Computer Total Power Loss

PlzDontKillDave · August 29, 2017

My computer is about 5 years old my first computer I have built myself.

Motherboard: Asus Z77 Sabertooth

CPU: 3770K I7 Intel

GPUs: GeForce GTX 980TI (main runs main screen) and 7970HD (secondary runs 2 screens)

Ram: 16GB of ram - CML16GX3M4A1600C9

PSU: less than 4 months old 1000W Gold series RM1000i Corsair

OS SSD: 256GB Cruical

Storage Drive: 2 TB WD Green

Game Drive: 1 TB Samsung SSD 850 EVO

My computer has been shutting down on me my screen go straight to black screens and my fans in the computer goes out as well. After about 4 seconds POST is fine and then everything boots back up. Lights and all comes back on. My thought was the voltage of the PSU, but it new. SO I went into my bios to see the measured values and they look fine. While playing with the settings to change it back from manual overclocking to auto my screen went dead and so did my fan led in my case. 4 seconds later it comes back as if i pressed the power button.

I think i narrowed it down to something with the wires.

I say this because out of frustration while the computer was booting up. I let my hand free fall on to the case and... BOOM it went dead. SO my thought was... hmmm while doing the POST i'll just bang on it hard... and sure enough it went dead upon me striking it. I did this a few more times and the results were the same. UNTIL that is the last time tried it. It wont shut down no matter how hard (to my liking... i could do it wayyyy harder) i hit the frame. When i get the time. I will take it apart and re wire everything. Take everything out clean it. AND finally gives me a reason to change out the CPU Heatsink... I have a Thermaltake SpiralQ on it. It does the trick beautifully... but it has a slight vibration.

Do you guys think there are other issues with this?

What other test do you think i should perform?
