I'm having trouble with a completely fresh Vista 64 installation on a box running MSI P6N SLI Platinum, Western Digital Raptor 74GB sata drive for the OS, 4GB Corsair Dominator memory and an Intel Core2 Duo E6600 (@2.4). The performance is absolutely terrible. Switching between apps can take anything from 10 to 60 seconds, and the disk appears to be swapping like crazy. Also when I pull up the task manager, even the taskmngr.exe consumes 50-60% CPU, and the total utilization is constantly 100%. I've installed the newest NVIDIA nForce drivers, all updates from Windows Update, and I'm feeling pretty fresh out of options.

Just to be sure, I ordered a new 500W PSU (my previous one was 400W), and some hard drive cooling, but I seriously doubt that this will improve anything.

Any clues? I would really like to get this thing working, though I'm sure XP64 would perform very well under the same circumstances.

Hi, do you have this latest installed: http://www.nvidia.com/object/nforce_...a64_15.00.html (if they provide any intel drivers for anything, get updated version from intel site)

Have you enabled all dma-related stuff? device manager/disk drives/your hard drive model/properties/policies/ various optimize & enable settings......

Tried disabling nforce firewall? http://www.nvidia.com/object/LO_28249.html

and as well latest bios? http://global.msi.com.tw/index.php?f...1&prod_no=1140

Notice i didn't have you go for drivers to msi site(in previous reply)...trying to get the very latest...they usually run like so, from most recent to oldest:

Intel
nVidia
MSI

PS Nvidia recommends, IF you also have an nVidia graphics card, to first uninstall graphics drivers completely BEFORE installing mobo updates, then afterwards reinstalling video drivers.

Vista 64(all win 64's actually-- esp. when using the newest hardware...bet you if you run Ubuntu 64bit you don't have those problems) is basically still in beta...here's some more info: http://forums.nvidia.com/lofiversion...hp?t28473.html
