[PC] - Memory issues

[Tiago]

How is your memory at mother board? 4+4+4? Are they all of the same speed and brand?
try to remove one and see if it freezes again, repeat the process and try to isolate the bad one (if it is a memory problem...)

I won't open anything, don't have the patience for that, and I'm 99% sure this is software related, as it happens only sometimes, like once a month or so, if it would be a hardware problem, it obviously wouldn't go away at all.
