I have a dual monitor setup and it's worked perfectly since the start. However, ever since a required update a couple weeks back (don't know the exact version number) my secondary screen starts blacking out every second or so whenever I have a game set to fullscreen.
My Radeon software version was 17.4.4 (still indicates that in the system tab) and tried to update to 17.5.2. Didn't work (Radeon froze during the restart step, and has been doing so ever since) but the updates tab says I have 17.5.2.
In the mean time, the problem's been getting worse and worse, the blackouts starting earlier to the point they now instantly start the second I open a game in fullscreen. Tabbing out seems to make it exponentially worse.
Everything is about as stock as it gets, not overclocking or anything, and I have been unable to find anyone with a similar problem.
Long story short: PLEASE HALP!
