Hello, I built my machine about a year ago. Off and on for the last year, I get random Blue screens. The problem is very inconsistent, but it persists. I could get a blue screen 3 times in one day and then not again for a week. It happens at random times, during games, clicking around web pages, reading email, it doesn't seem to be triggered by any particular action. Also games that I play crash very frequently. I play games such as Bad Company 2 and Just Cause 2. It seems laggy and then it just freezes. I can ctr+alt+delete out, choose task manager and then I can see that it says the game has stopped responding. Another thing I have noticed, which I am not sure if it matters or not. Out of my 6gb of memory, eventually 3+GB of it will move to "Cached" in the task manager. I'm thinking this is because it's being used for all of my other programs and reserved there. I end up having pretty low Free memory, even after closing all of the programs. Could this be causing games to freeze? I have not had a lot of time to work on the problem as I run my own business and am on it pretty much all of the time. I have reinstalled my video card drivers and in the past have even taken the CPU off to reapply thermal paste, thinking that maybe it was overheating, but to no avail.
