I did something to screw this computer up!

I just built a new system with an Intel Core i7 6700k, GIGABYTE Z170X Gaming 7 motherboard and a GIGABYTE R9 390 GPU. I also have a Samsung 950 PRO M.2 SSD (boot drive) Samsung 850 PRO 2.5" SSD and Windows 10 Pro.

I first got all the parts and built the system and everything worked fine. I installed Windows and began running burn in tests on the GPU. The computer was great. Then I received my Corsair accessories like my light bar upgrade kit for the Dominator Platinum DDR4, blue individually sleeved DC cable kit for the AX860i and a front I/O panel for the Obsidian Series 350D(it was for a USB 3.0 exchange on my 650D case).

So after I changed out front USB 3.0 port cables, swapped out all the cables running into the PSU, and changing the light bars on the DIMMs, I put it all together and I got nothing on the motherboard. The system wouldn't even start up. In fact, none of the LED lights on the motherboard worked. So after playing with some cables, I got the lights to work, but then the system would shut off and restart automatically. So I changed out the motherboard and GPU. I then put the system back together and it still wanted to reboot automatically. I then waited 2 weeks to exchange the RAM, but it still does the same thing. Finally, I just swapped out the Corsair H105 AIO cooler and still the same thing. All the lights come on, all fans start, the H105 looks like it's starting, but then after 5 seconds, it shuts back off.

At this point I'm wondering if the Isopropyl Alcohol I used to clean my beautiful 6700k killed it. So to recap, I'm not getting any video and the system shuts off and restarts automatically. Any help is appreciated.

Thanks

What power supply?

Have you tried booting it without plugging in all the accessories you added?

Also try a minimal, just CPU, CPU fan, RAM, and whatever you need for graphics (I would suggest onboard graphics to start). Also make sure all mounting holes have standoffs and screws, which are secure (but not overly tight).

A Corsair AX860i. The mounting holes are secure, but I will try unplugging everything again and going that route again. Just don't understand why it worked well until I changed the cables.

Could be bad cables. Put the original power cables back in (and disconnect the light bar kit) and see if it fixes the problem or not.

yeah do this stuff ^

My thoughts are:

the power cables you replaced
or
ESD during your "maintenance"

thats just what comes to mind right away.

I will check the CPU cable, because it HAS to be that cable or ESD during the swapping of motherboards. Also, can Isopropyl Alcohol kill CPUs???

I would think that the alcohol could only be a factor if it got on some of the CPU contacts and was not dry yet, and you powered the system up.

OK, it's not the cables, so it has to be the CPU! I have contacted Intel and will get a new one from them.

OK, it's not the CPU either. Apparently its my 3,000 MT/s RAM and the fact the i7 6700k has a limit of 2,133 MT/s memory controller built in. So I guess I have to install some 2,133 ram and boot the system with that. Then go into the BIOS and adjust the settings so my 3,000 ram will work again. I didn't have to do that before, but I guess I have to now. Weird.
