Just thought I'd ask here in case anybody has had this happen before. My computer will just randomly use 98% RAM and lock up. Twice it happened watching YouTube videos and once playing rF2 so I know it's not software specific. I'm unable to really have a good look at Task Manager since the computer locks up with so much RAM being used. Does anybody have any ideas as to what this could be? I've done the malware and other security scans. Thanks.
