Windows 7 64 - bit, GA-970-a-DS3P, slow SATA 3 HD and USB 2.0 also issues

Let me start this way:

Material:

Motherboard: GA-970-a-DS3P

(1) WD Caviar Black HD: 3 amendments of 1 TB each. One for the OS, one for applications and one for Swap. (Don't ask how I ended up with this config: it's a long story of upgrade).

(2) graph GTX 550 Ti card.

(3) AMD Phenom x 4 965 BE: all 4 cores unlocked. DO NOT overclocked.

(4) RAM DDr3 8 GB (2 sticks)

(5) rest include 1 SATA DVD drive, Cooler Master monstrous fins CPU cooler (which cuts my fingers twice) and a power supply 650W (Cooler Master)

Software:

(1) Windows 7 64 bit ultimate (new installation)

(2) MS Office 2010

(3) Acronis True Image 2012

(4) cloud of Creative adobe: Adobe Acrobat Pro XI

The ORGANIC parameters:

a value of 1) all SATA AHCI.

(2) active xHCI. (no idea)

(3) active eHCI. (no idea)

Drivers:

1st install Gigabyte SATA AHCI and USB 3.0 drivers drivers. All keyboard & mouse drivers are from Gigabyte.

2nd configuration (after that I discovered that it was slow death): DriverMax provided SATA 3.0 AHCI drivers.

Windows start up the GUI login screen in 40 to 43 seconds after the POST.  (Used to make less than 30 seconds before I installed MS Office).

Problem and diagnoses that I made:

(1) primary HD is extremely slow to respond. It takes just an inordinate amount of time to respond to the high activity of HD. (Like when I try to copy a large file on the C drive or read from drive C).

(2) I used Perfmon.exe to monitor disk queue length and % disk time Avg. Length of queue disk on drive C starts from 0.117 and amounts to 24,26 within 20 minutes once I started. % disk time is high at 118.98 or even above.

(3) surprisingly a USB 3.0 flash drive has reported a speed of 118 MB/s on a copy of a file of 3.4 GB D USB 3.0 drive

(4) USB 2.0 reported avg 28 MB per second, which was expected.

(5) after that I removed the drivers from Gigabyte SATA, I used one of Drivermax (don't know what it was).  Yes, I remove the old drivers, rebooted and then installed drivers drivermax.

(6) disk queue length dropped to 0.28 on average when copying to and from the drive C and even under heavy operations.

(7) Windows experience index stays at 5.9 for HD primary.

(8) Avg speed of drive C is now about 128 to 132 MB/second (seriously?)

(9) I don't find the exclamation points or question marks in Device Manager.

(10) now, since yesterday, the speed has dropped again down (no updated driver, but the critical Windows updates made). Avg disk queue length again increased slowly to about 24.23.

(11) what I did a chkdsk c: R, but could not find any errors of surface HD.

(12) I am past controller cables and plugged in the different plugs (which cut on sharp edges of the graphics card and the fins of the cooler: why HW manufacturers can soften the edges: they will lose money?).

(13) USB 2.0 speed has dropped drastically to 7,28 MB/second copy about 1 GB of multiple files of 12 MB each.

Am at the end of my rope on this.

Can I have a very problematic motherboard? Have I not dumb drivers? Or I did something wrong here?

Any help to fix this problem of speed appreciated.

P.S. The system is also catchy and fast with start-up less than 45 seconds, even times with connected devices. Opening apps are fast and load system (also long that I do not touch the C drive) are faster.

Thanks in advance

I misinterpreted the word 'no'... :-)

Clone of the boot drive on the disk used for the page file after removing the partition on the drive of page file as in reduce to unallocated space. Your current boot drive is perhaps not the strongest of its kind.

It can be done with the help of Aomei partition Wizard, free for home use.

If the computer seems to be ok, stop the execution of the performance monitoring software. It can drive a person crazy. Glance for other stuff that can slow the system down...
