The first thing you need to do is download a program to overclock the video card with. Rivatuner will work and is what I use. When you open the program there should be two sliders: one for core and one for memory. You will overclock the card by simply moving these sliders, however, you should only overclock a small amount at a time.
You should start with overclocking the core. Just move the slider 5-10MHz and then test in 3D Mark. If you have overclocked the core too far you will see \"snow\" (a bunch of white dots on the screen). So, just continue doing this, testing each time for snow. Once you do see snow just back down 5MHz and recheck. Just try to get your max core clock speed without any snow or lock-ups.
Not that you ahve overclocked the core it is time for the memory. Before you even start you should return the core to its stock speed (record your max OC first). Then just repeat the steps you did for the core, but instead of snow you may see artifacts, which are disorted lines and shapes.
Now that you know the max overclock for both the core and memory you need to see if they work well together. So, just return the core back to its max overclock you got earlier and look 3D Mark plenty of times to see if you ecounter3 any lockups, snow, or artifacts. It may also be a really good idea to play a few games for a couple hours to see if anything abnormal happens. If you do run into problems just back down the core and memory a bit. Just keep doing this until it is completely stable.
If you want to overclock further you would need better cooling. The best air cooler is the Zalman VF-700 CU.
Overclocking should be taken slow so you do not damage anything. You should also do thorough stability testing. This thread covers that a bit. You can search google for even more information or ask questions here.
Its not entirely true that you cannot OC the FSB on an OEM machine such as a Dell. Depending on what clock gen IC the board has, you can use software such as softFSB to chose the IC from a list and OC it from there, therefore increasing the FSB speed, and hence the CPU.
Couldn't you just use the jumper/dip switches? From what I have seen most OEM boards have them. You could proberbly get that celeron to about 3.2GHZ :)
ooo... krazykaveman.. nice to see you joined :)
