Hi Huwawa,

Sorry for the delay with the answer. Does this problem occur on the specific configuration or on any Core 2 Duo PC? Do 
you experience this problem on Core i3/i5/i7 CPU? To get a suggestion and then a solution for you we should reproduce 
the problem. Please describe a simple way to reproduce it.

I guess this behavior may be an effect of SMM. If so you can decrease this effect by disabling all unused HW and options
 in your BIOS setup.

Respectfully,
Oleg
