OK just after typing my last post I remembered I had a spare battery. So I installed it.
I still have no video output DVI or DSUB connector.
Now it sounds like windows not loading as I cant hear startup music anymore.
I dont have a speaker to plug into the mainboard, maybe I should get one to hear if there are any beeps. Otherwise I dont think its posting anymore.
It sounds like the mainboard is stuffed to me so I might just leave it at that and save some pennys for a new one.
