Repeated BSOD and loud laptop fan issues

[computernativity]

I’ve been experiencing repeated BSODs on my laptop, which I initially thought was due to overheating. I repaired the heat issue, but the BSODs persisted. The technician suggested it might be a hard disk fault. If it is indeed the hard disk, can I replace it myself, and are there any settings I need to adjust afterward?

Also, despite cleaning all the dust, my laptop fan is still very loud.

Any advice would be appreciated!

Thanks!
