keep getting many warnings through out computer session

[Evaristo A. Zapata Jr.]

I keep getting several warings again and again and here
they are-

1.)shsn.exe has encountered a problem and needs to close.
We are sorry for the inconveniance.( comes out every so
often and is a pain in the ..)

how do I take them off so they don't interupt burning and
internet surfing etc. Any help will be apreciated
Thanks , Evaristo
