I bought this computer in February. It worked like a champ till October then there was no display on the monitor. I changed monitors and cables but still no display. Computer seems to be working fine. I'm not sure what the warranty is. The video card in on the motherboard. I found a refurbished mother board for $20 and it's on the way. If that doesn't fix it then I'll throw it in the dumpster. I have always avoided Dell from the stories I've heard but I thought for this price, how bad could it be. Now I know.
