Static red light DRAM and CPU

I am having problems with my B550m riptide. After a failed ssd restore with easeus backup with winpe (got message like invalid file) pc did not boot anymore. In bios the ssd was recognized but the option to set boot device priority was gone. I change a setting in bios (I read a tip in a post, can?™t remember which setting :( but I remember it was a setting you have to enable with a intel arc card) pc wont boot. Got a static red light cpu and dram. Tried resetting the bios a dozen times using various methods but no luck. Changed videocard, psu, disconnected everything to bare minimum, tried both my ram single in all slots. Removed mobo from case, reinstalled cpu and cooler. I don?™t know what I can do anymore. Pc worked great for 6 months. Can someone please help me!?
