HP DV& RAM Upgrade

On second thoughts, why mess around with my machine with a beta.

Is it possible to re-install win7 premium 64bit OS over my existing 32bit OS. Is there any compatibility issues that i need to be worried about. 

Also, what is the basic difference between these two bits OS.

Sorry, if i sound naive but that's what i am...new at this.

There is actually some chatter about that right now as to whether Win8 is going to be able to be dual-booted. Something about a protected boot environment. I just installed it on a spare laptop and was able to create a dual boot with Kubuntu Linux but not sure it will dual boot with Windows 7. My best advice is to reinstall Windows 7 as a 64 bit installation....that requires a clean install, not an upgrade. Most Windows 7 install disks give the option of a 32 or 64 bit installation and the same Key Code will work for either, I believe. So you can use the existing Key Code to install 64 bit, assuming your laptop came with Win7 installed. I think the same is true for Vista, too.

The difference between 32 bit and 64 bit is basically the width of the data highway. 32 bit is a 2-lane road and 64 bit is a superhighway. 64 bit is more stable and in my opinion runs a bit faster. The big thing is it can address an almost unlimited amount of memory. With memory so cheap right now it just makes sense to install a lot.

Ok, understood about the dual boot. 

Yes, my machine came with a factory installed Win 7 premium 32bit. So as you suggest, i should be able to do a clean install of win 7 premium or profession 64bit. 

Now, what is the basic difference between a 32 bit os and a 64bit os....why this two types....???? I know almost all asian models are 32bit while the US models are 64bit. 

My wifes notebook is from Best buy USa and it has a 64 bit win 7 premium, however, i fail to see the difference.

It is nothing you can see. They look identical. It is the way it is coded down deep to take advantage of the wider data lane for a 64 bit processor, as almost all processors on computers today are 64 bit processors, other than tablets and netbooks.
