Charles asks:

Can I switch from 32bit processor to 64bit processor?

Hi, Charles.  If I’m reading your question correctly, you’re asking if you can change the processor in your PC from a 32-bit processor to a 64-bit processor, and not switch back and forth between the two processors, right?  The reason that I ask is because, as far as I know, there’s no way to install two processors on a PC at once.  That would require having two motherboards.

The short answer is that it depends on your motherboard.  An older motherboard can’t physically have a 64 bit processor installed on it.

The longer answer is this.  If your motherboard can handle a 64 bit processor, then yes, you can switch out your old processor for a new one, as long as the processor is compatible with the motherboard. You CAN do this yourself, but if you haven’t had some experience at changing items out on a motherboard, I would recommend leaving this to the pros.  The following goes for desktops.  For laptops, the motherboard and processor are typically proprietary to the computer, so you’ll just have to buy a new laptop.  Actually, even for a desktop, it may be less money and trouble in the long run to just invest in a new computer so that all of the parts are designed to work together.  Also, before you attempt this, make sure that you’ve backed up your old PC and have a copy of Windows on hand, you may have to reinstall.

If you want to do it yourself, here’s how you do it:

1) Completely disconnect your computer from external power.  I know that this seems like a “no-brainer”, but I have met some no-brainers – so there you go.

2) One side of your computer case should open easily, this is usually the side with the fan.  Open it.

3) Unplug the CPU fan from any connectors and very carefully unscrew it from the motherboard.

4) Remove the CPU fan and open your CPU clasps.  This is usually a clip that you just have to open.

5) Gently remove the old processor.  These are held in place partially with a special compound called “thermal paste”.  Your new processor should have come with a tube.  If it didn’t, buy some.  You need it.  The thermal putty on the old processor may have dried, in which case you just lift the old processor out.  If it hasn’t, you will have to gently work the processor loose.

6) Put a generous amount of thermal putty on the underside (the blank side) of your new processor, and fit it in place.

7) Reverse the above steps to close your CPU clasps, reinstall your fan and put your machine back together.

Voila!  If the computer gods have blessed you, you now have a working 64-bit machine.

I cannot stress enough, however, how easy it is to mess your machine up, so it’s always best to leave these things to the pros or buy a new machine.

Hope this helps.
