Looking for someone with the proper equipment and experience to reflow a GPU. I've got a card that sometimes won't post. I don't know it's history, but I'm assuming ex-mining. When it does post, it'll loop benches for 12 hrs without a problem. Other times it won't post at all (booting with onboard, doesn't show up in device manager at all). Thorough cleaning with isopropyl, new paste and pads and a BIOS flash didn't remedy it, so assuming it's hardware related. Hopefully someone who has the knowledge and tools to look the board over, test individual components, and reflow the board safely (versus the oven trick). Anyone on here? Or anyone know someone?
