Printing Problems related to .NET Framework?

Archived from groups: microsoft.public.windowsxp.print_fax (More info?)

My DOS programs are printing truncated reports, which
look like gibberish.

When I turn the computer on I get this error message:
Microsoft.NET Framework
"An unhandled exception has occurred in your application.
If you check Continue the application will ignore this
error and attempt to continue. If you click Quit, the
program will be terminated."

This started happening after I tried this morning to add
a 256MB PC2700 memory module from Centon. I have a Dell
Dimension 2400 Desktop with 128MB of RAM.
The computer started beeping and the diagnosis was that
the memory was incompatible or had problems, even thoug
Centon, in their website said this was the right memory
upgrade.

Are these problems related? Why am I having problems
printing in DOS?

Any help would be appreciated. Thanks
