I built a computer 2 years ago, the one in my profile. I have upgraded the PSU to a 750W Ultra Lifetime series but other than that the stats are correct. I have been getting random bluescreen crashes since I built it but they are definitely coming much more frequently now. I backed it up a couple of months to a previous known good point and it's still crashing. I have tried to turn off the Mobo utilities and take it down to default settings just to insure the optimized settings weren't causing the crash. This is the second set of sticks of RAM in this thing and the second video card. I'm at a loss for ideas here on how to narrow down this problem to an adequate solution.
