I open machines for a living. These are the notes I wish I had.

I’m Andrew. I build PCs and I fix the ones that already got “repaired” once. Laptops, towers, the usual consumer stuff. I’ve been at it more than ten years, mostly on other people’s machines after they already bought the wrong part.

This site is just that, written down. Dead laptops, swollen packs, disks that click, paste jobs that cooked the VRAM. I don’t do model teardowns unless I had that chassis in front of me. I write the tests I run first so you can follow along on whatever’s on your table.

If I link a tool, it’s because I would reach for it after the diagnosis. I’m also fine telling you not to buy anything yet.

Some links are Amazon Associate links. If you buy through them I may earn a commission. It doesn’t change the test order. The line Amazon wants is on every page: As an Amazon Associate I earn from qualifying purchases.. Full version on the affiliate disclosure page, and how I test if you care how a product gets in a guide.
