HP Recommended
Product: Z640 Workstation
Operating System: Microsoft Windows 7 (64-bit)

HP Z640 preloaded with windows 7 pro. Failed to boot ROM code 8 beeps. Has failed bios reload 3 times. Each time running over 8 hours. Replacing motherboard. There is no windows COA on the system case which would  indicate that the windows COA  is imbedded  in the bios. When we replace the motherboard the coa code will be void (lost). The system is out of warranty. It is running propriety software and will not run on windows 10. How can we take care of this issue?  Since windows 7 keys are not available?
