Windows 7 Home Premium 64-bit, encountering random freezes

Hi everyone!

-Have been using Windows 7 32 and 64-bit Enterprise and have encountered no random freeze problems
- Now using Windows 7 Home Prem 64-bit
- reloaded this os twice, second time started having random freezes

Preceding events
- changed GPU card (Geforce 310M) 2 x
- changed motherboard 2x
-changed internal hard disk
- tried downloading hotfix (see below) but encountered error message: This update is not applicable to your computer. My Windows version. 6.1.7601 SP1 build 7601 Compatible OS: 6.1 .7600

-Having video hardware error
-from 07/02/12-15/05/12
-comes once-thrice every 3 weeks
-now video hardware error is not really a concurrent problem

Difference between a freeze, hang and crash
crash known as APPCRASH
Hang known as hungapp or apphang
freeze is unresponsiveness where by for e.g. when u r typing, the screen just stops in mid air , no pressing keys, mouse, CTRL-ALT-DEL, restart, task manager only to force power off by turning off power or pressing power button manually

Reason for having freeze problems (more so for 64bit windows 7)
Microsoft has released a hotfix...
significant problem: A computer that is running Windows Server 2008 R2 or Windows 7 stops responding randomly. Reason: heavy GPOs (group policy) use and SCOM and a situation of nonresponsiveness between the Lsass.exe (Local Security Authority Subsystem Service), Rdbss.exe (Redirected Drive Buffering Subsystem) and Winsock kernel
causing hangs and unresponsiveness

TRY THIS!
REASON:
is to delay the signals from the keyboard significantly longer than the mouse and other USB devices to prevent any race conditions.

SOLUTION:
attach an extra USB hub to the keyboard cable to increase the electrical delay How: Get a cheap USB Hub

RESOLUTION:
Paul (a person who has tried this method) says he hasn't had one lockup since implementing this solution

I have attached many .png files. They are system snapshots. Hope that that will provide more than enough info to diagnose the problem I know there are many files but it is not exhaustive.

Establish a clean boot and test HD and RAM as well as other steps from these Troubleshooting Steps for Windows 7.

I'd also post up the bluescreen bugcheck to our Crashes forum for expert analysis: Blue Screen of Death (BSOD) Posting Instructions - Windows 7 Forums

Did you run for awhile with drivers given by the installer and quickly updated via optional Windows Updates, after enabling Automatically get recommended drivers and updates for your hardware?

Or did you immediately change out drivers Win7 wanted with the factory chipset and other drivers? This can be a problem.

If the troubleshooting doesn't solve it then I'd consider a baseline perfect Clean Reinstall - Factory OEM Windows 7 - the steps are the same for retail.

Thank you for the information.
