so my pc was shutting down everytime after i turned it on which made me think: "there is probadly some dust in the fans" well i opened it and everything seemed fine except my cpu cooler so i removed it and cleaned it carefully and then putting it back. now there are two problems first it randomly turns on properly but then shuts down without warning ( so there is dust in the gpu fan too and i fon't have the proper equipment to clean it up) secondly when it does not open properly i get a BSOD like this (while it looks like the problem is not in the fans since i can't say which one of them is shutting down first) 0x0000009C (0x0000000000000004, 0xFFFF8800226DB60, 0,00000000BA06
