Weirdest ever bottleneck glitch

Hello,
Now I have repeated this in every post but I can't blame anyone as no one is stalking me, hopefully: I have upgraded from my Asus Radeon HD 7770 GHz edition to an EVGA GTX 970 SC ACX 2.0 and I thought as I have another older PC, I would put the radeon in it. I went ahead, oh by the way I also changed the PSU, and put the PSU and GPU in the other PC. that PC has a Core 2 Duo E4600 @ 2.4 Ghz and I knew it wold bottleneck that GPU but not in the way it actually did... You see, I had a GT 220 in there before and I worked fine but after I put the AMD in, HUGE areas in game became fluorescent green! The map in WOW, terrain textures in many games, weird artifact-like graphics but I haven't OC'ed that card. Have any of you seen this before? I thought of under-clocking the GPU to stop this but does this cause instability? Will it fix the problem?
Thanks for a quick answer :D

You're suffering from artifacts, could be the PSU though too much coincidence to start failing right after moving it to the older pc, could be an overheating issue or even a driver issue. Did you use DDU or Driver Cleaner to remove the Nvidia drivers before installing the AMD ones? if not it's very likely it's a driver issue.

Reinstall drivers using DDU:

download.html

If you've done that already and problem persists, it's time to verify the stability of the components...

Test the CPU with Prime95

Test the RAM with memtest86+

Test the GPU with furmark.

For both CPU and GPU tests monitor their temps and voltages with HWMonitor Pro or similar.

Hopefully with this...

Hopefully with this you'll find out what is exactly causing the issue.
