I've had nothing but trouble with the memory in my computer. Fails memtest if it runs it at all, Any memory fails, 1 gig sticks 512's doesn't matter, they all fail in my computer doing memtest86 V 1.65. Put the ram in my other computer, it passes with flying colors. My usb TV is out of sync, audio slowly lags until it is impossible to watch people talk, I guess I must lip read a little, If I shut off the tv and turn it back on it works for a few minutes until it starts to lag again, and it seems that I am watching Iron Chef. I've been on the support phone for about three weeks, daily trying to find out what is wrong, found it today, I have to turn off USB legacy support. What the heck does that have to do with my memory? I've been through a lot of grief with this, formatting weekly, reloading tons of programs, and I would sure be beholding to someone that could explain what the problem was. If this is posted in the wrong spot, I apologize, but I thought it was a Mobo problem.
