BSOD-computer crashes all the time

[anze87]

I have got a laptop HP Compaq 6820s with Windows 7 proffessional-32 bit operating system. OS has got student license. I think this crashes started about a year ago, maybe more. I am not good at computers, so I just rar BSOD files using BSOD posting instructions. I will be very happy, if someone could help me with that, because it is really annoying.
Thanks for help!

Easy your avast.

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

Hello,

from the time that I uninstall Avast, computer still crashed 3-times till today, same blue screen. Have you got any ideas, what else could be wrong? It is really not cool, when it crashes during some important work.

Thanks for help!

If you are still crashing, we still need the DMP files. without them we are blind.

 

[anze87]

New DMP files. Thanks for helping me.

These crashes were caused by memory corruption/exception (Cx05) probably a driver.
Please run these two tests to verify your memory and find which driver is causing the problem.

* If you are overclocking anything reset to default before running these tests.
In other words STOP!!!

* If you have a Raid update its Driver.



Memtest.

*Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program. Memtest86+ - Advanced Memory Diagnostic Tool

*Boot from the CD, and leave it running for at least 5-7 passes.

Just remember, any time Memtest reports errors, it can be either bad RAM or a bad motherboard slot.

Test the sticks individually, and if you find a good one, test it in all slots.

Any errors are indicative of a memory problem.

If a known good stick fails in a motherboard slot it is probably the slot.

Driver Verifier

Using Driver Verifier is an iffy proposition.
Most times it'll crash and it'll tell you what the driver is.
But sometimes it'll crash and won't tell you the driver.
Other times it'll crash before you can log in to Windows.
If you can't get to Safe Mode, then you'll have to resort to offline editing of the registry to disable Driver Verifier.

I'd suggest that you first backup your stuff and then make sure you've got access to another computer so you can contact us if problems arise.
Then make a System Restore point (so you can restore the system using the Vista/Win7 Startup Repair feature).

In Windows 7 you can make a Startup Repair disk by going to Start....All Programs...Maintenance...Create a System Repair Disc - with Windows Vista you'll have to use your installation disk or the "Repair your computer" option at the top of the Safe Mode menu .

Then, here's the procedure:
- Go to Start and type in "verifier" (without the quotes) and press Enter
- Select "Create custom settings (for code developers)" and click "Next"
- Select "Select individual settings from a full list" and click "Next"
- Select everything EXCEPT FOR "Low Resource Simulation" and click "Next"
NOTE: You can use Low Resource Simulation if you'd like.
From my limited experimentation it makes the BSOD's come faster.
- Select "Select driver names from a list" and click "Next"
Then select all drivers NOT provided by Microsoft and click "Next"
- Select "Finish" on the next page.

If you are using win 8 add these
- Concurrency Stress Test
- DDI compliance checking

Reboot the system and wait for it to crash to the Blue Screen.
Continue to use your system normally, and if you know what causes the crash, do that repeatedly.
The objective here is to get the system to crash because Driver Verifier is stressing the drivers out.
If it doesn't crash for you, then let it run for at least 36 hours of continuous operation.
Reboot into Windows (after the crash) and turn off Driver Verifier by going back in and selecting "Delete existing settings" on the first page, then locate and zip up the memory dump file and upload it with your next post.


If you can't get into Windows because it crashes too soon, try it in Safe Mode.
If you can't get into Safe Mode, try using System Restore from your installation DVD to set the system back to the previous restore point that you created.

Sorry for late response, but I didn't find time for repairing my computer. I tried Memtest86+, but when I run this program, computer shuts down after about 2minutes or earlier, when it is around 2%. In longest case it came to about 5%, then shuted down. What does that mean?

 

[writhziden]

It means you have a hardware problem. Run some further hardware checks.

• 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). 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 http://www.sevenforums.com/tutorials/100352-hardware-stress-test-prime95.html 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. :warn: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.

I tested temperatures with real temp, and CPU has got around 90 degrees when is about 20% load, both cores...when I was loading it with 100% the temperature was increasing, so I rather stopped. this is to high, right? I read something about cleaning fan and area around CPU, that this might be a problem of overheating...computer is 4 years old and it was never opened and cleaned. But I checked some tutorials and saw, that I need to disassemble almost all computer to get to the fan and clean it? Is that correct? Is that really necessary for hp 6820s?

Thanks!

Yes, you will want to blow out dust. Dust can cause components in your system to melt if it builds up too much over time!! You may also want to re-apply the thermal paste for your CPU: Thermal Paste and How To Use It | techPowerUp Sorry about that; did not realize this was a notebook PC. You do not need to take it apart completely to clean out the dust. Just remove the panels that are easy to remove.


Removing Dust from the System:

Dust Removal:

To remove dust, follow the subsequent general procedure. If you have a desktop bought from Dell, HP, Sony, Lenovo, etc. make sure removing the desktop casing will not void your warranty first. Call the company if you are still under warranty and ask if it is okay to remove the casing and blow dust out. The procedure described is fine for laptops; just make sure no stickers are on panels saying if you remove the panel it will void the warranty.

