I recently upgraded my motherboard and RAM from GA-790GP-UD4H to GA-970A-DS3P
Graphics card: GTX 550Ti
RAM (new): 8GB DDR3
Chip: AMD Phenom x4 965 BE (all cores unlocked in UEFI Bios)
Disks: WD Black Caviar 1TB: 2 disks (OS on one, Game on another).
WD Green: 500GB (for swap and docs)
Before upgrading my mobo, I had a score of 7.3 (lowest in Disk) under the Windows Experience Index.
Windows: 7 64-bit.

After upgrading the hard disk score dropped to 5.9. Other scores remain high above 7.3

When I tried in CoH2, my lowest FPS was 0.78 and maximum was 29.78. This on low settings, FXAA turned off, AA turned off and Snow to low.(It really doesn't matter which setting I chose, since FPS avg remained below 28)

I have tried removing and reinstalling he RealTek audio drivers and configuring the same based on an advice in Steam Forum (like disabling sound effects, etc).
I have also removed all traces of old drivers (ATI Catalyst crap) via DriveSweeper based on advice given in this forum.

Cleaned out registry using CCleaner.

Have used DriverMax to install latest drivers.

Rest all operations on PC are fast, like booting under 55 seconds, launching Word, etc.

During game, the CPU usage remains about 30-40%. while GPU temp goes to 58 C. (I use EVGA Precision to regulate fan speeds).

Without reinstalling Windows 7, what else can I do?
(Pls. do not suggest reinstalling Windows 7 -:)

Thanks for taking time to answer my issue.

1) Yes, GPU plugged into 16x PCIE slot.

2) BIOS ver is F1, the latest one.

3) BIOS is set to AHCI and SATA.

PSU is 650W

I have even tried cleaning every chipset driver, graphics driver and realtek using Drive Sweeper and then reinstalling one by one everything and rebooting.

Still the same problem.

*Edit*
Is there a separate SATA cable for SATA-3 and SATA-2? I see a blue SATA cable from hard drive to the SATA-3 port 0. (Primary drive)
The other 2 drives have SATA green cables on port 2 and 4.
Is this OK?

Wiped windows, and reinstalled windows fresh, updated everything and installed basic stuff like winrar and Acronis. Took steam backups of games.

Installed basic gigabyte drivers for sata and usb3.
Took an Acronis backup and hope to try installing steam tomorrow and try it again.
