Hello,
Next time you get a BSOD stop error, write down the Stop Error Code (like Stop 0x0000000A IRQL_Not_Less_or_equal), and any information mentioning a file or driver (like - the problem seems to be caused by the following file: tcpip.sys).
Also how you were using the computer and what program you were running when the Stop error occurred.
Post them and someone may be able to help you identify the hardware, or software cause.
