Overclocking whats left

So I have this old Acer Aspire 4530 that I bought probably in 2006. It's been through a lot, all the peripherals are broken, and it's basically a slab of tech wired in to a bunch of things, positioned on an upturned shelf (the back (where the exhaust is) is angled upwards with an airflow under the computer... pretty much forming a right triangle with on angle being around 10 degrees high).

So basically, it's non-mobile laptop, that's far outlived it's warranty, and I am too poor to buy anything to upgrade it. Then I heard about overclocking, and I have been trying to do it for the last few days with no success. Turns out, I have a locked BIOS and a motherboard that confuses every overclocking program I have downloaded.

I've checked the forum for nothing really useful, and before you say how OCing a laptop is useless, it's really not much of a laptop anymore. If I need more cooling, I could take apart the case and stick the motherboard near a fan (at least that's what I have planned) because its immobile anyways.

(Off topic)
I was also thinking I could just take everything out of the laptop and stick it in one of the 5 computer cases I have laying around, using redneck tools like duct tape and maybe a saw for the disk drive (I mean cut into the case, not the drive itself). If anyone has any tips for doing this, let me know.

ADD Version: My computer is old, broken, immobile, I'm too poor to buy anything for it, and I want to overclock it but the BIOS is locked and no software I've found has worked. Help?

No help then?

Putting a fan near it won't cool it off that well?
Even if the case is taken apart, exposing the internal parts?

Like I said, the laptop is immobile, so I can pretty much do whatever I want to it (like adding bulky things to it, or making it take more space to air out the parts better).


If I had any cash, I would buy a desktop, but my budget doesn't really allow me to do more then save about $40-$80 a month. I could wait half a year and buy a decent desktop, but I'd rather take the quick route and overclock whats left of my laptop, so my games don't slow down as much.

Is there a way to do it with this BIOS locked computer?

Hm, so taking it apart won't really do much then, I guess I could find a way to build more heat sinks or a water cooling system if I need too. Assuming I get it overclocked in the first place.

I have no clue on writing a BIOS, but I could probably learn fast how to do it, if I need to.

The games I play on this machine (with little lag on lower settings, not lowest) are Fallout 3, Fallout New Vegas, Team Fortress 2, Minecraft, Half-Life (all 2 + expansions), and Portal.
The settings normally have medium textures, no, or full shadowing, no HDR or bloom, and at the most 2x anti-analyzing, and the game will run pretty smoothly, except when a lot of models/scripts then usual are running.
