Newly built PC not booting/powering

[Anzillu]

Hello, I just recently bought several upgrades to my PC and needed a new case as well to fit this new hardware. The problem is I have everything plugged in correctly and unplugged and replugged them in. My PC powers for about 1 second-all the fans and lights come on- then turns off.. my specs are:

MSI z97 gaming 5 Mobo
GeForce GTx 760 gfx card
4x8(32) GB corsair vengeance ddr3 RAM
EVGA gq 1000 watt psu
Intel core i7 4790 LGA 1150 processor
Ihas-c odd
Stock 1tb SATA HDD from old PC

I'm not sure what the issue is, before I replaced the processor it would stay on but not output any display. I replaced an i7 6700k LGA 1151 with the one listed above. Any suggestions would be appreciated. Thanks

"I replaced an i7 6700k LGA 1151 with the one listed above.'
The Z97 does not support LGA 1151 CPUs. How have you replaced the i7 6700k?

 

[Anzillu]

I'm not sure, I bought the processor not knowing it wasn't compatible, it didn't fit in perfectly so I figured I should replace it. This 1150 fits but for some reason not staying on when i hit the power switch to turn the PC on.

Is the 8 pin power cable connected to the motherboard?

 

[Anzillu]

I do not have an 8 pin connector or spot on the Mobo for one. Are you referring to the ATX from the power supply? If so then yes. I have everything from my case plugged into my Mobo.

Ok, I found a cord and the 8 pin slot on my Mobo.(I must be blind). Now my PC turns on and is booting on and off.

If removing all RAMs and starting the board, still on and off?

I just removed the RAM and it stays on for about a minute then cycles and then stays on again.. still no display being output

Now power off and insert single RAM module (graphics card removed). Start the board and see if getting signal on the monitor.

Ok I'm getting display now with a single RAM in it. Do I plug my gfx card back in and try again?

 

[alexoiu]

Now power off, insert the second one and test again.

Ok process of elimination. I think I'm good now. Thank you for your help, much appreciated.

You're welcome.

You're welcome.

A little update- seems only 16gb of RAM work, I tried the other two slots and they seem to not work. Is there anyway to fix this?

 

[alexoiu]

It might be a bent pin in the CPU socket, or an over tightened CPU cooler.
If leaving single RAM module installed and testing each slot, do all of them work?

It seems the right 2 RAM slots do not work, I tried a single RAM in 3 & 4 and PC just boots on and off. my first two slots work, so I'm running 16gb now.

 

[alexoiu]

A bent pin, I'd say.

 

[Anzillu]

A bent pin, I'd say.

I looked at my processor slot, and none of the pins are irregular, I'm fine with 16gb ram, just wish I could use the full 32 I had bought

Can you post a picture of the CPU socket?
