I am going from an old intel 965 chipset to Gigabyte p45. The CPU will be a quad core instead of dual core I have right now. I have been reading mixed reviews about reinstalling the OS (I have Windows 7 Ultimate 64 bit). I don't want to reinstall everything.

So, has anyone had any problems with upgrading their mobo and CPU and not reinstalling Win 7? It seems like it should be able to handle the upgrade, correct?

Also, if you did this successfully, what process did you follow? Do I just plug my hard drive into the new motherboard and I am ready to go?

Thank you

If you're putting a new mother board in, you will HAVE to reinstall windows. If it's just the CPU you will not.

While I don't recommend it, you can try it and see what happens. It will likely ask you to re-activate, and you will have to install all of the new drivers, and it'll be a big fragmented mess on your hard drive.

But you might also end up with nothing but problems. I mean, this could end up being much more trouble than simply formatting and starting over.

But I'm curious about one thing: do you have an OEM Product Key, or Retail?

That's not true.


Going from an Intel 965 to an Intel P45 might be ok. The issues tend to occur if you switch company chipsets (i.e. NVIDIA -> Intel). However, the only way to know it to try.

You will need to reactivate though.

To answer most of your questions: (1) a fridge cannot cool a PC (2) 64-bit OS for over 3.4GB (3) If a PCIe card fits, it should work (4) Resolution, not screen size (5) Report, not respond to Spam (6) Single-Rail/Non-Modular PSUs are not always better than Multi-Rail/Modular (7) Sequential does not matter as much as random for OS drives (8) Requirements come before hardware for servers

And this is why I said that it can be attempted, but I don't recommend it as it could prove to be a big frustrating headache.

I know... Smykster said you have to... but you don't.

So far, I haven't heard about people having problems with Windows 7, so I wanted to see if anyone has actually run into issues when they didn't do the reinstall.

People absolutely have Windows issues if they try to switch mobo chipsets from one brand to another.
