Problem with all courses for this stuff is that you need to pay beaucoup money for it, usually because they are designed as seminars to train corporate IT groups and not meant for specific individuals. It's not completely out of reach price-wise, but it's something that'll need saving up for. Here's a couple seminars:

Remember that interpreting BSODS means interpreting Windows internals, which means understanding OS design, basic programming language like with ASM and C, driver development and reverse engineering. Courses/material that covers any of those will be very useful. You're studying on a composite of skills, not just specifically BSODs - interpreting BSODs is not a skill in itself, it is a reflection of already existing skills.
