Persistant BSOD at various times, no noticeable trends.

Hello Everyone.

I have been getting the occasional BSOD the past month or two which I shrugged off and presumed to be driver based. After updating on each occasion and not getting one for a few days, I just assumed the problem would go away. It's been getting more and more frequent recently and after uninstalling all Firewall and antivirus programmes and still getting crashes this morning I am at the end of my patience, so I now seek your help. :)

Here is the hardware details as instructed in the thread:

- I am running Windows 7 Ultimate 64 Bit
- The original installed OS is Windows 7 Ultimate
- Full Retail Version
- The system is about a year and a half old.
- I reinstalled Windows in January more as a clean up than because of problems.

I will post a few hardware information too, I hope this is helpful:

- ASUS M4n68T-M LE Mobo
- AMD Athlon II X3 440 Processor (3 CPUs), ~3.0GHz
- Nvidia GeForce GTS 450 Graphics Card
- 4 GB RAM
- Previously had AVG and ZoneAlarm installed, both uninstalled, still get BSOD (I am aware Antivirus, particularly AVG, is a common cause of BSOD)

I keep all my drivers up to date as much as possible out of habit.

Attached to this post is the necessary dump info as requested. Any and all hope eradicating these errors is much appreciated. :)

I just received another BSOD a moment ago, this time there was no error message to indicate what the specific error was nor what file or driver failed, however I did write down the bugcheck code. It was 0x1000007E. Sorry for bumping the topic to post this information.

Security Software: ??? Make sure to install security software. I recommend either of these:

• Microsoft Security Essentials - Free Antivirus for Windows coupled with Malwarebytes. Do not start the free trial of Malwarebytes. Just use the standalone version, update it, and scan your computer once a week with Malwarebytes and with Microsoft Security Essentials.
  
  
• Good and Free system security combination.

After installing your security software, update it, and then run full scans today with each program. Report back the results of the scans.

Code:

ASACPI.sys Sun Mar 27 20:30:36 2005 (42476C4C)

• Older versions of ASACPI.SYS are a known BSOD problem on Windows 7. Update the driver by:
  
  1. Going to the Asus motherboard support site
     When you reach the website:
  2. Scroll down the page and click Utilities
  3. Hold Ctrl and press f (ctrl+f) to enter the browser's find feature
  4. Search for "ATK0110 driver for WindowsXP/Vista/Win7 32&64-bit" (without quotes)
  5. Download and install the driver.
  6. After installation is complete, verify that it installed correctly.
     
     • Click Start Menu
     • Click My Computer
     • Go to C:\WIndows\System32\drivers\
     • Verify that the ASACPI.SYS file is dated 2009 or newer (2010,etc.)

Your crashes all have varying BugCheck codes. This generally means you have a hardware issue. Run some hardware checks.

• If you are overclocking any hardware, please stop.
  
  
• If you have an SSD, make sure the following are up to date:
  • SSD firmware
  • BIOS Version
  • Chipset Drivers
  • Hard disk controller drivers/SATA drivers
  • If you have a Marvell IDE ATA/ATAPI device, make sure the drivers are up to date from the Intel site or Marvell site and not from your motherboard/vendor support site.
  
  
  
• Run all but the advanced tests with SeaTools for HDDs.
  SeaTools for Windows
  
  SeaTools for DOS
  
  
• 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). The goal is to get a steady temperature, find out if the GPU is overheating, or to see if there are any artifacts present in the test itself: look for strange pixelated patterns on the screen or colors that do not look like they belong. 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 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).
  
  
     Warning

  Before you proceed with the following, answer these two questions: Are you still under warranty? Does your warranty allow you to open up the machine to check hardware? If you are unsure of the answers to these questions, contact your system manufacturer. WARNING: The steps that follow can void your warranty!!!
  
  
  For Part 3: If You Have Errors: 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. If you do not have an anti-static workbench, desk, or pad, you can use your computer tower/case by finding a metal hold in it, such as a drive bay.
  
  Once these steps have been followed, it is safe to remove and replace components within your computer.
