Choose Vista 64bit as the OS selection to download the chipset drivers. http://support.asus.com/download/download.aspx?modelname=M2N-VM%20DVI&SLanguage=en-us If found this on the Nvidia site, not sure it is the chipset driver though. http://www.nvidia.com/object/nforce_vista64_15.23.html . Tried those (updating chipset drivers) and I think it helped, but still getting high USBport.sys in DPC and Interrupts CPU usage. Still freezing up at regular intervals.
omenofthephoenix replied to MagicAndre1981's topic in Windows Tips 'n' TweaksHi everyone, I have spikes in CPU usage at fairly regular intervals when streaming video or playing a game full-screen. I have done as MagicAndre has suggested and done a trace and found the USBport.sys is most likely the problem. You mentioned updating chipset drivers, I think I did that but not sure if I did it correctly, I don't really understand the chipset thing. Tried updating USB drivers, nVidia chipset? drivers and BIOS but still having problems. Anyone able to help? Let me know if there's any info you might need.
