@Smunkey Hi Smunkey, did you leave the new RAM in, or did you take it out again and put the original RAM bsck? That's what I would do first. Does it BOOT then? If not make with the MediaCreationTool an USB Window Installer Stick. Win 10 is fine. ( for Win 11 replace Win 10) Boot form the USB Stick the F8 tab pressed (some PC you need to tab the F10 or the F7 tab). This will open the Bootmenu. Choose the USB stick to boot from. On the first installation pages there is in the left low corner the option Repairing. Click on this and you will enter Windows RE. Go into Extended Options and try to repair the Bootsequence. If this doesn't help, you can try to install a clean Windows with the same stick. Success, daddle
