Well thats one of the biggies of screwing up a computer, either that our your just getting radnom error messages. If your truly are out of memory that quick you obviously used it on somthing. Computers just dont screw up ya know. lol Do you download a lot of music, games, etc. If so youve probably ran into a virus, trojan, etc. I dont look at porn either I just know that its one of the easiest ways to infect your computer.I got my computer screwed up because of song downloading. What type of virus anti hacker software you got anyway. Another simple way to sometimes fix a problem would be to system restore. You select that by going into the tools section under the start menu and putting it back to an earlier date. Let me know if that works as well.
