Hi, just recently upgrade to ryzen 5 3600. Motherboard is MSI Mortar Max. Using ssd wd black sata.

Fresh boot can take as long as 2 mins. Restart would take about 30 sec, much better. But my previous system i3 7100 take shorter than that.

Tried everything I can find from the internet. Change from CSM to UEFI, disabling all other boot option, update latest bios version, latest amd chipset driver. Now I just reset to default, and change csm to uefi.
   

Yes, I had the same issue with my previous MSI mobo.

I believe it is the MSI board.
The issue resolved after I changed to Asrock mobo, with the same NVME SSD.

Yes think so as all people facing same problem are using msi mobo. But now around 30 seconds is so much better than before.

Hey Guys,

New to the forums but experienced the same thing the rest of you had. Now, what was strange was when I first built my Ryzen 1700 with the MSI B350M Mortar Arctic everything was great! Boots were fast, crisp... updating was super quick. I was completely in love and happy to move away from my 6600k system. However, after using the MSI Command Center and changed CPU voltage setting that is where all my problems began. The moment I hit "apply" the system went dark, then booted back up into the bios. It seems from that moment on... POST started to take close to 20 seconds. Once the Windows logo was up, it was ready to go.

My second problem, though probably unrelated... Gears of War 4 would crash after just 10 minutes of game play. Every time I got a blue screen hinting at memory as being the issue.  I thought, well, maybe I just need to re-download Gears and try again. So, after several crashes having tried different things I uninstalled Gears and reinstalled it again. Same thing. The odd thing was that the rest of my Steam games wouldn't crash, not a one. DOOM, Street Fighter 5, Neir Automata (and it's known to be buggy), etc. Only Gears!

So that is when I started looking into thinking I may need a BIOS update for Ram compatibility and general fixes. I've updated the bios and still had the same 20 second boot time. Crazy. Another user suggested that perhaps storage could be the problem. After the update I reset the bios by removing the battery and killing all power to the system. So I unplugged all drives plugging them back in systematically powering the system on first to see what happens. And guess what, boot times came back to normal. My OS drive is a Samsung 850 Evo which I plugged in first. Rebooted, then plugged in my OCZ 400GB Steam SSD, normal boot still. Then my 2TB WD drive... and you guessed it... no more odd issues.  I haven't tested Gears 4 yet after the bios, I will soon. But at least for me.... completely resetting the bios, unplugging all drives and testing one by one worked for me.

*****TRY RESETTING YOUR BIOS AND REMOVING ALL DRIVES TESTING SYSTEMATICALLY EACH ONE*****  Hope this helps someone.

Wonder if taking out* the CMOS battery can fix the problem?
