Gaming PC stuck in bootloop

(Video of issue at bottom of post)

 

System specs: 

• 6700k 
• Noctua NH-D15
• Gigabyte Gaming 7 Z170
• G.Skil TridentZ 3400 Mhz RAM
• Zotac GTX 1070 AMP! Edition
• 2x SSD
• 1x 1TB HDD
• EVGA 650w G2 80+ Gold PSU 

Backstory: About 3 months ago, I had purchased an Oculus Rift and had a friend over to play around with it. We set everything up on my screened in porch for maximum play space. While playing a bowling game, my friend slammed his fist on the table my PC was sitting on by accident, and it immediately froze up and started making an awful electronic glitching sound ("MERRRRRRRR"). Hitting the reset switch did nothing, so the only thing I could do was flip the PSU switch and reboot. It sat there and boot-looped for about 10 to 15 minutes before it finally decided to post and boot. 

 

Ever since then, the same thing will happen even if the PC receives minimal shock. For instance, letting my mouse down a little too hard is enough to set it off. The audio doesn't always glitch out too. And 95% of the time, the only thing I can do is flip the power switch and let it bootloop for a while until it finally boots.

 

The only step I've taken to resolve the issue one my own is a complete rebuild. I tore the PC down, checked everything from connectors, to cables, to standoffs. 

 

Here is me demonstrating the issue: 

 Note that in this video I am greatly exaggerating the amount of shock needed to make it freeze, only for the video. 

Here is what happens afterwards: This can go on anywhere from 20 seconds to 15 minutes. I actually gave up after I recorded this and am typing this on a Macbook haha.

The only two things I think may be causing this are either the PSU or the RAM.

Damn! Definitely wouldn't want the PSU to fry any of my other components. I'd really like some way to test and see if the PSU is truly the root cause. This one has a really good warranty though if it comes down to that..

Unfortunately I do not. Only thing I could think of would be to get my friend's out of his PC and try it.

The HDD would be sensitive to physical shock, you could try disconnecting it.

Then I thought "NH-D15"!

Don't drop your case that way with 2.91 lbs hanging off the MB!

About the heatsink: Yes, I know. It's actually new and the same thing will happen with my Corsair H80i AIO. I only dropped it like that so you guys could see it in the video better. It should be able to withstand that kind of abuse anyways

Update: since posting that video, my computer has not turned on since. It's still looping. I think it is completely dead at this juncture.

Update: I believe I have found the issue! It's the RAM. I'm not sure what needed to be done, but I moved my RAM around and it worked fine. They're now back in the same spot as before and working fine. Even tried bumping my case a bit and all is well. If the issue pops back up in the future, I'll probably proceed with an RMA through G.Skill. 

 

Probably just needed a re-seat!
