Hello,
3 beeps stand for a RAM problem.
1/ Plug only 1 RAM stick in DIMMA2 (2nd DIMM slot from CPU) and do a clear CMOS:
- Power off PSU, unplug the power cord and wait that all mobo's leds light off.
- Keep the button on the back panel pressed during at least 30s
- Plug the power cord and power on.
- You would see a message. Choose to enter in bios setup then
   set only "SETTINGS \ Advanced \ Windows OS Configuration \ Windows 10 WHQL Support" as "Enabled", change nothing else.
Result?
2/ Redo #1 but with the other stick in DIMMA2.
Result?
3/ What is your current bios version?
Hoping it shall help,
:hat tip:

In that case, it is not a RAM but a graphic problem.

Yes, you can now plug the 2 RAM stick in DIMMB2.

:undecided: It can explain the beeps: bios V2.80, who has been built only to "support new upcoming AMD CPU", has many bugs for current CPUs! :undecided:
With a such problem, I would go back to the previous version. Unfortunately, AMD (not MSI) refuses any downgrade from V1.60 so that you cannot do it with M-Flash. Fortunately, the tool >>Flash tool[1.06] for MSI UEFI BIOS<< (https://forum-en.msi.com/index.php?topic=302638.0) is able to do it. Use it to downgrade to >>Bios V2.60<< (http://download.msi.com/bos_exe/mb/7B78v26.zip) (E7B78AMS.260). It is a reliable tool developped by one forum's administrator and it saved many users.
Have a good day,

I don't know if this is helpful to anyone after such a long time since the last post, but I just wanted to pipe in that I have been having the same issue with the 3 long beeps at bootup. - At first, I assumed it was a RAM issue and even though I was not overclocking, I would reset the BIOS, boot back up, and then change my settings.  However, I have discovered that this appears to happen pretty regularly when I have my XBox One controller plugged in to a USB port when I boot the system.  If I power off the system, unplug the controller and boot back up the system boots normally.  But if I happen to forget the controller is plugged in when I power off after playing a game and boot back up with it plugged in, 9 out of 10 times it will again give the three long beeps, and just like clockwork, if I make sure the controller is NOT plugged in when booting, it boots normally. It doesn't appear to matter which USB port it is plugged into, only that it IS plugged in.

This may be totally unrelated to the above posts, but I just wanted to throw this out there since it was similar in regards to the three long beeps with the machine not booting.

I am running an AMD 2700X on the MSI X470 Gaming Pro Carbon with 16GB of Corsair Vengeance LPX 3200 RAM, and an MSI R9 390X video card in case anyone needs that information for comparison.  I am not overclocking anything, and using mostly defaults other than I turned off the splash screen so that I can see the POST messages, and disabled onboard sound since I am running with a Soundblaster ZX soundcard.
