Error message upon booting computer

When I boot my (old but still functional)HP Pavilion a700n desktop I get an error message that gives the option to send\dont send. When I click on the button for more information I get the following two lines.

C:DOCUME~1\HP_Owner\LOCALS~1Temp\WERba76.dir00\MXTask.exe.mdmp

C:DOCUME~1\HP_Owner\LOCALS~1Temp\WERba76.dir00\appcomat.txt

Can anyone help me with this and what is it?

Thanks
