I've given up with my AMD 290 over the past week, its a reference card which has ran pretty poorly since launch tbh but the amount of throttling its doing now and the micro stutter is horrendous! I've tried cleaning out the PC and improving the airflow but it still hits 94 C after like 5 minutes of gameplay and starts throttling
The final nail in the coffin for me is now the AMD drivers have made Windows 10 blow up, at least that is the only conclusion I can come up with. I updated to the latest version of Windows 10 and it was fine for a few days then it wouldn't boot, it would start loading Windows then just hang (black screen with none responsive keyboard/mouse). I tried everything from booting into safe mode, reseating the card, repairing startup etc but noting worked. The only way I could get into Windows 10 was to run via the onboard Intel chip which works fine, so after uninstalling the AMD drivers and using DDU I tried again and nope... still hung on startup.
The card works fine in the BIOS and on my Windows 7 partition (with the latest AMD drivers) during gaming etc so I think the card is fine. So I tried to format to a fresh install of Windows 10 and nope... it installs fine then as soon as it tries to boot into Windows for the first time it hangs which I'm guessing is just after the point it has installed the drivers.
I went back to the Intel GPU and bam, worked a treat! So I tried my older AMD card and nope.. crashes on boot so I'm guessing it has to be something to do with the AMD drviers?! Windows 10 seems fine, the GPU seems fine in other OS's, so I can only think of the Windows 10 AMD drivers herp-a-derping? But even after removing them I haven't had much luck!
The only thing I can think that is left to try is to reinstall Windows 10 again with no network connection attached while running on the Intel GPU, then making sure that auto install of drivers is killed from Windows 10 and manually installing some old arse drivers.
I think that is something I'll wait till the weekend for as I want to play Overwatch dammit!
Has anyone experienced anything similar?
