So i'm having computer issues, which i thought were usual memory problems, namely that after booting, the computer restarts (sometimes in seconds, sometimes it takes minutes). I've tried searching which of the RAMs were faulty. I'm using 4x2Gb RAMs, on an ASUS z77 Pro3 motherboard. I've tried all the RAMs in different positions, until i got to the current setup, having the cards in two slots (B channel), after which i've tried Memtest, it passed for 4 times. Also worked for like two days, now the issue is the same. What could be the cause of this? Should i continue trying switching the RAMs around, or is the motherboard faulty, or maybe something else? Thanks for the help.
