I have an HP desktop with an I-5 processor in it. I can get into the BIOS and make changes there. My problem is that the computer will not go any further or run any programs. The hard drive is blank and if I try to install windows 10 from a DVD, the program will not run. I tried to clone the machine (I have several of them) with an image I have using Acronis. The Acronis program will boot fine from a USB drive but as soon as the Acronis program is up and running at boot, then everything freezes. I cannot use the keyboard or mouse. I already flashed the BIOS. I have tried both USB and PS2 keyboards and mice. I have switched out the RAM with another machine. Any other thoughts on this other than a bad motherboard or CPU? Am I missing something here?
