Question about Dell XPS 420 PC Desktop
Today, we were working on the electricity, and i flipped the breaker in my son's room and his computer will not go into windows mode, only a black screen....how do i get this to reboot?
Try clearing the motherboard state:
unplug power cable
hold power button 15 seconds
release power button
plug in power cable
start as usual
As much as these issues can be as drastic as noted above, this is rarely the case.
finnaly, please post some more info, do any lights come on?
The power light can be different colors and may blink, and there are diagnostic lights on the front (usually marked 1,2,3,4).

When it comes to power surges it's hard to say how much of the system was fried. It could stop at the power supply, it could stop at the motherboard, or it could go on to other components and fry everything.
The only way to tell what's good is to start testing individual parts in another machine. I don't recommend testing new parts in the damaged system as the new parts could be damaged by parts that are not working correctly in the old system. Also until you isolate the good parts you have no way of knowing if the part is not working because the motherboard is fried, or if it is because of another part that needs to work, for it all to work.
Although there is less of a chance, it is possible that testing damaged parts in another system can screw up that system as well.
If you don't have another computer to test on, you will need to take the system in to a repair shop and have them test the components.
Sorry for the bad news, but if it got past the power supply, chances are at the minimum, the motherboard is fried. There is also a good chance you will need a complete new system.
PS Always disconnect all electrical components when the power is being worked on. You should test all the TV's and stereos that came off that switch too..
