Hello, first time builder here. I recently bought PC parts and put them together (thought I had it correct, but turns out I didn't) when I run the PC, the GPU, HDD, and system fan seemed to be working fine then after 5 seconds the PC shuts off and restarts itself 1 second after (nothing displays on the monitor). At first I thought it was the RAM because because getting it in was a little tough (sometimes it was loose in place the slot). I removed the GPU and tested it, same result, so I removed the HDD and tested it, same result.

Maybe my motherboard/psu wiring is wrong? I am thinking about thoroughly watching more videos & planning out what goes where then deconstruct it & try it with testing this time... I can provide imgur photos if needed.

My build:
Motherboard:GIGABYTE GA-H110M-A (rev. 1.0) LGA 1151 Intel H110
CPU: Intel Core i5-6500 6M Skylake Quad-Core 3.2 GHz LGA 1151
GPU: GIGABYTE Radeon R9 380X
RAM: G.SKILL NT Series 8GB (2 x 4GB) 288-Pin DDR4 SDRAM DDR4 2133
PSU: EVGA 100-B1-0500-KR 80 PLUS Bronze 500W Active PFC ATX12V
HDD: Seagate Desktop HDD ST1000DM003 1TB
CASE: Corsair Carbide Series SPEC-M2 Black Micro ATX Computer Case

I JUST made PROGRESS!! WOO. I pushed my RAM in so hard to where I couldn't see the gold things at the bottom anymore and now the PC is on forever. I'll hook up my monitor and check things out now.

edit: BIOS is up.


Yes, I connected it to the GPU. It lights up and the fans spin until everything shutdowns. I even removed the GPU and got the same result. I hope the PSU isn't the issue here, but I can see what you mean. Still, it should have been able to power everything without the GPU there.. I'll def replace that later this year (or sooner, hopefully not, haha). I really hate the PSU because it's so hard to work with...but you get what you pay for.
 
The RAM is not compatible with that motherboard. The RAM you have is 288-pin DIMM form factor, but the Gigabyte GA-H110M-S2PV DDR3 (rev. 1.0) Micro ATX LGA1151 Motherboard only accepts 240-pin DIMM form factor RAM. I would also recommend going with at least a 550 - 600 wattage PSU. That GPU you have alone recommends a 500 watt power supply.
 


I find it too. I saw reviews for this motherboard & folks said it was a little tough to get the RAM in place. I see no POST info. I noticed when I had the HDD plugged in it made a little bzz sound once (can't remember the exact sound, tested 10 hours ago). When the GPU & HDD is taken out, the machine powers on & off silently with the noise of the system fan spinning.

Thanks for the link. I'll go through it 1 by 1.


 

Is this really the issue? I hope so, haha. I was afraid my parts were defected or something.. but since I'm a newb, it'd probably my own fault. While I was choosing things on PcPartsPicker, it indicated that everything was compatible, guess not.

edit: I just caught it, but what you wrote isn't my motherboard. ah :/
 


You must have looked up the wrong board. His build is compatible.

I certainly may have. There are 4 versions of that motherboard, so I must have looked at the wrong one. I searched for the name of his motherboard and only one came up on PCPartspicker. But Newegg is showing 4 versions.

I do apologize for the mistake and thankful that you caught it. Still, I am curious as to why the RAM is hard to install.

Here's what came up for me. https://pcpartpicker.com/parts/partlist/
 


I don't have a paperclip, but I do have a "24pin PSU bridge tool black" that came with the PSU. Will that work?
 


I can buy some in 15 minutes. It's a shame I don't have basic office supplies.

edit: I found a paperclip under the couch....
 


I just tested the PSU and it works with the paperclip. Had it running for 30 seconds then turned it off.

Not seating the RAM properly is a common mistake. Now you will know the next time you have to install some RAM that you have to use a little force.

I helped a guy on here not long ago that had actually placed one of his RAM sticks in backwards. Yup! Backwards! :pt1cable: He posted a pic and I noticed right away it was in there wrong. He took it out and properly installed it and was finally able to get his computer to boot.

Enjoy you new build.
