BIOS boot order is set to the boot drive?

The ATX_12V_2X4 8pin power connector is plugged in completely?

reset the BIOS by jumper

In which slots did you install the RAM? Dimm slots A2 and B2 would be recommended

SSD firmware is up to date? Use Samsung Magician to check and if available, update the SSD
In which M.2 slot did you install the 970?

In which SATA port is the 860EVO plugged in?

Did you install windows freshly?

Update the BIOS of the motherboard to the latest version: F10b

Also ive noticed that this problem is described in the last version of my bios, And mine is 2 versions behind. Also i cant open it so i have to use flash memory and do it on boot or however they do it.

Much appreciated!!

Fixed it it was the bios, so after updating the bios it gave me error that some of the configuration is not right, so i went into the settings and set all my CPU , Ram , voltages to AUTO, and that fixed everything. My PC starts up from first try quick, and yeah everything seems fine. Thank you so much for the quick response!! I really appreciate it.

Another thing that i find weird is my ethernet cable network. After my PC starts which is about 5 seconds it takes about 15-20 seconds for my ethernet network to start, my wifi is working on startup but my ethernet takes a little longer.

reset the BIOS by jumper (clear Cmos)

any firewall or antivirus software installed?

Is the ethernet network set to private and not public?

Drivers for the LAN chip is up to date? Try different drivers

i didn´t read your post carefully
wifi and lan at the same time won´t be working well together most of the time, like you managed to sort that out yourself.
