|I wouldn't get to excited about the mini_dump as wont give you a lot of information to enable you to solve the problem. The best place to look for that in in the Event Viewer.|
The mini-dump is for sending to Microsoft for their programmers to look at and contains a dump of they system state at the time the error occurred, registry value, memory contents and the like. Unless you have access to information on the inner workings of Windows it wont make much sense to you.
IRQL_DRIVER_EQUAL_OR_LESS is often caused by a hardware error or sometime a corrupted drive. The error codes that came with the BSOD will give you far more information than the mini dump will.
