Archie, here's the OP's files if you couldn't open the .RAR file :)

Uninstall Daemon Tools Lite:

Code:

Start Menu\Programs\DAEMON Tools Lite

This program is well-known to cause BSODs in Windows 7.

Code:

SYSTEM_SERVICE_EXCEPTION (3b)

BugCheck 3B, {c0000005, fffff80002d9ab20, fffff88009558080, 0}

Probably caused by : ntkrnlmp.exe ( nt!ObDereferenceSecurityDescriptor+20 )

Code:

Usual causes:  System service, Device driver, graphics driver, memory

Memory:

• RAM - Test with Memtest86+

Run Memtest86+ for least 7-8 passes, and preferrly overnight as it can take a while to fully complete.

Test each RAM stick individually, if an error is found then move the same RAM stick into the next DIMM slot and test again, if errors are found for the same RAM stick in every available slot then you have a faulty RAM module. On the other hand, if no errors are found in the next slot or the other slots for the same RAM module, then you have a faulty DIMM slot.

Test each RAM stick and every motherboard DIMM slot available.

Run this program to check for missing and corrupted drivers:

• Driver Verifier - Enable and Disable

The drivers for your Ethernet Controller and your USB Controller are also missing; have you installed all the Important and Optional Windows Updates? Check for new updates also:

Start > Type: Windows Update > Check For Updates (left pane)/Install Updates

1.i've installed the missing drivers ( it wasn't an issue , i knew about them)
2.i'll try the memory test tonight ( i have 16 GB , all of the 4 slots are in use (4X4 ) )

Have you uninstalled Daemon Tools Lite?

yeah , just uninstalled deamon , updated my windows , and installed avg 2013 . seems fine , no crashes since then !
but what should i do if i need daemon tools? i've downloaded the trial version of daemon tools but its gonna end in 20 days , and the free version is the reason for bsod ... ( i can download cracked ver of full DT but i just dont need it )
any suggestions?

and thanks for everything up to now .

Your welcome, and Windows has it's own built-in versions for much of the features that Daemon Tools provides:

• Burn Disc Image - ISO or IMG file
• Virtual Hard Disk - Create and Attach VHD
