BSOD error – irql_not_less_or_equal

My PC has gone through several errors which I assume I managed to fix but I don't exactly know what is causing the problem right now. I would be really glad if someone could tell me what the problem is being caused by. Link below is for the dump file. Thank you in advance for anybody who offers some advice/insight.
