your processor speed is set by two variables, a multiplier and a system bus speed. The multiplier in a Celeron 700 is set at 10.5x, and you cannot change it, even if the motherboard offers other settings. The bus speed for that processor is 66MHz, and 10.5 x 66 is giving you a 700MHz clock.
The only way to overclock with that processor, then, is to raise the bus speed. Third-party and a few OEM boards will have intermediate speeds such as 75 and 83MHz, but on you Packard-Bell board, I doubt it. However your board MAY have a 100MHz setting, and if you are lucky the processor might just run at 10.5 x 100 = 1050MHz (1.05GHz).
However 1GHz is about the limit of the Coppermine PIII and Celeron processors. IF it works, you will most likely have to invest in a better heatsink than whatever Packard-Bell provided. That will be a $20-30 investment, check places like Step-Thermodynamics, CoolerGuys, and 3dfxCool for heatsink and heatsink compound options. A ThermalTake Golden Orb or Volcano II would probably work for you IF there is room to mount it. Remember, apply a small amount of heatsink compound to the top of the processor die, THEN mount the heatsink.
Another obstacle that you could run into is that Packard-Bell may have used low-grade memory that runs fine at 66MHz bus, but will become flaky at 100MHz. You can try removing one of the DIMMs and looking, if you see a "-10" somewhere on the part number it is PC66; numbers beginning with 8, 7, or 6 are PC-100 or better.
Now, is your VGA connector, where your monitor plugs into the computer, attached directly to the system board, or is it on a separate card that plugs into an AGP (brown expansion slot connector about four inches long), or PCI (white expansion slot connector about the same size)?
If it is on the motherboard then you have integrated graphics, and those are probably dragging your performance down more than the processor is. If it is a separate card, then what does the card say? (i.e., if there is a square, bare chip, in the center of the card, what is written on that chip, or if not, then is there a model number or anything silk-screened on the card?)
