Fresh Windows install lagging horribly, please assist!

[Tenino]

Hey all, I made a few upgrades to my computer today. As per my luck, something's gone horribly wrong, and I can't really figure out what. My fresh install of Windows (8) is lagging like crazy, to the point where it's practically unusable. If anybody here thinks they might be able to discern why, some help would be immensely appreciated!

So my friend was upgrading his own comptuer, so I bought his mobo, CPU and GPU. All three parts were working fine, and he's not the type to nickel and dime me. I also bought brand new RAM and an SSD. Here are my specs:

Operating System: Windows 8 64 bit (new, legal, fresh install)
Motherboard: Gigabyte GA-EX58-UD4P (used)
CPU: Intel i7 920 (used)
GPU: EVGA GTX 560Ti (used)
RAM: 32GB (4x8) DDR3 Corsair Vengeance (new)
Storage: 250GB Samsung SSD 840 Series (new)
PSU: Corsair HX750W (from previous build)

Task Manager says that the CPU is struggling, to say the least. I'm idling at ~20% CPU usage, which spikes to ~60% whenever performing basic actions like right clicking, and to ~90-100% whenever switching windows/tabs, loading pages, etc. Needless to say, all of these actions happen dreadfully slowly. 

I'm always extremely careful/clean with electronics, so I would like to think that the cause isn't user error. Signs point to the CPU being busted, but it was working just before I put it in my computer, and all I did was alcohol swab off the leftover thermal compound to reapply a fresh layer of paste. All fans are running properly, as well. I've updated my graphics drivers, so it's probably not that either.

Here's a screenshot of my task manager, RealTemp and GPU-Z:

And here are some BIOS screenshots:

Any help would be most appreciated!

Try flashing the BIOS on your motherboard and reinstalling the motherboard drivers

this ^^^^ and try a reinstall of the os too ... do a format of the drive in which you install the os also

Here is what I have done so far:

Disabled Drive A (Floppy)

Changed first boot device to SSD

AHCI mode enabled then re installed windows. 

Ram was running at 1066 with 7/7/7/20/2 timings, changed to the default 1600mhz 10/10/10/27/2, x12 multiplier. 

 

After all these changes, I am still experiencing the same problems.  

How can I check the current bios version my motherboard is on? 

 

(Could CPU settings in the bios be the causing this problem?)

there is no update link for windows 8 so maybe something isnt compatible with windows 8. maybe get windows 7 that may be the issue.

I have to go but ill be back in like an hour and then I can give you the link to where I got my windows 7 and everything.

Sorry I wasnt able to get in on but...
ISO: http://www.w7forums.com/official-windows-7-sp1-iso-image-downloads-t12325.html

geniune maker thingy: http://www.mediafire.com/download/t50hvnv39djk3nb/Windows7Loader.zip

(I just uploaded it to mediafire myself, the build and everything you delect doesnt matter)

I think you just out the iso on a dvd

install it

then make it genuine, its been just under a year since I did this.

Not exactly legal but just use it to see if windows 8 is the issue and then buy windows 7 legit if you want to suppport microsoft, even though you already have bought a possibly faulty product.
