Hi,

Before posting here I have searched the forms and tried everything but didn't couldn't find a solution. I'm looking for my knight in shining armor to help me with this please. Here is my build :
-Intel - Core i7-6800K 3.4GHz 6-Core Processor
-ARCTIC - Liquid Freezer 360 74.0 CFM Liquid CPU Cooler
-Gigabyte - GA-X99-Gaming 5P EATX LGA2011-3 Motherboard
-MSI - GeForce GTX 1070 8GB Video Card
-Crucial - Ballistix Sport LT 32GB (2 x 16GB) DDR4-2400 Memory
-Corsair - Carbide Clear 600C ATX Full Tower Case
-Thermaltake - DPS G RGB 750W 80+ Gold Certified Fully-Modular ATX Power Supply

The first time I built everything and when I turned it on it enters an infinite cycle of on and off. Lights come on , fans turn on for about 2 seconds and then they turn off. The PSU makes a tick sound and then one beep and turns off. According to my motherboard manual one beep means everything is okay. Yes I connected power to the cpu and to the motherboard.

I removed all the components and only had the PSU, MB, CPU connected and the same problem continued. I added one ram stick and tried all slots and the problem continued. I tried connecting the GPU and hdmi cable to it but I don't get any display and everything keeps turning on and off with only one beep. So far nothing has worked. I tried removing the battery on the motherboard for a while and reconnected it but the issue continued.

Could be a lot of issues, have you tried taking the cpu out and putting it back in? Make sure the cpu cooler is fit tightly! One possibility could be that the cpu is reaching a high temp and forcing the computer to shutdown to prevent overheating. It is possible that the computer then restarts and runs into the same issue in an infinite loop. Also, the cpu cooler slot on the motherboard often has to have something plugged into it. So you could also check that. If not, the mobo will think the cpu isn't being cooled. Also, make sure the cpu is lined up correctly and pins are straight of course.

I assume you tried switching wall outlets. U never know! I'm guessing you also made sure everything was plugged in nice and fit. I have seen...

thanks for the quick reply. I don't have another psu unfortunately but I turned off the lights and haven't noticed any sparks of any kind coming from it. The tick sound happens --> computer turns on for two seconds-->Beep and turns off. Then it happens again starting with the tick sound. I will see if I can get my hands on another psu to try it out.

I did and I even removed the motherboard and put it on a piece of cardboard away from moving parts and I was getting the same results.
 
Does that GIGABYTE GA-X99-Gaming 5P (rev. 1.0) motherboard have BIOS Version F22 or later installed? F22 or later is required for Broadwell-E processor support.

If the BIOS version is earlier than F22 you may have to borrow and install a Haswell-EP processor to flash the BIOS to a later version.

I checked the psu using the paper clip test. The psu turend on and stayed on . The tick sound I guess that is the
sound in makes when it turns on. However, the PSU has RGB and they didn't turn on I'm not sure if this means anything or not.

Could this cause this behavior ?
 


It certainly can.

Without the BIOS update, the motherboard might behave unexpectedly, and possibly might not even boot up with the new CPU, even though there is nothing wrong with either piece of hardware. Manufacturer recommended and provided BIOS updates are the solution that is required for this situation.

The possibility that you have a defective motherboard also hasn't been ruled out.

If you have a multimeter, you could also try testing the power supply plugs. Multimeter is super cheap at your local hardware store and it's very easy to test the voltage.

Oh, and check that your case connectors to the motherboard are lined up correctly. It's really easy to mess those up since they are so small. Probably not the problem, but yet one more thing you can check off the list!
