I have a 2011 Dell Inspiron 570 when Windows 7 was doing updates the PC crashed and than I smelled smoke from the PC thinking it was the PSU but it wasn’t I tried a different PSU PC still doesn’t post it only has orange button I tried removing and putting back in the RAM still didn’t work and than I took apart the entire PC than tried doing it again still didn’t post I will have to get the exact same Motherboard from eBay
