I seem to have an issue with Aero in Windows. And I think this might stem from the fact that I overclock often and on an AMD processor. What happens is when the system is under stress or when the processor is clocked ALL the way down, the Aero Live Preview seems to not work. And when I hover the mouse over on one of the taskbar icons and move it away, it acts like the mouse pointer is still hovering over it when it's not.
I think overclocking might had damaged the memory controller on the processor since that's the only thing I can think of hardware wise, unless I need to change the default BIOS settings to other settings to tweak things...
I have the latest graphics updates. All the latest Windows updates except for two .NET 4 updates that won't install for some reason. RAM should be all ok, but I may need to check for sure.
Also, I've seen this happen on a laptop when I stress tested it for a day and here and there, it would do the same thing as my system. That makes me think of voltage errors since this also happens when I clock down considerably on my processor.
What do you think?
