Set for small memory dumps.

Please upload your msinfo32.nfo file. To get this: Start Menu -> Type msinfo32 into the Search programs and files box -> When it opens, go to File, Save -> Save as msinfo32.nfo and save in a place you will remember -> Let it finish the process of gathering and saving the system info -> Right click the .nfo file, click send to compressed (zipped) folder -> Upload the .zip file here.

Please upload your msinfo32.txt file.

Okay

Here it is

 

[koolkat77]

It's corrupt.
Can you get the text version?

 

[AK5000DK]

Here is the text file. I exported the information to notepad. My system is in Danish, i hope it doesnt matter.

I exported it to notepad. But the file size is 1,9mb. I have compressed it to reduce the size.

System Optimisers

Please remove the following software

Start Menu\Programs\Advanced SystemCare 6	Public:Start Menu\Programs\Advanced SystemCare 6	Public

This software is a known cause of BSOD's. The windows 7 operating system does not require these registry cleaning software. They often tune-down rather than tune-up and can wreck the OS beyond repair. Microsoft have improved Windows 7 significantly and it is much better at organising and optimising itself than its predecessors. Check this, this and this thread for evidence.

If you feel the need to use a registry cleaning or optimisation software, most of us recommend the use of CCleaner - PC Optimization and Cleaning - Free Download but make sure you back up the registry before making letting ccleaner delete anything.

Reduce items at start-up. Nothing except anti-virus is required:

• http://www.sevenforums.com/tutorial...ation-conflicts-performing-clean-startup.html

Perform a System File Check:

1. Click on the start rb:
2. Type CMD on Search
3. Left click and Run as Administrator
4. Type SFC /scannow

Disk Check on your hard drive for file system errors and bad sectors on it:

Let us know the results.

 

[AK5000DK]

Thanks for your replay.
I had this problem before I installed Advanced SystemCare 6. I actually installed it, to see if it can help me solve the problem. But I have removed it now, as you suggested.

I have just had one more error shutdown. I have attached the minidump file.

And now, i will do the steps you suggested, and report back

 

[koolkat77]

I'll check your dump and report back in a couple of hours.
Let me know the results.

 

[AK5000DK]

Disk check says no problems. I have done the other steps, but I dont know if it helped or not, because there is a few hours between each error reboot. I gues i just have to wait and see if they helped or not

Sounds good Koolkat, I look forward to hear from you

Hmm. It seems that ESET is causing the BSOD. Description here:
Driver Reference Table - epfw.sys

Can you uninstall for it for testing purpose?
Uninstallers (removal tools) for common antivirus software - ESET Knowledgebase

Use MSE for the time being.
Microsoft Security Essentials - Microsoft Windows
