PC no longer boots. Breadboarded it as a result and get one POST Beep, would appreciate any advice

Hey there! First of all, thank you sincerely for taking the time out of your day to read into my computer issue. Here I will lay out my Computer's Specs (definitely feel free to point out if I miss anything that you feel is pertinent to the problem.)

Processor: Intel Core i7 920 / 2.66 GHz
Motherboard: Came from an old Dell XPS 9000, I believe the model is RI0707
RAM: 6, 2GB 2Rx8 PC3 - 10600U Kingston Sticks
GPU: EVGA GeForce GTX 980 Kingpin ACX 2.0
PSU: PC Power & Cooling Silencer Mk II 950 Watt
HDD: Western Digital WD1001FAES 1TB 7200 RPM SATA hard drive
OS: Windows 10
Monitor(s): 1 - Dell ST2410 2 - Dell 2000FP
Case: CoolerMaster Storm Trooper

Alright, so I started receiving some intermittent issues a few days back. I would be using the computer and my Monitors would go black and then come back as if the display driver had crashed. So naturally I updated my Nvidia's drivers but still I would get these crashes more and more frequently. I reseated the graphics card, replaced my monitor cables (and tried different inputs, DVI, HDMI, MiniDisplay etc.) but the problem persisted.

Then after another crash, my computer entered sleep mode and was only awoken after I reseated all of the RAM and cleared my CMOS via Jumper (also took the battery out for roughly 10 minutes.) Typing on the Keyboard or using the mouse yielded no results in the waking process. I was able to run the computer for around 1 hour before it entered sleep mode again in the midst of me using it (I have my power options set to never sleep) and I was incapable of waking it up once more. Trying what I did last time unfortunately did not yield any results.

Now when I began starting my computer, I would get a single POST Beep that I had originally just assumed was the post successful beep that I had grown accustomed to since it sounds so similar, however I would receive no display on either of my monitors on any of their inputs. As such I could not see if I was reaching the POST screen or anything. Leaving my computer running for several minutes I would continue to receive this POST Beep which made me believe that it was something more.

Recalling a guide I had once read on your wonderful forums, I decided to breadboard my setup to see if it would help narrow down the issue. I got the Motherboard set up on an old cardboard box, plugged in 1 stick of RAM, re-plugged in the CPU Power and connected the CPU fan to the appropriate pins and ensured they were seated properly. I Plugged in the 20+4 power from PSU and tried starting it up. I received the 6 POST beeps that indicate that no GPU was detected so I thought that was a good start. After plugging in my Graphics card and ensuring that it had all of it's 8 and 6 pin power connections seated well I would essentially get the result that was happening earlier. One POST Beep that would repeat every couple minutes without display to my monitors.

I remember reading that one POST Beep could mean BIOS ROM Failure. If that is indeed what is occurring, should I then attempt to flash my BIOS? If so, is there any manner in which I can do so without having video output? I've recorded video of one of my boot attempts (poor quality since it's from my phone) in the hopes that I would be able to share with you the POST Beeps it is making and perhaps you would be able to see something that I am overlooking.

I've since tried starting it with and without the CMOS battery in, with and without the HDD connected and USB connections. I have also tried starting it without the reset cord attached to it's pin on the Mobo since somewhere on the forums I remembered reading that a computer might constantly restart if the reset connection was shorted. I have not tried shorting the power pins to turn it on, I've just been using the connections that come from the case and running them to my currently breadboarded set up. I might be able to borrow a friends Graphics Card and try booting with that once he is around just to see if it's possibly a GPU issue.
Sorry for the wall of text, just wanted to ensure I was thorough. To be honest I'm not sure if I narrowed it down at all for you guys but I would be very thankful for any advice on further troubleshooting steps or possible solutions. Thanks again!

Thank you for the reply Calvin! Replacing CMOS didn't even cross my mind, I'll run down town here to pick one up shortly and update with the results. Would be a cheap, quick and easy fix, here's to hoping it does the trick

Hey there Calvin, I ended up replacing the CMOS battery with another CR2032 3V. Unfortunately, it yielded the same result. Any other ideas on what I might be able to try? Thanks again!

Dang, it had a good run at least, got roughly 6 years out of it. You're probably right though, I'll see if I can snag a replacement here in the next week or so and hopefully it'll be up and running again. Who knows, maybe it's time to upgrade the motherboard/processor since they are probably pretty dated nowadays haha.

Honestly, thank you for taking the time to help me look into this, I really really appreciate it. I hope you have a great day and a wonderful week!
