Hi there,

I have an HP Pavilion desktop computer which I noted some noise coming out of the computer, I opened the casing and noted that the PSU had this "burn't" plastic smell, I have looked for any soot marks but there is none, Today I noted the smell is getting stronger but the computer is working well, what could be making the PSU smell like that, How can I make this smell go away? I just feel uncomfortable with this smell.

Desktops/laptops usually tend to get hot from overuse and one of the reasons you smell burning plastic is because of overheating. Check your desktop’s fan and hardware temperature. If the fan is not working properly or is damaged, don’t use your PC until it’s repaired, else you can end up with a burned motherboard and/ or the processor. Also, check your CPU fan of any dust built up, if there is a lot of accumulated dust, please clean it up with help of a soft brush gently and carefully and make sure it is dust free.
