basically it was flash player and silverlight also uncheck global video in CCC, also uninstall windows media apps like calendar video photos whatever that comes with the bundle, usually has some kind of affect with the drivers.
I have the Sapphire R9 290 Vapor-X OC and I love it.
Make sure when you get it to press the fan button and the on switch in the back there's 2 buttons total before installing the card that must be on. Install latest driver of CCC and install MSI Afterburner for OC features and rivatuner will...
Set the GPU clock settings in CCC to 990 MHz and leave High performance memory clock settings to 1150 MHz.
Only turn up the fan to 65% if running a game.
Leave power control settings to 0% and your games will play perfectly with out freezing.
The OC edition on these cards are garbage but run...
