It may be a hardware problem since I'm using new computer but I'll ask anyway. So it happens sometimes - system becomes unable to write anything on hdd, applications start to crash, I forced to reboot. I encountered it twice (and I suspect I will again), first after suspension to RAM and right now, out of the blue. Has anybody encountered similar problems? Or guessing what could be the cause?
