Hello,

I am from Romania and i'm not as good at spelling english as speaking...
The Memory_Management blue screen error that you have is a RAM problem.
I had this proplem and it ocoured often but I fixed it with a simple solutin: well ia have 3 banks of RAM on my notherboard and 2 Ram modules (2x512mb) so placed one module in the firs bank and the seond module of Ram in the third bank, leaving the middle bank empty. I never saw the blue screen again.

If you have the same situation , do what I did.
If you have only one module and at least two banks, try switching it's place.
If you have the same no. of modules and banks, try switching betwen then.

If none of this works try exchangeing Ram with a friend. If the problem continues your motherboard is not compatibile with the RAM or it has a defect.

Hope it works ...
