hey everyone. im some what confused atm as i have never encountered a problem like this. i just installed a new graphics card(asus 3870) and after installing cat8.4 my computer will not shutdown...it just hangs at the shutting down screen? its not frozen because the little circle is still moving or whatever it is any thoughts as to why this might happen? i can manually turn it off with power button but the reset button does not work. oh i made sure i completely removed my old drivers before installing the new ones.
