I had problems with Asus in the past too - it’s their motherboards that are wonky. When I tried to get help with the problem (constant hard crashes that caused rebooting), I discovered they had no technical support at all, not a single person employed to assist - and that the warranty amazingly didn’t cover it as every motherboard of that model had the same issue. The issue was to do with how the graphics adapter was handled and I ended up having to use some dodgy third party BIOS written by an enthusiast to stop it from crashing.
Absolutely ****ing unacceptable, IMHO. Will never touch an Asus product again.
