I am sorry to hear about the trouble you are having with your build! First I would like to say I do not mean to offend if I mention something extremely basics. Typically build issues are caused by over looking the small stuff. I have done this myself many times and I build networks during the day! I would recommend that we start with the basics. I would setup the computer so it only has the PSU, motherboard, CPU and one stick of memory. Utilize the mouse and keyboard in the back USB ports, preferably the non-USB 3.X ones. (non blue). Use the on board graphics Please make sure the PSU is plugged in the 24 pin connector to the right of the memory and the eight pin to the right of the PS2 connectors. Also, make sure the liquid cooling fan is connected to the Four pin CPU FAN connector located to the right of the 8 pin PSU connector. Most motherboards have a safety feature that they will not initiate POST without this connector plugged in. Please let me know if the system posts.
I understand completely. No worries. Have you tried to clear the RTC RAM?
To erase the RTC RAM:
1) Turn off the computer and unplug the power cord
2) Use a metal object such as a screwdriver to short the two pins. (It is located at the bottom of the Motherboard marked CLRTC)
3) Plug the power cord and turn ON the computer (With the two pins shorted)
4) Hold down the <Del> key during the booth process and enter BIOS setup (If it gets that far).
Please let me know if this action provides any results.
Also, just re-reading your notes from before, does your second machine as noted a sixth generation motherboard as well? Would it be possible to try your new i7 on it?
As I was researching, I noticed that there are multiple BIOS updates that indicate support for newer CPUs. Perhaps you could use the i5 in your second machine to get the motherboard to BIOS, and perform the H170M-E D3 BIOS 1802 update located at:
I want to make sure that I'm providing you with a complete list of things we can try before having to contact ASUS tech support.
I completely understand your concern. As I knew your motherboard was new, I copied those instructions out of their manual.
I understand your concern. It was meant to merely see if you can get past the post and to the BIOS. Perhaps seeing if the i5 would work on your new motherboard might be the best option at the time. I hope you have a good night.
Please let me know if you have made any progress on this issue. If not, we can go back to the drawing board and work on other resolutions.
Glad you found the answer to your issue. Hope you have a great day.
