This has happened to 4 different computers that I have encountered in the last 10 months.
One was a Windows 7 computer, the others Windows 10
They all have ASUS mobo and freeze at the ASUS F2/Del screen on startup
If I remove the hard drive, the system boots to BIOS ok
If I put the hard drive in a system that was working fine, the F2/Del freeze issue happens
If I put a known good hard drive in the system with the freeze issue, it starts fine
I have tried the CMOS battery reset
I replaced the mobo on one system
I tested different RAM on one system
If I connect the hard drive to another computer using a USB enclosure, it is readable and I can copy files; just won't boot
Thinking maybe the Windows is corrupt or has some weird virus. Any suggestions to try to fix without having to reformat and reinstall Windows and programs?
