No picture with Z270F

[Shetani]

I have had so many problems so far swith this build.

Parts list:
MOBO: Asus ROG Strix Z270F Gaming ATX, Socket 1151, Intel Z270
Memory: Corsair Vengeance LPX DDR4 2666MHz 16GB
CPU: Intel Core i5 7600K 3,8GHz Socket 1151
Cooler Corsair I45
SSD: Intel 600p Series M.2 2280 SSD 256GB (Firmware upgraded)
GPU: Asus GeForce GTX 1070 Dual 2xHDMI 2xDP 8GB
PSU: Corsair CX650M
HDD: WD Black 1 TB

I had it working with windows 10 home installed, then I did a bios upgrade to the newest 0701 and started getting lots of BSOD
Reinstalled many times but it just got worse and worse, so I did a memtest86 and found memory faults and the test kept freezing up. So i returned and got the memory modules listed above. But not sure if they was the fault after all...
I did a Bios reset one time who went fine, then second time I got no picture on monitor. I have no tried to take out the CMOS battery, didnt help.
I have tried with no GPU, didnt help, I took my old AMD 7970 from my other older gaming PC and tried that, didnt help.
The PC starts with no error beeps and no LED`s that should say anything is wrong.
The next thing is to maybe remove thge m.2 SSD and see if that does anything.

Help needed.

None of the QLEDs remain lit when your system halts with that error?

No everything looks to be operating normal, so weird. No beeps, no error leds. No picture at all. When i switch my DVI cabel from Built in to gpu it just shows going to sleep mode on monitor.
Contacting Asus tech as soon as they open. This sucks, my son is supposed to be going to a lan party today...

I am going to try one more try to reset BIOS, after reading the manual i see they have a little different way of doing it. Or I should leave the battery out for much longer then I did. I just had it out maybe 20-30 seconds and now I see that it should be more like 30 minutes.

Have you tried testing with another cable or monitor?

The monitor is fine, and everything worked before I did BIOS upgrade, after that trouble started and it has slowly got worse and worse. Sending the motherboard back. Maybe I go back to Gigabyte never had any trouble with products from them...
