Windows 7: BSOD after user login, Error 0x50 and 0x51

BSOD after user login, Error 0x50 and 0x51

I was having some issues with the sound on my laptop today. So restarted it. Upon restart I can login, then when my desktop appears and while it is loading I always get a blue screen of death with the above errors. I have acess to safe mode and have already tried a limited startup, disabling my sound drivers and un-installing my antivirus.

SF diagnostic tool log attached.

Any help would be much appreciated.

Hello dhendy91.

Install Service pack 1 and other windows updates; otherwise it will remain vulnerable to security and other threats.
Code:
Windows 7 Kernel Version 7600 MP (4 procs) Free x64
Product: WinNt, suite: TerminalServer SingleUserTS Personal
Built by: 7600.17207.amd64fre.win7_gdr.130104-1435
Learn how to install Windows 7 Service Pack 1 (SP1)
Service Pack Center - Microsoft Windows

Free up the startup. They are not necessary at all, but causes various problems including BSODs.
  1. Click on the Start button
  2. Type “msconfig (without quotes), click the resulting link. It will open the System Configuration window.
  3. Select the “Startup” tab.
  4. Deselect all items other than the antivirus and the touchpad driver, SynTPenh.
  5. Apply > OK
  6. Accept then restart.
The Stop 0x50 BSODs are pointing to AVG IDS Application Activity Monitor Driver.
Code:
fffff880`068f3928  fffff880`043c5938Unable to load image \SystemRoot\system32\DRIVERS\avgidsdrivera.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for avgidsdrivera.sys
*** ERROR: Module load completed but symbols could not be loaded for avgidsdrivera.sys
 avgidsdrivera+0x1f938
Description here: Driver Reference Table - avgidsdrivera.sys

AVG is not efficient enough to give you proper protection (coming to this point a bit later); morever, it is causing BSODs here. Better you uninstall it. Uninstall AVG using AVG Remover. Use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.
Download, install and update those, and then run full system scans with both of them, one by one.

Most of your crashes are stop 0x50. And they are silent about any probable cause.

Use !analyze -v to get detailed debugging information.

BugCheck 51, {1, fffff8a000023420, feb000, 374}

Probably caused by : ntkrnlmp.exe ( nt! ?? ::NNGAKEGL::`string'+997a )

Followup: MachineOwner
---------
According to Carrona.org, STOP 0x00000051: REGISTRY_ERROR
Usual causes: Hardware failure, File system corruption, Security issues

As the antivirus is failing here, we should be more cautious about the security issue. Scan the system for possible virus infection.
Check for any file system corruption.
Run SFC /SCANNOW Command - System File Checker

Finally, the BIOS is old.
Code:
BiosVersion = V1.15
BiosReleaseDate = 09/13/2010
You may update to Version 1.23, dated 2011/05/23 from Support Download (EasyNote TM99 notebook)

If all those fail (may not, I guess), will search for hardware issues.

Let us know the results when done.
