my UX31 made some random hard freeze in the last weeks. I tried to run memtest86 (from grub) and it always freeze or throw memory errors after 5-10 mins. Probably it's just an overheating problem while the memtest86 is running but it doesn't seem like that.
Is it normal? Could you run a memtest on your UX31 without getting error or freeze?
I'm gona be greatfull if someone would try it too.
