Mine seem to crash a lot
Motherboards make a HUGE difference. I only use higher end ones. The little extra is worth all the time and headaches saved.
Powersupply is another big thing.
You are right. The very big dissapointment for me is asrock h110 pro btc+.
I always stick with asus, but for one time I bought asrock. The mobo is not stable and they are not issued new bios since release...
