built a fresh PC, everything was good until i downloaded csgo. i usually play on stretched mode but for some reason i get black bars on either side. running win10 sapphire r9 390. i was searching around, apparenlty i had to use ddu to uninstall the new drivers and install an older one which supported my problem (many other people did this as well) so im pre sure i did it correctly, now when i start up my pc i see the gigabyte screen where i can press f8/f12 etc, then after i proceed to a black screen. sometimes i get further onto my desktop screen, then blacks out again. connected with a hdmi, also noticed gpu fans spin sometimes and dont spin some other times. pls help
