows 10 did not ask me if I wanted to keep the setting. The guy from HP in India, I think his name was Joe, could not tell me how to boot into Safe Mode in Windows 10 so I could change the setting. I finally plugged my projector into the Video port to change the setting. He had me reboot the computer so many times that it corrupted the boot sector of the hard drive. I bought a new hard drive, installed it, loaded Windows 8, because the OS disks that came with my computer were Windows 8, not Windows 7. I upgraded the computer to Windows 10.
Now, every time I shut down my computer, and try to start it, the Mouse, Keyboard, and Monitor are unresponsive. The CD drive opens, I get lights on my NIC, and when I plug a USB drive into the port, the light comes on, telling me the USB port is actually alive.
The only way that I can get it to boot is to, power down the computer, unplug the cord, reset the power supply by pressing the power button again. Next I reset the CMOS by moving the jumper, pulling the battery, and move the jumper and battery back. Next, I pull the Ram, and try to boot. I get the beep codes for no RAM. I shut it back down, replace the RAM, and battery, and try to reboot. This is hit and miss. Sometimes after continuous tries, I can get it to boot. Nothing works every time.
I believe I am having an UEFI issue with Windows 10. My understanding about UEFI is, that it does not read the CMOS to load devices. UEFI boots into sort of a last known good state. I go to the screen to troubleshoot UEFI, but when I try to reboot, it happens again, so I can't troubleshoot. Normally, a Cold boot, or Sleep does not cause the issue. Sometimes by moving the Mouse and Keyboard to another USB port it will work. Nothing works every time.
This document pertains to HP and Compaq PCs with Windows 8 and Secure Boot.
Secure Boot Configuration is a new feature of the Unified Extensible Firmware Interface (UEFI) in BIOS 8 that helps a computer resist attacks and infection from malware. When your computer was manufactured, UEFI created a list of keys that identify trusted hardware, firmware, and operating system loader code. It also created a list of keys to identify known malware.
When Secure Boot is enabled, the computer blocks potential threats before they can attack or infect the computer. For example, Secure Boot can prevent your computer from starting from illegally copied CDs or DVDs that could harm the computer. Secure Boot does not lock out valid recovery discs or Windows discs.
You may have to disable Secure Boot in order to use hardware (such as older video cards) that Secure Boot does not recognize, or to boot from a CD or DVD that is not recognized. If Secure Boot does not recognize hardware, Windows does not use the hardware when it boots up, and you may experience problems starting the computer. If Secure Boot does not recognize a video card, the computer may have a blank display.

I have been plagued by this issue for over 6 months. I am not sure how to fix it for good. Any help would be appreciated.
