I bought my computer nearly four years ago, and it has been remarkably stable and well-running. However, recently I have been getting the dreaded blue screen of death with the following messaqge:

Filename: VMM(01)+0000BDC0
Error: 0E:0028:C000CDC0.

I have no idea what this means, but apparently it has got something to do with the file "Tpwtray", because when I press Enter and return to Windows, I am greeted by the message that this file is causing an error in the "Kernel32.dll".

Pressing Enter at this point is hopeless, because it only results in the "'Tpwtray' caused an error in 'Kernel32.dll'"-message being reiterated ad inf.

Does anybody know why this occurs and what can be done to help it? By the way, I have done an antivirus test as well as scandisk, defragmentation and a test for spy-/adware, but alas to no avail.

"Tpwrtray.exe" has to do with power managment/control of mobile toshiba computers. It's provided by toshiba, not windows.

Might start your research on that venue. If it can be installed/updated again, might be worth trying.

Also, try updating your motherboard chipset drivers. If they're at the latest update, try re-installing them. If this started after an update of this driver. Back down one update.

Might update other drivers as well. Video, sound, modem, ect.

When does this error usually happen? Any certain activity, or just random.

You didn't just do a Windows Update did you?

Thanks for the replies.

I haven't done any Windows updates recently. I have now reinstalled the Tpwrtray.exe (Toshiba power management) and other Toshiba system programs, and then I'll see if the problem continues.

I believe the problem to be related to a problem which I have always had, namely that memory is not freed up when a program is shut down. Having done some research on this back when I first noticed it, I have concluded that this is a problem with Windows Millennium. I use Rambooster to remedy this problem, although that works only partially.

The reason I believe these problems to be connected is that I have started using the "Dr. Watson"-program again, and last time the blue screen occured, Dr. Watson reported that the program which initiated the error, in that case Acrobat Reader, was trying to access memory (unfortunately I have deleted the exact message). When this occured, I was only running Acr. Reader (from within IE), so there really should be no resource problem.

You could be right since you know your own system but in my experience vmm (01) errors are almost always due to something new which you are using which requires you to update your chipset drivers.

Have a look at the homepage link on this response, point 15.
