System Video Signal/Post Issues

[dkd123]

Hey everyone, I'm new to the forums but been an LTT fan for a while.

 

I've had a system I built a couple years ago that keeps acting up. Any time I move it or take it apart, it either won't post on or I get no signal. I read on another forum the motherboard chipset and cpu aren't a great match, so I thought maybe getting a new mobo would fix it, but sadly it hasn't. When I assembled everything outside the case, I got no signal. Inside the case, it wouldn't post. I'm not getting any beeps from the speaker (I think it might be broken). Any tips would be appreciated. Thanks in advance everyone!

 

Specs:
Motherboard - ASUS ROG Crosshair V Formula (Previously MSI 970A-G43 Plus)

CPU - AMD FX-8350

CPU Cooler - NZXT Kraken X41

GPU - Sapphire R9 380 Nitro

RAM - G.Skill Ripjaws X Series 16GB (2x8GB) DDR3-1600

SSD - SanDisk SSD Plus 240 GB SATA (Boot Drive)

HDD1 - Seagate Barracuda 1TB 7200RPM

HDD2- Toshiba 5TB 7200RPM

PSU - EVGA SuperNOVA G3 750W

Case - NZXT Switch 810

 

What I've tried so far:

One RAM stick in each of the four slots

Resetting CMOS (usually fixes signal issue)

Unplugging everything from PSU except for CPU, Mobo, and GPU

Assembling outside of case

is the 24 pin motherboard power cable loose, that happened to me once kinda annoying.

No I checked it, it's fine.

Have you tried booting without the GPU?

No but if I did there are no video outputs on my mobo so that wouldn't fix the video signal issue.

 

I'll still try it to see if it stays on anyway. It'll have to wait till later since I'm posting from work lol.

So after spending most of the evening yesterday trying to figure out what was causing my post issue, I figured it out. It was actually my SATA SSD. I'm not sure why, but whenever I plug an SSD into my PSU using a SATA power plug, it won't post. If I use my cases hot swap port, it gets power from molex and adapts it to SATA and that works.

 

However, I'm still not getting any signal from my video card. Any thoughts?
