Computer Doesn't Boot when GPU installed Red LED Lights on BOOT_DEVICE_LED Need Help ASAP

Alright I built this computer about 3 years ago and I've had a fair share of problems. Right now it doesn't seem to want to boot when I install my GPU. I came home one day and decided to clean my CPU for the first time in months. During this I decided to air clean my system with an air can. Upon cleaning the CPU and Cooler, I booted up the system and it worked fine. I turned it off because I wanted to redo my overclocks..

When I tried to boot into BIOS nothing worked. There was a red light on the VGA led. I've tried:
1. Resetting CMOS,
2. Unplugging the HD from the system, turning on then off, plugging it back in and turning it on

Then I tried taking out the GPU and only connecting my monitors to my on board graphics on my motherboard. That worked and that's how I'm currently typing this out. So I tried to:
1. Put the GPU in and use on board graphics (nothing popped up and red light on BOOT_DEVICE_LED)
2. Spamming F2 (while having the GPU connected and using on board graphics) would result in a distorted static-y black and white screen.

So please help ASAP I don't know what to do. I really don't want to replace to this card since it was definitely working before. I did nothing between the time I reset my system to fix my overclocks and turning it on. My GPU fans are turned on. I'm willing to provide whatever information you need to help assist my issue.
