I have a dell dimension 2100 on my bench that was working but running very slow and freezing up . I pulled the cover off and the processor was full of Dust. I took off the cooling fan and cooling fin and cleaned them and reinstalled them. now all it does when you press the start button is show the dell logo, on the screen the is no post or bios. it just sits there any ideas???

Is the processor seated in the socket good? How about thermal transfer between the processor and cooler...did you use new thermal paste?

I never removed the cpu but I didn't have any paste to put back on the cooler. would this cause it to not be able to get past the dell logo to the post??? I have done this before and never had to use new paste as I don't have any. I'll definitly get some though.

It doesn't take much to cause a bad connection in the CPU socket and would certainly cause your symptoms. Try removing the CPU and reseating it in the socket. Check your cableing, too. Make sure all the power connectors are firmly set in the motherboard.

Thermal transfer is also very important...the CPU can overheat quite quickly without proper cooling and will either shut the machine down or prevent it from starting. Always use a good thermal paste when installing or reinstalling a CPU cooler unit.

The inability of this machine to POST at all points to a bad connection or a bad processor, though.

I have checked & rechecked the connections, I pulled the cpu and checked it out and reseated it but still no luck, I have to go to town this afternoon and hopefully i can find some paste. (small town syndrome) and try that, otherwise you think it would have to be the cpu? how about the motherboard could that cause it? It seems funny that it would post one minute then nothing the next???

Yes, the motherboard could be the problem...but being that the only thing you really messed with was the CPU cooler, that's the area I'd be looking at first.
