Q: Random system hangs/freezes. This thread is locked from future replies

I have been banging my head against the wall trying to figure this one out.  I am currently running Windows 7 x64.  At any given moment, the system will hang.  Sometimes the system will go days without any issues, sometimes it will hang several times during one day.  First the screen will freeze and all open programs become unresponsive, the mouse will continue to move around the screen as normal for about thirty seconds, but this time varies.  If I am watching a video or playing music, the audio will continue without interruption for several minutes, but this time will also vary.  The caps lock, scroll lock, and num lock lights will continue to work also, meaning if I press any of the affor mentioned buttons, the light turns on/off like normal.  The mouse, keyboard lights, and sound usually continue to work until I click the mouse buttons several times, at which point the system becomes entirely unresponsive. 

My first instinct was driver issues.  Noticing that the screen froze first, I assumed that the VPU was crashing and failing to recover.  After several driver updates and much online research to this end, Nothing had changed.  I then turned my attention to drivers in general, updating all that I could, this again yielded no results.  I then updated my BIOS and had no luck.  assuming it was not a driver issue, I examined my hardware.  I thoroughly tested my hard drives, RAM, and monitored loads and temperature on the CPU, VPU, and chipset.  I could not see any trends, the freezes appear to be at complete random.  I do have an early AMD Phenom 9600 with the TLB erratum.  I have tried enabling and disabling the patch in the BIOS with no change.  At this point I do not know what else to check.  This is my most powerful PC at the moment, and I have reverted back to XP Pro x86.  I really like 7 over XP, but the instability in 7 makes it difficult to use for fear of data loss.  XP has no stability issues running on this same system.  I have four other PC's which also have Windows 7, none of them have had any issues.  Some are 64-bit, some are 32-bit, all are stable.
My system specs are below:
This is with the system at idle.

Hi nate0031,

Try the below troubleshooting steps and get back to us with results:

Step 1:

1. Run the Performance Troubleshooter that would help us diagnose the issue better.

2. Access the below link to know more about Performance Troubleshooter:

Step 2:
If the above steps is of no help, then put the computer in a Clean Boot state and then check for the issue, one of the third party services could be causing the issue. Below are the steps to put the computer in a Clean Boot State:

1. Click Start, type msconfig in the Start Search box, and then press ENTER.

 If you are prompted for an administrator password or for a confirmation, type the password, or click Continue.

2. On the General tab, click Selective Startup.

3. Under Selective Startup, click to clear the Load Startup Items check box.

4. Click the Services tab, click to select the Hide All Microsoft Services check box, and then click Disable All.

5. Click OK.

6. When you are prompted, click Restart.

7. After the computer starts, check if the issue is fixed.

If your issue is resolved after performing Clean Boot, then follow the steps mentioned in the following KB article to narrow down the exact source: 

Also, see the section on how return your computer to a Normal startup mode by following the steps under “Reset the computer to start as usual”, after performing the clean boot troubleshooting.

Step 3:

I would also suggest you to check Event Viewer entries to find the faulty module that could be causing this issue.

1. Open Event Viewer by clicking the Start button, clicking Control Panel, clicking System and Maintenance, clicking Administrative Tools, and then double-clicking Event Viewer.‌

If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

2. Click an event log in the left pane.

3. Double-click an event to view the details of the event and let us know the faulty module that is causing the issue.

Access the below links to know more about Event Viewer:

4. Also check how much memory and CPU resources are being used.

Access the below link to know more information about Performance and Resource Monitoring:

Hope this helps. Get back to us with results.
