MP 1,1-5,1 Mac Pro repeated chimes on startup

[Gothboy1]

Lately sometimes(not always) I get the regular chime and then repeated softer chimes and grey screen upon startup forcing me to hit the power button to restart until it boots. Sometimes 2 times sometimes 3 times. Shouldn't be related to RAM.....any thoughts?
I've already read this: https://support.apple.com/en-us/HT202768 but it doesn't fit into any of those scenarios.

I assume you’re talking about your cMP 3,1.
Have you tried removing ram and then reinstalling one at a time?
Have you changed the PRAM battery in the last 5 years?
Have you tried reseating any PCIe devices? Same for any external devices (USB, FireWire etc).

Yes That's right!

Yes did that.

Have you changed the PRAM battery in the last 5 years?

Yes the other day in lieu of the situation.

Have you tried reseating any PCIe devices? Same for any external devices (USB, FireWire etc).

Will try reseating no external devices plugged in right now.

I experienced that before...turned out to be a bad Radeon HD 5770. So perhaps your GPU is failing. Do you have another one you could test with?

On a 2012 cMP this was a symptom of a failed 5770. As @fhturner suggests, perhaps another gpu may resolve this.

If you end up needed another 5770 card, I have a couple spares I can sell that I removed from my 2012 5,1 a year ago and replaced with bigger cards.

If I had a HD 5770 kicking around, I'd give it away for free , since the value is very low.

Supposing the GPU is failing , you could also look for an alternative that performs much better e.g. GTX 680 (and flash it).

Well if you want I would be happy to take it as I’m still having startup/boot issues. That would be appreciated!
The current is a Radeon 2600 as shown below and it was installed 5 years ago. At present the MP is again down after crashing after I typed com in the right side finder. It starts up but won’t boot stays in grey screen.

Thank you it's not the GPU.
