I have gotten the colored snow on a few of my GPUs over the years, the issue hasn't
been brand or even vendor specific (AMD/Nvidia both) but it does almost always only
happen when I am using a DVI cable, never with HDMI or DP. I'm not saying it can't
happen with other outputs but it never has for me. I think it has something to do
with how DVI-D works with signal detection etc. If you are on DVI, try HDMI or DP.
I am no expert but I have assumed for a while now that the issue has something
to do with the way DVI wakes from inactivity. It also happens to me (when using DVI)
when I have the system connected to the same power outlet as the AC in my office.
Every once in a while when the AC inverter kicks on the screen goes black for a moment
then the snow appears. Switching to a different power outlet resolved that issue though.

DVI cable



HDMI cable



DP (Displayport) cable


The DVI cable is an older standard and the only cable type I have experienced the
snow you described with.

or try a different DVI cable .. not all cables are created equal. If your monitor doesn't support HDMI or DP .. then you can get an HDMI to DVI or DP to DVI cable to run out of the HDMI or DP port in the back of your video card to your monitor
