I suspect the hard disk. Attach an external disk, and install system unto it. If this works, then you must replace your disk.

I installed new hard drive already. It did not resolve the issue. I tried old 80 Gb and new 500 Gb - its still freezing the same way.
However I will trying working from usb flash drive oly. This test will eliminate hard drive sata cable connection between hard drive and motherboard. Maybe its a cable.
What else can it be? I need ideas.

If freezing is the same with a new hard drive, but is OK with an external USB drive, then you can suspect the physical connection between the disk and motherboard. I do not see any other reason.

There’s one problem with running your MacBook with the battery removed. MacBooks and MacBook Pros automatically reduce the processor speed by about half when the battery is removed.
If you have a MacBook with the removable battery you can get a new third party battery fairly cheap on eBay.
Or for $129 from Apple http://store.apple.com/us/product/MA566LL/A?mco=MTY3ODQ5OTY

If you exclude a hardware issue, perhaps you have a software issue. Are all these freezing processes with the same system and with the same apps running in the background or are they different?

I got third party battery and still having same issue.
I reinsalled OS X several times. Tried booting from external USB SSD hard drive. Machine will start once and i leave it with battery in for few hours and it will freeze on the boot again.
There is no apps except the standart which came with OS X. Its a brand new install on external SSD which i connected to USB port. I tried booting from it on my friend's MacBook Air 1.86 Core 2 Duo and its fine.
I am thinking maybe 10.5.8 OS X is overloads machine. I will try 10.4.11 just for the test

Leopard definitely does not overload your 2 GB of RAM, there is something else.
