Hi newcomer and welcome to the Tom's hardware forum.

Ur question isn't very clear for me.

If u want install a 32 bit OS in a laptop that comes with x64 bits from the manufacturer, yeah, u can do it without problems. But be sure that u have a back up of all your files.

Yes it is a bit unclear what you want to do.
Asuming you mean that you are currently running a 64 bit version of Vista or XP, then yes you can install Windows 7 32 bit, but it will have to be a clean install, an inplace upgrade is not possible in this instance.
If however you are refering to the laptop being 64 bit capable, that is different alltogether and could have a 32 bit OS installed on it.
You will need to clarify if you need more help.

You really have a 32 bit CPU in that laptop, with some 64 bit extensions (for memory utilization and a few other bits...). So if you don't need or plan to use more than ~3.2 GB RAM, no worries. (Unless you have a sparc, PPC, or Itanium RISC chip, then you will need the appropriate OS for that processor...)

Oh please - not that old wive's tale again! The x64 is a true 64-bit processor. That argument has been done to death.

What a load of old croc, most cpu's from the last few years starting from when the Athlon 64 appeared are x64 chips.

As for the o/s, I would always go for x64 version, will run fine on 2GB of ram and allow you to do a painfree memory upgrade in the future without reinstalling.
