Windows 10 - 100% CPU usage (also mathematically impossible values under the Resource Monitor)

Hello there!

I apologize if this has been posted and answered before, but unfortunately I couldn't come across an answer that I could, as far as I know, perform on my end without the risk of running into issues afterwards.

I've been hearing lots of good things about Windows 10, enough for me to want to try it out. Sadly, I've been having issues with my CPU Usage. When I view my Task Manager, it's sitting at 100% constantly, people have reported this isn't an an aesthetic issue but a practical one (CPU-Z for example reports higher power consumption.)

In addition to that, when I view the Resource Monitor on the CPU, I'm getting mathematically impossible values such as 2 million percent and the like.  Here's an image from another forum of the issue that I'm having:

Interestingly enough, the issue doesn't persist if I switch to Safe Mode; however it does if I'm only using Selective Startup with non-Microsoft services disabled. This would imply it's some service or driver that doesn't boot up in Safe Mode, but I'm not quite sure what that might be.

I've read most people with this issue have been on Sandy Bridge CPUs and some of them have managed to fix the issue by updating their BIOS version. Unfortunately for me, a BIOS update doesn't seem feasible as ASRock's latest BIOS versions are mostly to add support for Ivy Bridge CPUs, which tend to cause issues for Sandy Bridge users. These issues include but are not limited to Blue Screens, which I'd rather avoid as my current BIOS version has no other issues. (I'm also not seeing the 100% CPU usage issue on Windows 7 x64, so it's only on my Windows 10 Home x64 [Even there the Safe Mode works fine.])

I'd appreciate any ideas one could bring up. Thanks beforehands!

My specs are as follow:

Processor Intel Core i5 2500K @ 3.3GHz
Graphics Card MSI Nvidia GeForce GTX 970 Gaming 4G
RAM 8GB DDR3 1333MHz CL9 240pin DIMM
Storage Crucial MX100 256GB SSD, 2x 1TB @ 7200rpm HDDs
Motherboard ASRock P67 Pro3 (B3 rev) with BIOS v1.8
Operating System Windows 10 Home 64-bit

During the trace your computer was 96.69% idle.  Were you having the problem during the trace.??

The instant I brought up the Task Manager, I saw 100% CPU Usage (while no process was using anywhere near that), and some million CPU Usage % under Resource Monitor.

Yes.

Shall I run this in Safe Mode too (to create contrast)? (I don't have this issue there, I only have it in Normal Boot & Selective Startup w/ non-Microsoft services disabled.)

EDIT: Note, I probably have this everywhere but in Safe Mode, I've only tried those two alternatives to boots.

EDIT 2: I've tried stuff like sfc /scannow and unfortunately it's failed to bear fruit. (Found no errors)

Apologies for the bump, but I felt I'll add a video (and new logs) to further demonstrate this.

Normal boot and Selective Startup with non-Microsoft services disabled is video recorded; whereas Safe Mode is just a still picture in the end, because Nvidia GeForce Experience Shadowplay would refuse to work while in Safe Mode.

As I mentioned in my previous post about making the contrast, I chose to run Selective Startup (issue persists) and Safe Mode (issue doesn't persist); as well as re-do the normal boot with the Nvidia GeForce Experience Shadowplay (the recording program) running on the background.

Video can be streamed from here.

Alternatively, downloaded from here.

Should there be any doubt in my issue, the filenames & sizes are shown in the end of the Selective Startup -part of the video and should match the unzipped files linked below.

Logs:

Again, apologies for the bump. Thank you very much if you can figure anything out of the little I've thought to provide. Do ask if any information is required and I'll do my best to provide it.

Sidenote: I also took down the former reply's "unzipped" -version, as it took a lot of space from my Dropbox and was an accidental upload to begin with.
