Hi. I am running Windows 7 x64 and I have a problem where the computer lags every few seconds. For example, while I am typing this message, every couple words, the line cursor freezes, and then after a second, everything I type appears on screen.
Another example would be switching tabs in Firefox, clicking a tab, it would take a few seconds to switch. Going to a different program would have the same effect.
I ran MemTest for about 14 hours or so and passed. I have 8GB of RAM.
Does anyone know why this is happening?
