Question about upgrading to a better CPU…

When you put a different CPU in your computer, this doesn’t require that you reinstall windows again does it? You just put in in and update the BIOS if needed and you’re set, right?
Answer #1
Well you would need to upgrade the BIOS prior to installing the chip but otherwise correct.
Answer #2
Depends on what your going to do, what cpu with what motherboard.
Answer #3
you would need to upgrade the BIOS
Depends on the BIOS version and if updates (if any) were needed to support newer processors.
reinstall
Nah – the drivers are mostly related to the motherboard – not the cpu. The first boot of the system will be extremely slow; reloading windows from scratch is definitely faster and leaves you with a cleaner installation.
Windows will definitely need to be re-activated.
Answer #4
If your running windows 8 you can just pop it in and boot normally as long as you don’t do something like swap a x64 bit cpu for an x86 one.

I just did an upgrade on an old PC, from a Celeron to a P4.
Windows 7 stopped during bootup and sorted out it’s files.
Then it all booted up OK.!
Answer #6
I’ve upgraded CPU’s on xp, vista, and 7 systems without any problems; but have had to update BIOS as you said.
Answer #7
So things that you installed for the system using the old CPU, like the motherboard drivers, chipset, northbridge etc., those aren’t related to the CPU characteristics at all? They won’t need to be reinstalled after you swap the CPU’s?
Well you would need to upgrade the BIOS prior to installing the chip but otherwise correct.
Really? What would happen if you did it afterwards?
Answer #8
^If it boots and lets you into Windows without BSOD you have no problems, however if a newer BIOS is required for your new CPU you will need access to another computer to download the newer BIOS and apply it to a USB stick in order to flash the new BIOS if your motherboard allows it. Another potential issue could be your RAM settings if its set at a speed your motherboard doesn’t support (unless you have set it to run at a higher speed it should be at a default of 1333mhz or 1600mhz, so it should be OK), also if your system is overclocked you will need to set the BIOS to default so it can automatically detect the correct voltage for the new CPU.

I see. And this?
