PC running slower after upgrading cpu and motherboard

[Arcade]

I recently upgraded from an fx-8350 with an msi mobo to an i5-6600k and asus motherboard and my os (win10 64 bit) is really laggy and performance in game is about the same if not worse. From what i looked at it seems that I need to do a fresh install of windows and that should fix the problem. I just want to confirm that this is the cause of the problem or if i should be looking at the hardware as an issue. The other thing of note is that post does one short beep everytime i turn on the devise. Any help would be great thanks!

current setup:
i5-6600k
msi r9-380
asus z170-e mobo
thermaltake water 3.0 extreme s liquid cooling
corsair rm850 psu
16 gb ddr4
250 gb ssd (for os)
1TB drive
500GB drive
2TB drive

You would usually need to reinstall windows when changing motherboard.

Off topic: Can i ask why you have 3 different size drives for data? wouldnt it be simpler to have 2 2tb or 1 4tb?

[TeKraken]

That's what happens when you add a new drive into a system. Not everyone bothers to consolidate data or just chooses to keep different items on different drives. Maybe the 1tb is wd black and the 2tb is wd green...etc.

Check your gpu % load with msi afterburner or similar app. If the gpu is the limiting factor, then changing the cpu may not improve things.

I've done it twice now without bothering to reinstall windows. No issues each time.

What hardware were you moving to and from?

You should reinstall Windows because the hardware drivers are a lot different. You also need to reactivate Windows.

It took a dozen reboots for windows to detect and install all the proper drivers, and it did ask to be reactivated, but it's up and running for me now.

@OP: However! If I was experiencing issues like you, the first thing I would do is a re-install just to rule that out.

just reinstall windows

swapping from amd to intel hardware windows will never pick up all the chnages correctly
