BSOD-computer crashes all the time

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

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

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...

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.

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! :)

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?

Please provide us with your crash reports through the https://www.sevenforums.com/crashes-d...tructions.html.

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

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:

Code:

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.

Device Concerns:

It appears the wrong drivers may be installed for your BlueTooth devices. Please uninstall all BlueTooth devices through Device Manager -> Start Menu -> Right click Computer -> Manage -> Device Manager from the list on the left.

Device Manager : Hidden Devices may also help.

Software Concerns:

Code:

Start Menu\Programs\DriverEasy
Start Menu\Programs\McAfee Security Scan Plus
Start Menu\Programs\ParetoLogic\RegCure Pro

[list][*]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 Good and Free system security combination. 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 Optimize Windows 7.

Analysis:

My assessment is that your Windows installation has been damaged due to the driver updating and registry cure software. Clean Reinstall - Factory OEM Windows 7
