My pic doesn't want to run from 3V. It works fine with 5V. Can anyone tell me what's the problem?

picasm will become famous soon enough

You need the LF version to work on 3V and even then it may require a higher voltage when using a higher clock frequency.

Check the data sheet for the PIC chip that you are using, it shows graphs and tables of it's power requirements.

That depends on frequency. Most non-LF PICs are specified to run at 2 volts at the frequencies achievable by their internal oscillators.

Also, check you don't have Brown Out Reset turned on in the config.
