hey andre, I think I have the same problem as you with the overload of system resources when my download speed is too much. I followed your instructions and it came out to be the file NDIS.sys thats been screwing me over. However, I have no idea where to find a driver for this..with some research i found that my network controller is a nforce 500 sli but can't find any new drivers for it. Is this the correct thing I'm searching for or is it something else? Thanks for the help so far
