Occurred immediately after inserting a USB key. 2 days later a pop up window displays and Says " USB device not recognized by windows. Re insert device. If windows still does not recognize discard USB device. I did reinsert 3 days later and windows displays drive contents. I deleted all System restore points so system restore not available.1 person needs an answerI do too

Often caused when win believes there is a network drive or other external drive.Try updating your chipset driver from either the PC makers makers site, or motherboard site if a generic PC

Updated chip set (Flashed BIOS ) and same problem.

Have you checked event logs, checked the behavior in safe mode, or with a clean boot, or with a different user account?

In safe mode "My Computer" loaded very quickly as it should. I then disabled all start up items in MSCONFIG and rebooted. "My Computer " again took 2 minutes to load. I am the only user on this computer.The event viewer shows that each time I invoke "My Computer" the event ID 7034 occurs with properties : The Windows Image Acquisition (WIA) service terminated unexpectedly. I disbled WIA service in MSCONFIG and guess what? "My Computer" now loads fast.Problem is with WIA service. Can this be repaired?

While in services.msc what is the service set to? Automatic, Manual,Disabled?In the meantime, go to Start/Run/Regedit, navigate to this key and setaccordingly:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\stisvc"Start"=dword:00000004See if that helps

You could create a new user account to test the issue, but it seems that that is not necessary since you have isolated the behavior to the Windows Image Acquisition service.Are there any entries in the event log that indicate further details about the unexpected termination?(Looking for some kind of exception code such as 0xc0000005 of 0xc00000fd.)

Since the service is disabled, the Start value's data would be set to 4. Disabling the service would be a workaround.

There are no exception codes. I am a little nervous with registry edits so I am just going to leave the WIA service disabled. All my scans are done on a different computer. Thanks for pointing me in the right direction. Problem solved (almost) for now.

OK. One other thing you could check would be to run drwtsn32.exe from start->run. Then check the Crash Dump setting, and find that file. See if the time stamp matches or is close to the last unexpected termination of the WIA service - if so, please indicate as much.
