Random BSOD with Different Errors

Hi there.

I got a new laptop around 3 weeks ago and initially everything is fine.
Then 2 day ago I had a BSOD with 0x0000003B error with and today I had a BSOD with 0x00000050 error.
They occurred randomly.
I have not installed anything new that day.
I also have scanned my laptop with SUPERAntiSpyware and Malwarebytes after the 1st BSOD.
I have attached the SF file which I believe you need.

Thanks for your time.

Hi zacardo.

Install Service pack 1 and all other windows updates. Otherwise the system will remain vulnerable to threats.
Windows 7 Kernel Version 7600 MP (4 procs) Free x64
Product: WinNt, suite: TerminalServer SingleUserTS
Built by: 7600.16385.amd64fre.win7_rtm.090713-1255
Learn how to install Windows 7 Service Pack 1 (SP1)
Service Pack Center - Microsoft Windows

Daemon Tools, Alcohol 120% and Power Archiver Pro uses SCSI Pass Through Direct (SPTD), which is a well known BSOD causer. Uninstall Daemon Tools at first. Then download SPTD standalone installer from, and execute the downloaded file as guided below :
  • Double click to open it.
  • Click this button only:
  • If it is grayed out, as in the picture, there is no more SPTD in your system, and you just close the window.
Your crash dumps are not showing any finite probable cause.

Test your RAM modules for possible errors.
How to Test and Diagnose RAM Issues with Memtest86+
Run memtest for at least 8 passes, preferably overnight.

If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.

If memtest results free from errors, enable Driver Verifier to monitor the drivers.
Driver Verifier - Enable and Disable
Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.

information   Information
Why Driver Verifier:
It puts a stress on the drivers, ans so it makes the unstable drivers crash. Hopefully the driver that crashes is recorded in the memory dump.

How Can we know that DV is enabled:
It will make the system bit of slow, laggy.

warning   Warning
Before enabling DV, make it sure that you have earlier System restore points made in your computer. You can check it easily by using CCleaner looking at Tools > System Restore.

If there is no points, make a System Restore Point manually before enabling DV.

Tip   Tip

Let us know the results, with the subsequent crash dumps, if any. Post it following the Blue Screen of Death (BSOD) Posting Instructions.

Hi Arc.
Thank you for your promptly response.

Actually I have run Drive Verifier before I read your response.
Initially nothing happen.
But today when I start my laptop I get another BSOD with 0x000000A error.
I hard shut down my laptop than restart it, then I got the same BSOD with same 0x000000A error.
After that I boot into safe mode and disable DV.
Afterwards I can boot into windows normally without any problem.
The funny thing is I did not get any new dmp file even tough I get 2 new BSODs.
Therefore I do not attach new SFDT zip file, but I will upload it if that make any different to you.
As for your suggestions, so far I have done the DV test (before I read your response) and I have uninstalled the daemon tools.
For the record I uninstall daemon tools after the new BSODs occured.
I will continue to do your other suggestions.

Another BSOD just happen.
I attach the SFDT below.

From the latest zip you have uploaded:
OS Name    Microsoft Windows 7 Ultimate
Version    6.1.7600 Build 7600
So service pack I is not installed.
And ......
So the Driver Verifier is not properly applied, too. Follow the guidance I supplied in my earlier post about it.

And, let us know only after the suggested steps are taken. Otherwise there will be possibility that the same issue will recur.

Yes, I have not find the time to install SP1 and to do memtest.
But as I explain in previous post I have done the Drive Verifier test but I always get BSOD when booting windows.
And those BSODs did not leave any dump file, so now I have disabled the Drive Verifier.

Sorry for the late update.
I have done memtest with 12 passes and find 0 error.
Afterwards I update my Windows including installing SP1.
Since I update my Windows, BSOD never occurs.

Thank you very much for Arc for your suggestions.
