Help with dell dimension. 1100

[jay1992]

I have a Dell Dimension 1100 desktop computer that quit working a while back. I figured out it was a processor chip but I haven't been able to get another one til now. The original that was in it was a Intel Pentium 4 socket 478. The one I got from my cousin is an Intel Celeron socket 478. I put it in and tried turning the computer on but nothing will come up on the on the monitor, and none of the 4 LED lights on the back I/O panel will light up. On the front there are 2 lights. One is solid orange and one is solid green. Before the computer quit working they both were green. The light on the motherboard is also solid green which I was told meant the motherboard is still good. The fan still runs and the CD drive still turns on and opens. I can feel the hard drive running as well. I tried different memory sticks and that didn't solve the problem. Any ideas?

You actually have a slot 478 processor. You may want to try a different power supply, most likely if it did the same thing with old processor in itn then the old cpu still may be good.

Yes it's a 478, sorry about that. The power supply is still good because I had it in another tower about a week ago and it worked just fine. I know that the 4 LED power lights on the back should light up but none of them don't. and there are 2 lights on the front of the case that should light up both green. One is I believe the hard drive light and the other is a power light if I remember correctly. The power light is solid orange. When I have a hard drive plugged in the hard drive light is green. Nothing will show up on the monitor either. Seems like it would be something simple. About a month ago it would show up on the monitor but it always kept restarting itself and I was told it was a processor issue...
