Overclocking an old CPU

[collector97]

I have an Intel Pentium 4 540 3.20 GHz Prescott.
775 LGA Socket

And 2560MB RAM Memory

There are 3 sticks of RAM:

Slot one: 1024MB DDR2 PC2-6400 (400MHz)
Slot Two: 1024MB DDR2 PC2-4300 (266MHz)
Slot Three: (empty)
Slot Four: 512MB DDR2 PC2-4300 (266MHz)

I've decided to buy a new PC but I still want to keep this one and overclock the CPU to get better FPS in games (the other PC is work only).

I never OCd a CPU but I've read that this CPU is the king of overclocking so that's gotta be good

OH... Almost forgot about the Motherboard
(don't know what's important so i'll just write all the info )

FUJITSU SIEMENS

BIOS:
Brand: FUJITSU SIEMENS // Phoenix Technologies Ltd.

you really cant OC with a stock cooler, i suggest you get an aftermarket one

something cheap like like CM evo 212

Do not invest any money into this PC.
It is soooo old even if you overclock the CPU to 4 GHZ it still wouldn't make a difference.
The reason for that is because the CPU is based on an old and painfully slow archetecture and also because since you didn't mention your graphics card, i assume you're using one that's intergrated.
And even if you're not the Pentium still won't cut it.

Either scrap this build or use it for work. It will not play new games no matter how much you overclock it.

I don't think you know what you're talking about...
I have an ATI RADEON HD 6450 1GB GDDR3 and i run new games like Mass Effect 3 and skyrim at 40-60 fps. Even battlefield 3 runs at about 30 fps.
That is until I got a new motherboard and a new power supply. Every game started lagging...A LOT. So what do you guys think is it the motherboard or perhaps my new Power Supply. (I can stll play old games like GTA III and VC with 60 FPS but mass effect 2 and 3 (witch had 60 fps both) now have 5 FPS!!!)
