Typically, BSODs have a message number such as 0x000000AB which is preceded by the keyword STOP... Please inform the number... It also has a message such as PAGE_FAULT_IN_NONPAGED_AREA - inform us this also...
Also, inform if this bsod occurs during specific operations (opening a program, etc), randomly (even when doing nothing) or during bootup (inform at what stage of booting this error occurs, and if you are able to go to Safe mode and/or Last known good configuration)
