Did you get the latest bios and drivers for this new mobo?
Asrock pro 4 seems to have a few models.
GTX 750 ti problem
Im guessing it maybe broke but this is my issue
I upgraded my pc to.. Asrock pro 4 Ryzen 5 1600x Ddr4 ram (cant remember the brand) Running my old evga gtx 750 ti.
Never had any issue before.
Problem happened first when running overwatch.
I got the lost render device crash. I roll back the drivers to the ones released in april and its runs ok.
I have no problems running guildwars 2 on near max settings. But hearthstone lags ALOT.
I check maintenance in windows control panel and i have HARDWARE ERROR alot. Since rolling back the drivers it seems to be stable. I played 20 mins of overwatch with no problem.
Is this a sign to change GFX card or is there something else causing the issue?
EDIT Just to mention my old system i was running a athlon 4x 860k and some micro mobo and had nooooo issues at all albeit i had to run it on lowest settings.
My temps are fine. No higher than 60degrees Windows 10 home fresh installion on ssd
