here are pc specs.

80 gig hardrive.

2.6 ghz pentium 4 ,800 fsb

NVIDIA GeForce FX 5200 video card

theres one fan on my power suplpy and one on cpu and on video card and on back of the tower.

my pc temperature can vary between 22 to 40.

depends what i do.and was celcius..

and if it is going to over clocked does it need more fan..i treid once to over clock to 3 ghz but the screen went funny ,so i put it back,

please tell me about this and over clocking.....

Just raise the fsb a bit at a time until "funny" things start to happen. You may end up at say, 2.8Ghz (or higher or lower), then run something like Prime 95 to see if the system is stable.

Don't make huge jumps all at once.

Chances are your heatsink and fan are up to the job and your temps are pretty normal.

There's a slew of overclocking info on this forum and all over the internet. You need to read some of it and understand what you're doing before you start.
