Replaced CMOS battery, now system is dead!
Help!
I replaced the CMOS battery in my Dell Dimension XPS T500. Now, when I turn the machine on, the Dell logo comes up on the screen, and that's it. No hard drive activity. Nothing moving on screen. Hitting keys, , , doesn't seem to do anything.
I tried moving the jumper on the motherboard to clear NVRAM, but the same thing happens with the jumper in both positions.
How can I get this machine to boot again?
(By the way, don't ask me why I replaced the CMOS battery. I just looked at it and said to myself, "Hey, that's a real old battery in there! Why not change it just to keep things running smoothly?" Not very smart on my part.)

If the machine still fails to boot then strip the motherboard down to the bare minimum. By bare minimum I mean remove all expansion cards, disconnect all drives and leave just the processor, memory and graphics card in the machine after reseating them. If the computer boots this way then start connecting each device one at a time until the no boot scenario returns. This would then indicate which device has failed and is causing the problem. Also try booting the system without the keyboard, mouse or any other device plugged into the rear of the system. A faulty USB device has been known to cause problems. If you have more than one memory module installed then try booting with only one and then swap them around and try again. If you only have one memory module then try booting without any memory modules installed. Also try swapping the graphics card for another one. If this procedure doesn't resolve the problem then you maybe looking at a situation where the motherboard or processor has failed.
