Hi all. First time caller, longtime listener.

I just built my first new computer in quite a while. For about 15 minutes it seemed to work great, then suddenly the screen flashed black and when the desktop came back it was covered with a pixelated tie dye of colors. It didn't freeze, just became covered with this overlay of garish colors.

That happened before I'd had a chance to install the drivers. Since then I've installed them, reinstalled them, reinstalled windows and reseated the card. The problem remains.

I went out and bought another Visiontek rx480, but it has the same problem. I tried An old Radeon HD 4850and it performs fine.

System specs are:
Windows 10 Pro
Ryzen 1700
Asus Prime B350M-A
Crucial 16gb DDR4 2400 Ram
Crucial 525gb MX300 SATA SSD
Seasonic 520 WATT fanless PS.
Visiontek Radeon RX 480 8gb

Any ideas?

Thanks for the suggestion, but since I get the same problem with two different RX 480s, I doubt that it is a defect in the card itself.

starting to guess the psu might be faulty (?) no matter how good a psu are there could still be lemons there
try your gpu on someone's pc to test it before jumping to that conclusion though

are you sure you dont have application like msi-ab in the background ?, sometimes msi's default settings are higher than the stock clock speed, i would try downlocking the card see if the problem persist, or bring it to a local pc shop/distributor to test the card there

Very possible. It was sold as an "overclocked edition" unfortunately the problem makes the screen almost illegible, so it is very hard to check anything or alter any settings. At this point I've given up, returned it, and bought a GTX 1050 Ti, which worked without any issues.

It looks like there's something wrong with the drivers. I have no problems running my system in High Sierra or Ubuntu but when I use Windows 10 Pro, I get the exact same problem. I can recreate it immediately if I put my system to sleep in windows. My Visiontek Radeon 480 8gb works fine on my Intel system but goes nuts on my Ryzen rig,