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. Remove the casing for a desktop, or remove any screwed on panels and disc drives for laptops.
5. Blow out the dust inside by using a can of compressed air or a low pressure compressor. You will want to put the computer on a desk or table so you can maintain the can in an upright position if using a can of air. Blow into all crevices on the motherboard, heat sinks, cards, modules, etc. for a desktop. Blow into vents, opened panels, disc drive areas, USB ports, and the keyboard if it is a laptop. You may also want to blow inside the disc drive by replacing the drive to the laptop, starting the computer, opening the drive, and then turning off the computer and removing all power as described above including the 30 second power button step. For a desktop, you may also want to blow inside the disc drive by starting the computer, opening the drive, and then turning off the computer and removing all power as described above including the 30 second power button step.
6. Replace casing for the desktop. Replace panels and disc drive (if you have not already done so) for the laptop.
7. Plug power supplies in. AC adapter for the desktop. Battery and then AC Adapter for the laptop.
8. Start the computer and see if performance is better.

Easier Laptop steps:

1. Get a can of compressed air...
2. Shut down and turn off your system...
3. Unplug the system from any docking stations...
4. Remove the AC Adapter and then remove the battery...
5. Hold down the power button for 30 seconds to ensure all power is drained from the components. This closes the circuit and allows any remaining power to dissipate; it also clears the temporary memory of corruption and resets hardware/software connections. No permanent changes are made to the system doing this step...
6. Use the can of compressed air to blow into every vent, crevice, keyboard key, USB port, VGA/monitor port, etc...
7. Replace the battery and then plug in the AC Adapter...
8. Replace the docking station...
9. See how the system runs after doing all these steps...

   Warning

:warn:WARNING: Never use a vacuum cleaner or hair drier to clean dust out of your system!!

 

[anze87]

OK thx, I will try to clean it. One more thing...is it necessary to remove hard drive, RAMs and other components that are on the bottom side, to remove bottom panel? I think if I could remove bottom panel, it would be the easiest way to clean around the fan...

 

[writhziden]

I am not familiar with how your laptop is assembled. Often, if you remove all screws on the bottom, you can get to the fan. That would require removing all the components you mentioned first and also your CD/DVD/Blu-Ray drive.

 

[anze87]

I cleaned fan and I think that the problem is solved now. Temperature of CPU is now around 50 C. I ran MemTest86 for five passes and had no errors. So maybe was this bluescreen because of overheating...I will report if there will be problems again..

Thank you very much for helping me!

 

[anze87]

I thought that problem with BSOD is solved, but I got blue screen again today. I thought that is was because of overheating, but obviously it's something else...

Memtest86 showed no errors after five passes, CPU has got around 50 C. What now to do?

 

[writhziden]

Please provide us with your crash reports through the http://www.sevenforums.com/crashes-debugging/96879-blue-screen-death-bsod-posting-instructions.html.

Now that the overheating issue is removed from the symptoms, we may track down the culprit by analyzing those reports.

 

[anze87]

OK, here is new report. I read something about missing drivers, but I installed DriverEasy amonth ago, and thought that this program did install and update drivers...

System Age:

Različica/datum BIOS-a	Hewlett-Packard 68MDD Ver. F.09, 11.1.2008

Due to the age of your system, I would suggest checking the hardware compatibility with Windows 7: Windows 7 Compatibility: Software Programs & Hardware Devices: Find Updates, Drivers, & Downloads -> Download and run the Windows 7 Upgrade Advisor.​

• We do not recommend automated driver update software. It often finds drivers for devices similar to but not exactly the same as the hardware actually on the system. This can lead to conflicts and blue screen crashes. If you need help finding driver updates for a certain device, please start a thread in Drivers - Windows 7 Forums instead of using software. Driver updates are not always necessary and some updates can actually decrease system stability rather than increase it, so it is usually better not to update unless a device or its driver is causing problems with the system. If it ain't broke, don't fix it.
  
  
• McAfee Security Scan Plus may conflict with your realtime antivirus software. It also uses system resources and reduces system performance. Take a look at http://www.sevenforums.com/system-s...-system-security-combination.html#post1732627 for better options.
  
  
• Many of us on the forums actually do not recommend automated optimization tools for Windows 7. Windows 7 does a much better job of handling its own optimization than its predecessors did. We especially do not recommend registry cleaning as an "optimization" step because automated registry cleaning causes more harm to the registry than it actually repairs.
  
  In the future, if you need help optimizing Windows 7, please post a thread in Performance & Maintenance - Windows 7 Forums or follow the tutorial enclosed in that forum to http://www.sevenforums.com/tutorial...ws-7-a.html?filter[2]=Performance Maintenance.

  Analysis:
  My assessment is that your Windows installation has been damaged due to the driver updating and registry cure software. http://www.sevenforums.com/tutorials/219487-clean-reinstall-factory-oem-windows-7-a.html#post1839164​
