PC HDD light is red and it doesn't boot up.

[thisusernameisa1readytaken]

I recently installed an R9 380 in my computer a week or two ago, and a few times now I would turn on my PC and the HDD light would go red. I can hear the fan turn on for a second and the monitor turns on, too, but the bios or the windows startup won't, well, start up. I can still open and eject from the CD drive.
Last time this happened, I just jiggled around the wire connecting my hard drive to my motherboard to get my stupid PC to boot up (which is how I'm writing this). Now today it crashed twice while playing Dark Souls 3 (which works very well might I say) but booted up fine. A few hours later I come back and the light went back to red .
Before I had a 750ti and that worked fine, no crashing or dysfunctional boot ups. This all just started with the new GPU.

Any help would be appreciated .

Hi there thisusernameisa1readytaken,

Sorry that you are facing some issues with your WD drive. 🙁

As you've managed to boot up when trying to see if the wires are properly connected, then I believe all of this could be a connection related issue. Is the drive even spinning up? Is it recognized by BIOS?
My suggestion would be to attach the drive with different cables(both SATA and power ones) to another SATA port.

Let me know how this goes,

Whoops didnt mean to choose that as a solution. Stupid phone doesnt have a reply option.
Anyway, i switched out the cables and nada, the fans dont even turn on. The gpu doesnt light up, everything is dead except for the red light on the case and the optical drive.

Then I believe you need to troubleshoot your other components as well.
Try to take all the components that are not needed for the system to boot:
- Leave just a single RAM stick.
- Take the GPU out.

Double check all the connections and cables.
In case the issue persists, you can troubleshoot your PSU. The easiest way to do so is to just borrow one from somebody and try it on your system.

Ok so it was working for a little bit but the red light problem came back. I was trying to get it to work but it just didnt boot up, so instead i took out a ram stick and put in my old graphics card and it's working. What does that tell you?
