Could my PSU be causing artifacts.

I bought a new PC and when I first plugged it in and went to the BIOS screen there were loads of tiny pink lines across the screen. At first I didn't think that it would mean much and that they would go away if I installed the graphics card drivers. But when I installed the drivers they didn't go away and my main monitor that I had connected with display port wouldn't go in any res except 800x600 and the lines hadn't gone away. So I checked in task manager and it gave me an error message and saying that windows had stopped the device from working and code 43. And after a while of googling the problem and trying to get it to work I decided that it wouldn't but to check if the GPU was actually the problem I put it in a really old system and it seemed to work fine with no artifacts. The system that I tried it in had a rm850 watt PSU and lower end components and my new PC has a CX750 watt so I wondered if it was a power issue.
Thank you for any advise.

I think it's possible.
I would run HWInfo and check the voltages.
They should be within 5% of +12, +5 and +3.3.

I tried using that program but for some reason all the values on the gpu are blank

Hmmm....that might be pointing to the GPU. I think the GPU should show up.
Did you at least see the voltages? They are usually up top. Sometimes they aren't all there.

No it has information like what gpu it is and what driver it’s on but not clock speed or volts or anything but I has that for my cpu and ram etc

I think that info should be there.
I'm thinking it might still be the gpu even though it works in the other system.
