I have reseated the vid card/ram and tested ram individually to see if it is the trouble.. Both ram/vid card have now been tested in other PCs and function perfectly. When I power the PC on, everything spins up like it normally would, so there is definitely power going to it... I'm wondering if there is a connection on the mobo that is missing, I havent used this PC in ages and all looks okay, but I can't be entirely certain. Am in the process of looking up the pinout for all connections on the mobo. Anyone know what else I can do?
