I doubt that your problem has much to do with the Adobe installation other than that there was a restart involved. After the RAM check the POST checks all remaining system hardware - if won't run past the RAM check then there is either a hardware malfunction or a BIOS software error.
You could check the former by turning power off and replugging all hardware, removing unnecessary devices to see if you can achieve a basic boot. Suspect a hdd....
Check the latter by using F2 to set BIOS defaults [you will lose your customised BIOS settings unless you have saved them to some medium, assuming you had that option...]. If F2 does not work try swapping the mb battery power jumper or pulling the CMOS battery itself for a minute or so.
