Spent 6 hours troubleshooting a no boot because of a $2 thermal pad
Last Saturday I decided to swap out the old cooler on my Ryzen 2600. Cheap upgrade, just a $25 tower cooler from Amazon. Put it all together and the PC would turn on but no display at all. Fans spinning, lights on, but black screen. I spent the next 5 hours reseating RAM, clearing CMOS, swapping GPU's, basically everything you can think of. Finally I pulled the motherboard out again and noticed a tiny thermal pad from the old cooler's VRM heatsink had fallen off and was stuck behind the CPU socket, right on some pins. That tiny little pad cost me half a Saturday. Has anyone else wasted a whole day on something this small and dumb?
