Firstly im sorry if this is the wrong place. Ive been having a problem with my pc for the last couple of months and ive put if off till now.

When i first start my pc it loads to the desktop fine but then gets really slow and sluggish untill i restart and then everything works normaly if i then restart my pc again its back to being slow till i restart it again.
so every 2nd boot my pc is really slow

I checked task manager today and cpu speed varies roughly between 2.27 and 3.90 GHz (idle)

After i restart and look at task manager my cpu speed suddenly drops after a few seconds to 0.40 GHz and stays there untill i restart again and its back to 2.27 - 3.90 GHz. any idea whats causing this?

My pc specs are ''Titan Wave'' ordered on 26 Nov 2015
i7-5820k @ 4.00 Ghz
MSI GTX 980TI
16GB DDR4 2400MHz
Gigabyte X99M-Gaming 5 MATX Motherboard
SuperFlower 650W Power Supply
Samsung 250GB SSD
1TB HDD
OcUK Techlabs 240mm AIO Liquid Cooler
 
My power plan setting is set to high performance already

CoreTemp shows all my temps are in the 30's

Using Task Manager i see i have 36-40 background processes running. how can i tell which 1 is may be causing this?
 
To clarify when i first boot my pc in the morning after a few seconds i see in task manager my cpu speed drop from 2/3 Ghz to just 0.40 Ghz and it stays at that
speed making any programs (like firefox) open slow new tabs open slowly too, even the right click menu on desktop takes seconds to load and so does the start menu.
If i restart my pc then it works perfectly with programs/menus/tabs opening near instantly and my cpu speed back upto 2/3 Ghz but if i have to shutdown or restart my pc
the cpu speed goes down to 0.40 Ghz once again so every other boot theres a problem

ive just restarted again and with my cpu speed at 0.40 Ghz utilisation is 1%-2% the highest process is Smilnfo (32 bit) at 1.1%
then there are 9 or 10 at 0.1% and the rest at 0%

This is with my pc running slow

and this is after a restart

i see that the multiplier is different why would that be?
 
in example A (the first screen shot) the multiplier stays at 8x and doesnt go up

in example B (after i restart) the multiplier changes from 12x to 40x which i understand is normal

but if i restart my pc a 2nd time then it stays at 8x, restart a 3rd time and its back at 12x - 40x and so on.
If i use the ''Sleep'' option instead of shutdown/restart this doesnt happen and the multiplier stays at 12x - 40x so basically i cant shutdown or restart my pc without having to restart it again once its booted because the multiplier gets stuck at 8x everyother boot

What happens if you run cinebench when its booting only at "8x", keep cpu-z open and watch what happens while you run it.

i restarted and ran the test with 8x mutiplier my cpu scored 93 and the mutiplier didnt change

restarted again and scored 1174 with a 40x mutiplier
