I have a problem, after i recently bought a brand new mother board and graphics card my pc has been going a bit strange, for instance when i put the side hatch of the pc back on after doing something ie. tidying up wires, it takes o while longer for the bios to post but when it does and it boots up into windows i cant get into my computer(the folder)it just takes ages showing that torch thing shineing on the folder but when it does find it a generally have a harddrive missing! could this be a heating problem or something hardware wise? ps if i dont get this fixed my mum wont be too happy!
