dmp file and blue screen error Windows 7

Hi,

Just wondering if someone can tell me how to read the dmp file created after the blue screen appears ?

I have just recently upgraded my Toshiba P300 from Vista 64 bit to Windows 7 Home Prem 64 bit. 

I dont know why Windows 7 keeps crashing and so far I have no idea of how to open the .dmp
file (I have zipped the dmp file and attahced below).
