I have a desktop system running Vista X64. This error first came up in Jan & I wound up taking the system to a local computer shop. Now 3 months later the same error loading OS message is appearing @ boot. I've searched the web, and have checked to see if my BIOS has the correct settings. I don't want to take my PC to the shop every 3 months. Has anyone else experienced these problems and could suggest a solution... The error is on boot get "ERROR LOADING OS"
