Dissapearing Files and shortcuts in Windows 7

Hello everyone .. new to these forums. I'm running Windows 7 Ultimate 64bit edition on home built system with quad core phenom AMD and 8GB og meme using onboard raid 0. from installtion to running application s and installing printers this experience has been enjoyable. I really like the new itteration of windows.

With that said .. there seems to be a strange ghost in the machine here, first I had about 30% of teh icons on my desktop disapear from view (as seen in several other posts and forums on the internet this is not a case fo teh newbs where I turned off icons)... the icons just disapeared both from view and from my desktop folder. I accepted this may be a bug in teh RTM release and was reserved to wait for an update. However I thought I would post this because it is something new but has the same characteristics. I plugged in a WD 250GB usb drive I use for transferring files... several of the directories were showing no files in them and the drive free space was reported incorrectly. when I took the same drive over to my Vista 64 machine everything appears fine . reconnected it again to my Windows 7 machine and same results files were missing and the size was being reported incorrectly.

I was just wondering if anyone else has seen this behavior and would possibly have a resolution for it. Thank you in advance.

Sounds like - chipset driver. Which chipset driver or update are you using?

it's an nvidia based board... I upgraded chipset drivers through windows update. See Attachments for version infor for both the PCI and system management controllers.
