I have a Dell Dimension 4550 desktop computer, Windows XP Home with SP-2 and
all Microsoft updates installed, 768MB of RAM. No viruses that I know about.
I run AVG anti-spyware, AdAware, SpybotS&D, CWShredder, Spyware Doctor, and
Zone Alarm (free version). I keep them updated daily or as often as the
companies release updates. I scan daily and so far, so good.
All this started about a week ago. I'm not sure what is causing all this,
but whenever I plug a USB flash drive into either of the two USB ports on the
front of my computer, or into the one USB port open on the back of my
computer, or if I put a CD or DVD in either of my optical drives, the
computer will respond with either of two error messages.
Here they are:
[first error message]
explorer.exe - Application Error
The instruction at "0x7c910f29" referenced memory at "0x00000000". The
memory could not be "read".
Click on OK to terminate the program
Click on CANCEL to debug the program
OK (button) CANCEL (button)
If I click on OK, the error message goes away, I'm back to my desktop, all
my desktop icons briefly disappear, then re-appear, and my computer seemingly
returns to normal. Except I still cannot use any USB port or optical drive.
If I click on CANCEL, I get another error message, which reads this way:
Error Signature
AppName: explorer.exe
AppVer: 6.0.2900.3156
ModName: ntdll.dll
ModVer: 5.1.2600.2180
OffSet: 00011e58
No button appear on this box. I have to use the Ctrl-Alt-Del to bring up
the Task Manager to box this box, then restart my computer. When the
computer restarts, I still cannot use any USB ports or optical drives.
I have run the built-in defragger and the error-checker. Both work normally
and the error-checker does not report any problems.
I thought I may have a bad or failed memory card, so I ran the Microsoft
Windows Memory Diagnostic (http://oca.microsoft.com/en/windiag.asp). I ran
it overnight and it came back with "no errors".
Here is the second error message:
Windows Explorer
Windows Explorer has encountered a problem and needs to close. We are sorry
for the inconvenience.
If you were in the middle of something, the information you were working on
might be lost.
For more information about this error, click here.
DEBUG (button) CLOSE (button)
If I click on the CLOSE button, I'm back to the desktop and the disappearing
and re-appearing icons. If I click on the DEBUG button, I get a box with the
same information as you can read above (AppName, AppVer, etc), except at the
bottom of this box is this:
To view technical information about the error report, click here.
CLOSE (button)
When I click there, I get a larger box full of random numbers and letters.
When I close that box, if I wait for a moment or two, I get THIS box:
DrWatson Postmortem Debugger
DrWatson Postmortem Debugger has encountered a problem and needs to close.
We are sorry for the inconvenience.
DEBUG (button) CLOSE (button)
The CLOSE button takes me back to the desktop. The DEBUG button shows me
another error signature box, which looks like this:
Error Signature
Event Type: BEX
P1: drwatson32.exe
P2: 5.1.2600.0
P3: 3b7d84a2
P4: dbghelp.dll
P5: 5.1.2600.2180
P6: 4110969a
P7: 0001295d
P8: c0000409
P9: 00000000
You folks can imagine how long it took me to write all this down while
reading it from my screen!
I thank you for reading all this, and would be grateful for any and all
advice which would lead to resolving this problem.
Thank you.
