AMD Phenom X4 9350e (2Ghz)
PNY Nvidia 9600GT
Windows 7 64bit
ECS 780GM-A m-bo
After I boot up the box, if I play video or play games, everything runs smooth.
After 10-15 minutes of this, (either idle or play back), whole system becomes jerky.
Moving windows, etc is all jerky(choppy).
I do not see any processes taking up a lot of CPU, CPU is idling at 7-15 % usage.
Got latest Nvidia driver
installed, latest mobo firmware installed.
Cool & Quiet disabled.
CPU-Z reporting full speed.
Even playing Spider solitare, I can see the graphics are not smooth.
What could be the issue?
