z370 Issues

[NoobieBuilder]

Hello, I'm a long time LukeTechTips fan in need of some help.

 

I saved up to buy all my parts but after putting it all together the motherboard leds only turn on for about 1 second then off again.

 

 

Parts are below

Intel - Core i7-8700K

Cooler Master - MasterLiquid Lite 120 66.7 CFM Liquid CPU Cooler

Gigabyte - Z370 AORUS GAMING WIFI (rev. 1.0) ATX LGA1151 Motherboard

Cougar - VTX 600W 80+ Bronze PSU

Corsair - Vengeance LPX 16GB 2x8gb

nzxt case

no gpu right now

 

no bios boot or anything

leds turn on for about a second when I flip the power switch on the psu

I tried the power supply on my old computer and it worked fine.

I can only ever get it to show the leds on the mobo for 1 sec.

I tried unplugging everything and just having the motherboard plugged into the power but I only get the 1 second light again.

I'm a noob so sorry if I missed something.

I really don't know if this is a troll or not

Dude.....I seriously need some help. This is my first custom build

The good news is that usually, LEDs turning on for a split second is a good sign as far as no booting goes.

Nine times out of ten, it means you've plugged something in the wrong place or seated something wrong. Check the CPU is firm in the socket and at the right angle. Reseat the ram. Check PSU connections, check literally everything. I'm almost certain your build is fine, you've just plugged something in wrong.

I've had this problem on a build I've done before. Everything plugged in right, parts were all fine, and the thing that fixed it was when I reseated the GPU about 10 times.

This could mean the psu is self protecting due to a short. Check to make sure the back of the board isnt shorting out on the case.

Thanks for the replies. I will try the re-seating the cpu like @Armakar suggested.

 

@JrockI tried with just the motherboard and psu without the case in the motherboard box and the same thing happened. Does the cpu/cpu cooler and at least 1 ram stick need to be in for it to boot? If the case did cause a short would the motherboard be dead at this point?

 

Thanks guys

System will likely need the fan plugged in for the cpu, and probably a stick of ram. Try a different stick of ram, unplug any storage device, and try without a gpu in the system. If it posts, then slowly 1 by 1 add items back to the system.

 

Oh also try a different psu if you can.

[NoobieBuilder]

Thanks for the suggestions. I'll report back after I give it a few more tries.

I finally got it to post with a new stick of ram. Is there any way to test if some of my ram slots are dead?
