I've had my EVGA Z170 Classified 4 way for about 2 years and it's been working great up until the other day. I tuned it on and it was going through the post codes and it came to post code 35 then shut down and rebooted over and over again.
I switched to all three Bios settings and all three do the same thing. I tried the reset switch on all the Bios' and it did no good. I pulled out the CMOS battery and replaced it with a new one just in case and pulled out the CPU and even changed the thermal paste while I had it out.
I've had no problems before this and made no changes to the system or software at the time or before the trouble started and haven't overclocked anything.
My system is:
 
Operating System: Windows 10
Motherboard: EVGA Z170 Classified 4 way
Memory: G.Skill Ripjaws V, 64 GB DDR4 (4 stick kit)
Processor: Intel i7- 6700K
SSD Drives: Samsung 850 Pro 1TB X2 running in RAID 0
Video: EVGA GTX 980 Ti Classified X4 in Sli
Monitors: ASUS Swift PG278Q  x3
Keyboard: Corsair K95 RGB Platinum
Mouse: Corsair M65 Pro RGB and Corsair MM800 RGB Polaris Gaming mouse pad
Optical Drive: Pioneer BDR-209DBK Blu-Ray Writer (I removed this a while ago because I never use it)
Case: Corsair Obsidian Series 900D Super Tower Case
Cooling: EKWB custom water-cooling Loops for the CPU and a separate loop for the GPU's
Any help would be appreciated before I apply for an RMA.

Thanks but I tried that also.

Yea . also 2 sticks in 2 and 4 then 1 and 3. Sorry I forgot to ad that to my original post. 
Thanks for the help.

No, but I was thinking about upgrading to a 7700K for a while now. Held off because the difference between the 6700K and 7700K are minimal but I'm going to order one today.
I'll keep you posted. Thanks for the help.

Just wanted to let you know I decided against upgrading to a 7700K. Just not enough differences between that and my 6700K to warrant almost $400.00.
I contacted EVGA Tech support and got an RMA approval so I'm sending my board back for a replacement.
Thanks again.

Sure will.
