Long time lurker first time caller here, been building and fixing PCs as a hobby for about 30 year, yes Im old, and I was always the family IT guy to help out with the occasional virus, driver, or god forbid h/w failure. My 35 y/o sister who lives with my mother, and her and her husband sit in their rooms all day smoking weed and playing sims and runescape. She told me her C drive failed and computer is overheating. She brought it in and this thing literally has lung cancer. It is so caked with nicotine and weed penetrated dust and tar that the on board M2 SSD overheated and died and several case fans seized and the GPU fans were spinning so slow you could visible see the blades. I hit it with compressed air and then after it would not come off 99% ipa and air. It was like that scene in constantine where the devil pulled the lung cancer out of him. Picture does not do it justice but my hands were actually stained and have been sticky with tar and skunk weed today. Had to replace the SSD and power supply most of everything else I cleaned, or tried too.
