My son bought an AMD A10 based desktop 5 months ago and has been using the on-board graphics driving two monitors since then - no problems. To increase his gaming he got a Corsair 600W power supply and an MSI R9 280 for Christmas. He was very impressed with performance - for a few days - but problems now arising.
Firsly, one of the monitors inexplicably goes monochrome. I cannot find out why, CCC appears to be all defaults, so no switch to put it back. I have found that only doing a system restore gets colour back - for a time. We have changed cables, monitors, and display ports without eliminating the problem.
The second issue is that the main display (usually with the second, monochrome, monitor turned off) starts to jitter, with the task bar dancing up and down.
I suspect that one of the new elements either power supply or the GPU is the problem and should be returned - but which? Or is there something I can do without returning anything?
