Question random BlueScreenOfDeath(BSOD) while gaming

[MrPeace]

Well... last summer i bought a gaming pc and it was working fine but then after 1 month multiple BSODs started happening and it sarted while i was playing RE2 with the error "driver_irql_not_less_or_equal" multiple time til the computer stop booting... well i unpleged everything and send it to a guy to fix it, when he booted the pc nothing happened... he told to return home and after a day he'll tell me the results and he told me that there was nothing happening to my pc... so i came back with the pc and it was fine... this summer, recently bluescreen returned and it accured once with the same error so i created a system restore and i seeking for help... i dnt want these BSOD to occur again cause i dnt have any information of them
SORRY IF THIS IS LONG
