The crash dump data are kinda odd.

Daemon Tools, Alcohol 120% and Power Archiver Pro uses SCSI Pass Through Direct (SPTD), which is a well known BSOD causer. Uninstall the program 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.
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.

The computer seems to be old. Is the computer hot? Report us the heat of the computer after a couple of hours of your normal usage. Upload a screenshot of the summery tab of Speccy.

SPTD was not installed on my computer

I did the RAM test overnight and there were 8 passes without any errors.

The temperatures are:
CPU - 44-47
MotherBoard - 45
Graphics card - 50
HDD - 1TB - 31
HDD - 640GB - 35

another BSOD occured. I uploaded the information.

I just wanted to tell you some more background information:
I had some BSODs for almost 2 weeks.
I had bought the 1TB HDD and then installed a new win7 ultimate on the 640GB HDD.
After that, the same BSODs still occured..
I hope this info is somewhat useful..
Thank you!

Your crash dumps are not showing any finite probable cause. In such a situation, it is better to 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.
