Blue Screens and Freezes still going on randomly

I haven't been able to get my system running stable since a clean install of Windows 7 Professional 64 a few months now. The computer is about 3 years old. Local pc tech shop installed 7 64 Pro on a brand new hard drive (2 months ago) that was tested prior to installing the OS.

I've included required reports. I believe my memory has been thoroughly tested and is running well. The only thing I haven't done is uninstalling Avast though not sure why it would be a problem software.

Thanks in advance for help!

Avast was implicated in at least 3 of the 5.

Avast can be a contributing cause of BSOD'S . Please remove and replace with Microsoft Security Essentials AT LEAST TO TEST

Microsoft Security Essentials - Free Antivirus for Windows

When you say 3 of the 5 I assume you are referring to the reports I generated?

Yes the DMP files (logs of the crash)

I uninstalled Avast, installed MS Security Essentials. Computer runs stable for many hours but then freezes up randomly. I also had a BSOD / Stop error in which no dmp file was created.

I think this is a driver issue but not sure how to solve it. I suppose driver verifier is my only option going forward unless perhaps there is an easier way to check what is causing the freezes. Nothing in the event logs indicates problems.

Any suggestions?

TIA

Freezing can be software related, but since the advent of Windows XP, that is rare. It is usually hardware that causes freezing.

• If you are overclocking any hardware, please stop.
  
  
  
• Monitor temperatures during the following tests.
  
  Use the following programs to monitor the temperatures.
  • Real Temp is a good CPU temperature monitor.
  • Speccy - System Information - Free Download will monitor all hardware temperatures.
  • HWiNFO, HWiNFO32 & HWiNFO64 - Hardware Information and Analysis Tools can be inaccurate for CPU temperatures, but is a good program for GPU temperature monitoring.
  
  
  • Use FurMark: VGA Stress Test, Graphics Card and GPU Stability Test, Burn-in Test, OpenGL Benchmark and GPU Temperature | oZone3D.Net to test the graphics card GPU. Let it run until the GPU temperatures even out or until the GPU temperatures reach a dangerous level (you can find the max temperature for your card on either the nVidia or AMD sites; if you are not sure, ask us). Then use the |MG| Video Memory Stress Test 1.7.116 Download to test your graphics card memory. Let the memory test run for at least seven passes; the more the better.
    
    
  • Run Hardware - Stress Test With Prime95 to determine any hardware problems. Run all three tests for a few hours each. If you get errors, stop the test and post back here.
    
    
  • Follow the steps for doing a CPU stress test using IntelBurnTest
  
  
• Run the boot version of Memtest86+ paying close attention to Parts 2 and 3 of the tutorial. Also, in case Memtest86+ misses anything and comes up with no errors, run the extended version of the Windows Memory Diagnostics Tool for at least five passes. These you may want to run overnight since they take a long time to complete (run them an hour before bed each of the next two nights and check before going to sleep that they are still running).
  
  If you swap any memory components, follow these steps for ESD safety:
  
  1. Shut down and turn off your computer.
  2. Unplug all power supplies to the computer (AC Power then battery for laptops, AC power for desktops)
  3. Hold down the power button for 30 seconds to close the circuit and ensure all power drains from components.
  4. Make sure you are grounded by using proper grounding techniques, i.e. work on an anti-static workbench, anti-static desk, or an anti-static pad. Hold something metallic while touching it to the anti-static surface, or use an anti-static wristband to attach to the anti-static material while working.
  
  Once these steps have been followed, it is safe to remove and replace components within your computer.
