Describe your issue:
System boots OK, Windows login screen appears, password entered and before desktop is displayed you see 1-2 seconds of "white noise" fuzz like an old TV with no signal. Desktop then appears, and machine functions normally. Games play OK, no issues at all.
Additional question, the memory speed of my 5700XT is "locked" at 875Mhz. Ive seen that this is intended on high refresh rate monitors but mine is only 60Hz, is that another issue i have or is it meant to be like this for high resolution as well as high refresh?
