PharmingInStyle Because that's the next step if a reboot doesn't work? Sort of like what a foreign tech support person would say.

Ensavier From what I understand this was a bigger problem a while ago than it is now, and even then seemed only really a problem for RAID related changes. Usually windows 10 at least, maybe 8.1/7 as well, will detect that the drivers you have aren't the right ones and will try to load a generic "microsoft" driver and/or search for a better one it has access to. There can be some conflicts that still pop up with some devices on a mobo change. For instance, when I popped out a ASUS something I forget for a X399 MEG Creation my Sound Blaster Z drivers were causing a blue screen when I didn't reinstall for some reason. Fixing it was as easy as a safe mode boot and getting rid of them but I was getting a new NVME so I reinstalled anyway and just backed up with ACRONIS.

If there aren't errors effecting you then you're probably safe. The real killer is if there is a potential error chilling in the background that you don't notice and then when you plug something new in, it can become a real PITA to track down. I don't know if that's really a thing you have to worry about anymore.

Pawelr98 With Win7 I actually jumped from Gigabyte 870A-USB3(AMD 870) to Asus Crosshair IV Formula (AMD 890FX) and then to Asrock X99 Extreme 4.

All without reinstall.
After booting I just cleared older drivers and installed new ones.

So basically running the same installation since December 2013.
A fresh install I made when I purchased my first SSD I use to this day(840EVO 120GB).

This. You should analyze carefully the event manager, check all driver versions (get intel chipset ones from intel), then u can rule out a fresh install.

Long ago I had no issues with motherboard upgrade prior to p67 and w7. I can assume that this still hold true with z170 and above & w10 YMMV.

JedixJarf Well back in the day it was driver and pch related, now though with win 10 it's much less of an issue.

The Pook 4690K to 6400/6700 to 9900K on one install and was fine for me, ended up being a benchmark for HWBOT that "broke" my install and I decided to reinstall.

I'm getting random hangs (they're so infrequent it's hard to figure out what it's from) occasionally where I never used to so technically it's running worse

after a few months of swapping out what spare components i had, psu, cpu, ram and gpu i swapped the mobo back and then after a week upgraded to W10. that was a good 8-9 months ago and haven't really felt the need to clean install in UEFI mode. my rig runs 24/7 so boot shutdown is not a concern for me.

i feel so dirty.
Windows 8.1 and 10 are not prone to loose performance as Windows 7 was as the install ages. I'm running 8.1. Very underrated Os imho once you swap out the start menu.

My system is running as I want it to so all drives relevant to me work. I usually disable the chipset in Device manager and have for the last ~10 years. Everything it needs to run it runs from the bios. Haven't installed the ME/Inf drivers either, they are simply not needed.

Anyways, you seem to confirm my suspicions that it's not really need to reinstall. Thanks!

Every OS (especially Windows) is susceptible to malware. Only idiots install crap like that anyway, it's very difficult to just get malware without doing it yourself.

Of course the old maxim is that you should reinstall Windows every time you swap motherboards. I fail to see why though. I also, after about 36 hours, can't see any reason. There is no lag, no performance issues, no stutter or anything else I detect that's wrong.

Why should one reinstall?

Ps. Sorry if this is the wrong thread, I felt it more appropriate here than in the Windows forums.

Long live 4790k! I will forever cherish our moments together! But a few minutes? When I reinstall it takes a day until my system is the way I like it. Sure, install ~20 minutes. Updates ~2-3 hours. Configuring, basic~2 hours, full a week or so .

Unless you talk about the win 10, is it called refresh? I don't use windows 10 cause malware.
May be drivers problems ,you can try use driver booster free to remove all of them like image(but care when setup, don't click to install ads):

But i still suggest you reinstall fresh windows for best performance.
