Asus Prime z270-A, wont automatically restart

Hey,
I just recently decided to build a new pc. Among other things, I bought an Asus Prime z270-A motherboard and i5 7600k CPU. I had a lot of problems installing windows on, but I finally got it to work(Windows10).
Everything works fine, but when I want to restart my computer, it wont start up again. The computer is making noise, fans moving, gpu lights on, but the screen is black and says no signal. My mouse/keyboard lights are also not on. When I forcefully shut it down and start it up again, the computer starts in BIOS safe mode. I can press F1 to get to bios.

Here's the weird part. If I set my boot device order to #1 Windows boot manager and press F10 to save and exit, it says nothing was saved, restarts the computer, but I get no picture again and the message about no signal.

Now, if I shut the computer down again from the power button and start it up, I still get the bios safe mode message. I press F1 to go to bios, I then go to boot options, but go straight to "overwrite boot option" and choose the "windows boot manager" from there, it starts windows fine, without a problem, but when I want to restart my computer again, I get the same black screen all over again.

Does anyone know why it keeps doing that and how can I make it to automatically boot to windows? I have tried disabling other boot priority options, but get the same outcome.

Is the board in the default mode? I had a problem with my first 270-A, 2 bad memory slots and then when I'd try to put in the X.M.P. profile for the RAM it wouldn't post AT ALL, just sits with an orange and red light alternating on the board (should flash a single white, then green for the memory check, then post).

I'd have to hard shut off the computer, then press the button to start it up and the board would enter safe mode. Took the X.M.P. out and I get into Windows fine. After I was able to manually put in the RAM speed but since the other two slots were bad I still ordered a replacement.

Long story short I'd get a new board. If you have every boot option disabled save No 1 being the Windows manager partition on whichever drive has your OS you shouldn't have that problem...unless of course you can't save changes to the boot menu in which case you'll be screwed without the over-ride regardless.

Sounds like it works it's just the ability to save your changes to the boot menu being gone is the problem.

Try changing something else on the board and then booting to Windows manually like you describe. Don't log in...just shut down and power the computer back on manually. Enter the BIOS and see if your changes saved.

If it says "no changes were made" and when you boot back up to check it for sure didn't save them...you know what the problem is. The board won't take any changes.

Hey, I turned the XMP profile to auto instead of whatever was there and it worked like a charm. Restarted right into windows. Thanks a lot for your help man, it really brightened up my day, after 2 days of headache with this entire situation to get my pc to run :)

No problem. I think it has to do with the "advanced settings" the board tries to apply under the X.M.P. I was coming from an Gigabyte BIOS before this one so it's a lot different and I thought letting it do it's own thing would be the best bet.

When I have more time I'll set up the new board manually with an OC after I figure out the BIOS a little better, but for sure I know the X.M.P. thing wreaked havoc on mine.

I still had bad slots though so I got a new board. I'll be messing with that this weekend and report back if I find out anything different. You should be able to go into setup though and in advanced mode set the RAM speed manually (without X.M.P.). I have 3200 and I think the board runs 2133 by default. Manually entering 3200 in the "Advanced Mode" (Hit F7 if you have the E.Z. Bios enabled) without the X.M.P. caused zero issues for me.

Good luck.

I think I found the main issue. I have 2x 8gb Patriot Viper 4 DDR4-3000 MHz memory. So I went to set the speed to 3000Mhz in bios and it didn't boot. I then set it to 2800Mhz and it booted up fine. It won't make almost any difference, but I'm wondering if something is faulty or it's misadvertised. I'm not very knowledgeable about ram, does the SPD option show, it just needs more voltage for the 3000 MHz speed?

EDIT: Oh I did some reading around and I realized I have to do some overclocking to reach 3000Mhz :)

It looks like you may need to increase the voltage to 1.35 to reach 3000? When you run 2800 and are in windows what voltage is on the RAM?

To be honest I'm not sure about overclocking RAM...i'm running Corsair Dominator in my board and I can just run 3200 without changing anything else other than the manual clock setting. Never even looked at the voltage setting.

No way you'd notice the difference in 2800 and 3000 anyway.
