Windows 10: Major stuttering a few minutes after boot

I want to make sure to give as much info as possible so this will be a bit long but bear with me.
Up until recently i had a PC with these parts. I've used it for a year with no problems at all. Only very rare and minor stuttering nothing major. Recently I've bought anew PC that essentially switches out all the old parts except the storage. When I built my new PC i didn't do a fresh install of Windows but just installed my old boot device as is. At first it ran fine but i had that weird issue where after the first boot of the day i would get constant stuttering in and outside of games affecting video and audio. The issue was easily resolved by just restarting the PC. I was told that me not doing a fresh install of windows, keeping all my old drivers and stuff could lead to some issues, so i tried to manually delete all old drivers. To no effect sadly, the stuttering persisted. After that i tried doing a reinstall of windows where i would still keep all my files but that didn't help either. In fact it made the problem worse, as now after running the PC from around 14:00 where I would boot the PC for the first time, get the stutter and then restart it, up until around 23:00 of no issues the stutter would suddenly reintroduce itself, whereas before it wouldn't happen again for that day after a restart. I tried some more tips i found online, updating the drivers, reinstalling the Memory, disabling A-XMP, all didn't work and with each reboot the problem got worse and worse where now after every boot and every restart the PC would always stutter maybe 5 to 10 minutes after booting. The only other thing i could try but want to avoid until nothing else works would be to completely reinstall windows and wiping all my data. Is there anything else I can try? I'm at my wits end.

Mouse stutters on start up, but works normal after a few minutes

I've recently got a new computer, and I've noticed when I turn it out, the mouse stutters at first. For the first few minutes, I can move the mouse for a second, then it freezes for a few seconds, then it moves for a second again, etc...

I've currently not got another mouse to try with, but I wondered if any body had any suggestions I could try whilst I try and source another mouse to test with.

I'm running the following

1. Win 10 Pro
   
2. i7-4790K (Not overclocked)
   
3. 16gb ram (this was salvaged from my old computer, so it's a few years old)
   
4. Nvidia 980 ti
   
5. Mouse is a Razor Oubourous.
   

If you need any more info, or specs, let me know and I'll add them.

 

Win 10 x64 - Random mouse stuttering/freezing (again)

And we're back. After a few days, the stuttering returns. Booted up one game, and it was back within minutes. Got any other suggestions?

 

FPS drops below 10 every couple of minutes

Very interesting. Our default suggestion list for fighting stutter becomes more interesting.
