Windows Randomly Freezes when Resource Monitor Disk Highest Active Time Maxed Out

Question

I'm getting this same problem as this person:
http://social.technet.microsoft.com/Forums/en-US/w7itproperf/thread/4e33c8d9-fc3d-434b-8dd0-29965d1aa0a2
Except that it seems to happen at random.  While playing a game, browsing the net or when it's just sitting idle.  
Hard drive light goes solid, the blue line (% highest active time) in the resource monitor disk graph stays peaked at 100% but
relatively little or no hard disk activity.  
My mouse is also usually still responsive. 
Some apps will continue to work, but if I click on them they will usually become unresponsive, same goes if I attempt to click on the Windows Start button.  If I'm playing a game, it will stutter or freeze and a .5-1 second sound clip will continuously loop
until it's done (meaning the hard drive light is no longer solid and blue line is no longer peaking). 
It is also the same for me that occasionally the OS will freeze completely and I will need to hold down the power button to reboot, but this is usually more rare.
I've checked the Event Viewer and there are no errors that coincide with the problem. 
I've run chkdsk and no errors were returned.  Same when I ran Memtest86+ to check RAM, no errors.
My stats are:
-Windows 7 Ultimate 64 bit SP1
-Intel Core i-7 960 3.2Ghz 
-eVGA 132-BL-E758-A1 X58 Motherboard
-Corsair Dominator 12GB TR3X6g1600C8
-eVGA 012-P3-1472-AR GeForce GTX 470 (Fermi) SuperClocked 1280MB 320-bit GDDR5 (x2 SLI)
-CORSAIR HX Series CMPSU-850HX 850W ATX12V 2.3 / EPS12V 2.91 80 PLUS SILVER Certified Modular PSU
-VelociRaptor WD3000HLFS 300GB 10000 RPM 16MB Cache SATA 3.0Gb/s HDD (x2 RAID 0)

Hi,
How about updating the BIOS and all devices' driver from the manufacture's site?
I suspect it is the task schedule running in the background. If you want to narrow down the issue, you may need some monitor tools and then analyze.

To analyze the process, it is better to contact Microsoft Customer Service and Support (CSS) via telephone to get more efficient support.
Microsoft Customer Service [phone] is available Monday through Friday, from 6:30 A.M. to 5:30 P.M. pacific time.
