Well I tried the monitor with my other pc and it had no issue , also a swapped the gpu for another one and the problem went away.

This likely rules out the monitor, but does not yet rule out the PC power supply.

After inspecting the gpu I did notice that it had a LM317 voltage regulator on it in a TO92 package , I could try swapping it from the other duplicate card with bad ram and see if that fixes it.

It's worth a shot. Also, when you are swapping parts, you might also try whether swapping C13 and/or C31 (the two electrolytic caps near the LM317) helps with that problem.

Cheers , i'll keep that in mind.
