BSOD when performing computer search

It seems to have set it to 11 passes which is good, have you managed to obtain the log file for chkdsk? The same Stop 0x50 has occurred, it has a wide range of possible causes, and is caused when an invalid address is referenced, and the virtual address containing the data can't be paged into a physical memory address.

Code:

Usual causes:  Defective hardware (particularly memory - but not just RAM), Faulty system service, Antivirus,  Device driver, NTFS corruption, BIOS

Did the BSOD occur after removing or before removing AVG?

Last BSOD occurred after removing AVG

I couldn't see any problems, it's best to have a more thorough testing of the hard-drive to give a more reliable analysis:

Run some hard-drive diagnostics and follow these steps:

• Hard Drive Diagnostic Procedure

Find your hard-drive manufacturer and run their tests.

   Note

You may run the How to use SeaTools for Windows, as it may easier to execute and understand. Run the Basic Test for both Short and Long.

Additional Tests:

• SeaTools for DOS | Seagate
• CrystalDiskInfo - Software - Crystal Dew World

If you have an SSD, make sure the following are up to date:

• SSD firmware
• BIOS Version
• Chipset Drivers
• Hard disk controller drivers/SATA drivers
• If you have a Marvell IDE ATA/ATAPI device, make sure the drivers are up to date from the Intel site or Marvell site and not from your motherboard/vendor support site.

If you need more information about your system then:

Update your System Specifications with Speccy, and then copy this information into your System Specifications: Go to your UserCP, and then select Edit System Spec in the left pane. Copy the information from Speccy into the required fields. These System Specifications will then follow your every post.

If you need the model number of your hard-drive, then it will be the long number after the brand of the hard-drive (see my system specifications as an example).

I've ran
1. CrystalDiskInfo
2. Western Digital Data LifeGuard Diagnostics - both quick & extended test passed succesfuly

Good to know, and it seems your system doesn't even meet the requirements to run a 64-bit version of Windows, you only have 1GB of RAM, whereas, the required amount is 2GB of RAM.

Your BIOS is also a little dated too:

Code:

BiosReleaseDate = 09/05/2011

These are only two motherboards I could find matching the motherboard model provided:

• MSI UK ? Search

Update the BIOS with the exact model of your motherboard.

Code:

SystemManufacturer = MSI
SystemProductName = MS-7680
SystemFamily = To be filled by O.E.M.
SystemVersion = 2.0
SystemSKU = To be filled by O.E.M.
BaseBoardManufacturer = MSI
BaseBoardProduct = H61M-E23 (MS-7680)
BaseBoardVersion = 2.0

Finally, I've re-installed Windows 7, which solved the issue.
Thank you for your help !
