Brand New Gigabyte R9 390 Random black screening and flickering

[desktopzero]

As I type this, the screen is flickering a bit, and sometimes just turns black for a couple seconds. The card is a brand new Gigabyte G1 Gaming R9 390, PSU is Corsair RM1000. Motherboard is ASUS Sabertooth P67, CPU is i7-3770. I have made sure all power cables are plugged in correctly. Output is via DisplayPort to a 28inch 4k Acer monitor. Does anyone know what exactly is going on? Any help would be greatly appreciated, thanks

Try to clear cmos, disable virtu, uninstall old drivers / reinstall.
By any chance you have overclocked your monitor? restore monitor settings to the default. Are you using an adapter to power the card? By any chance you actually run 400W PSU and? :F
I would suspect a driver problem.

i had same problems as you with r7360x after changing to windows 8.1 i got rid of the problems i had one or two crashes in a few Days but its much better.

doesn't seem to be an OS issue however. this is hardware or drivers.

for me it was os combined with drivers no doubt i was 99 percent sure it was hardware but installed win 8 and card is working good now

i believe, that your troubles were solved because you had to clean install drivers after you reinstalled your OS. it doesn't make sense that windows 7 would have problems which could be solved by windows 8.1

i did Clean install with windows 7 to i even tried it on two differrent drives but it didnt help i was ready to ship this back but tried win 8 and it worked right away i agree that it dont make sense maybe tdr delay works in a different way on windows 8 because i was crashing in 2d mode on win 7 when i managed to get a game or Movie going it didnt crash it was opening a browser and simple stuff that crashed it was like the driver didnt get loaded properly after boot
