Why does the PIC slow down when I connect some current loads?

[Tricka90]

I'm making a PIC controlled LED lamp. I'm noticing that every LED I add to the circuit the PIC program slows down more. Why is it happening and how can I work around this problem?
I'm using a PIC 16F876 with 12MHz chrystal oscillator.
If you need more information I'll be happy to give them.

Yes. You need to zip and post the complete project files.

Hi it may be your perception and i don think there is any thing to deal with a controller... If it happens the most probable reason would be disturbance of crystal or oscillator in any means.........
