I just fried my processor a couple nights ago (nice burn marks on it too) it took the motherboard with it. Now I've replaced my mother board and processor and my computer still won't post.
I've gone through the trial and error of trying my internal video instead of my agp video card and switching out my 2 ram chips.
My last idea is that it could be my power source. But it seems to be still working and powering all my fans and cd/hd.
Even with it sending power to my fans ect could it still be the cause of my computer not booting even to post.
p.s. the power source is a bit old (2-3yrs I think) and I had to use a 20->24 pin adapter on it for it to work with the new mother board.
