All of a sudden Im getting "page-fault -in- non-page -area" message along with aphysical memory dump.. i havnt added any software or hardware..any ideas why?

your memory....try running memtest and see if any errors in your memory ram.

It can also be caused by IRQ conflicts but the main cause is memory. Often caused by having different brands/types or RAM on your board. Minor differences in latency can cause it too.
A possible fix is to set your page file memory manually instead of letting Windows control it. The popular setting is 2X you RAM...
