Tried it. Same result. Of course there's no System Tray in Safe Mode so I couldn't click on the USB icon to effect a safe shutdown.

Here's an interesting oddity. Following that experiment and while operating in normal mode I inserted a thumb drive. First I got the small window asking how I wanted to view the photos on it and I clicked "Cancel." I then right clicked Start > Explore and got the same sort of shut-down. Couldn't repeat this behavior.

The suggested workaround yields the same crash with OR WITHOUT a file transfer. The crash happens upon physical removal of the thumb drive from the computer.

lets try a linux live cd...that will tell us if its a hardware issue or a operating system problem...
the following instructions are for recovering data from a system that won't boot but in this case we only want to see if the computer crashes when you remove the flash drive...
get puppy linux 2.16.1-seamonkey-fulldrivers.iso here...

Clicking on the link you provided for Puppy Linux results in a File Not Found message with a "redirect" with links to Puppy 4.3.1. Can that distro be used in the same way? How about Ubuntu? I already have that although I'm not sure I recall how to find the drives because I haven't fooled around with it for a long time.

The last part of your directions seem to be directed toward recovering files from a non-functional computer. That's not my case. Just wacky USB behavior.

I sure appreciate your persistence.

I think we've turned a corner here.

I booted into Ubuntu, inserted a thumb drive and read a couple of files. Then I clicked on "eject" for the thumb drive before disconnecting it physically from the computer. NO CRASH! I went through this process again but this time omitted the "eject" before disconnecting and again there was no crash.

I will check and make sure the link in my puppy canned is updated so it works...
since we now know its got to be a windows problem since linux doesn't crash when removing the flash drive...
we need to first try sfc /scannow and if it fails to work we would have repair your OS..

Ran sfc /scannow twice per instructions at http://pcsupport.abo...sfc-scannow.htm. No errors reported. Rebooted.

Crashes continue.

Still crashes with another User Account.

Don't see any reference to ACPI in my BIOS listing. Under the Power Management heading there are three settings: Suspend Mode (S3 is selected), AC Power Recovery (Off), and Low Power Mode (Disabled).

look around in the bios for a setting that decides what controls plug and play...
if its set for the bios to control ...the switch to the OS...if its set to the OS switch to the bios...
we just want to toggle it..save your settings and reboot...
if that doesn't help...I am running out of ideas short of a clean install...
before we opt for a reinstall of the OS...let me run this by a few other techs to see if they have any thoughts..

happyrock,

BIOS Dell Computer Corp.Version A06, 10/08/2003: no reference to Plug n Play. Here's the listing:

System Time
System Date
Drive Configuration
Hard-Disk Drive Sequence
Boot Sequence
Memory Information
CPU Information
Integrated Devices (LehadySelect Options)
Power Management
System Security
Keyboard NumLock
Report Keyboard Errors
Auto Power On
Fast Boot
Os Install Mode
IDE Hard Drive Acoustics Mode
System Event Log
Asset Tag

I've checked the options under each of these where provided and none of them is ACPI or Plug and Play related.

Would a screenshot of the Belarc Advisor readout be useful to you?

Is it likely that this problem could be cause by the interference of a startup program? I've got lots of them but can't identify a large part of them.

JSntgRvr,

Thanks for jumping in the pool here. Perhaps another island resident like me (Oahu) can crack this nut.

Simple question before we begin - is Norton Anti-Virus a script blocker?
