Just upgraded my old athlon t-bird 900mhz to a new mobo with an Athlon XP 1800+. Anyway this isn't the first time I've installed a new motherboard but I've had a problem this time. When I boot it i get no picture on my monitor. My video card is inserted properly and it was working fine before the upgrade. Any ideas? Did i fry my processor or something... (no idea how i could of done this)
