I traced my bluescreen issues to a faulty SDcard/USB reader.
After testing everything else and buying a new graphics card.
At work they managed to kill not 1, not 2, not 3 but 4 industrial PCs before they realised that a USB hub was causing a short circuit or something and frying the motherboards. Gj.
I have one of those little usb to serial things - sometimes that gives me random blue screens. This is why some cost £2 and some cost £20.
