Windows 7: Recent Spate of Random BSODs - Error Code 0x0000004a in ntoskrnl.exe

Recent Spate of Random BSODs - Error Code 0x0000004a in ntoskrnl.exe

7 year-old Sony Vaio VGN-FW21L runnung Windows 7HP (64-bit) SP1

Has 4Gb RAM and 720Gb WD Black HDD (7500BPKT)

Everything has been running smoothly until the last few weeks - basically since 4th Sept this year when I have been getting random BSODs (10 in total since then).

I'm not doing anything processor/memory intensive (like playing games) and i have returned to the PC on several occasions to find the message that the computer has recovered from an unexpected shutdown.

Looking at the minidump logs - they are all IRQL_GT-Zero errors (error codes are all 0x0000004a in ntoskrnl.exe and, with the exception of two earlier BSODs (on 31/May/15 and 05/Aug/15) they all have the same crash address: ntoskrnl.exe+735c0.

Am I looking at a likely RAM problem here?

I thought at first it might be a HDD/pagefile issue.

The laptop vents and fan was cleaned of lint around a year ago when I replaced the power button and the CPU was re-seated and fresh thermal compound applied.

I have a system monitor which is reporting that currently the CPU is running at 48C and the HDD at 40C

Any help/suggestions gratefully appreciated.

Is this likely to be a RAM issue or HDD or CPU or cooling?

Hope this helps,

 DRIVER VERIFIER

warning   Warning
Please make a backup of your important files and get your rescue media or create one.
Please create a restore point.

Please follow this tutorial to run driver verifier.

Driver verifier stresses your drivers and will crash your pc if any driver fails due to a violation.

Driver verifier should be performed for a max of 48 hours, or when you have a bluescreen, whatever comes first.

If driver verifier has found a violation and you can't get back into windows normally, try to boot into safe mode and reset in safe mode driver verifier, or in the troubleshooting options open command prompt and type verifier /reset.

Note   Note
Your system will act very sluggishly while driver verifier is enabled, this is normal as your drivers will be being subjected to heavy testing in order to make them crash.

Ok - I'll look at that. In the meantime, I've downloaded Memtest86+ ver 5.01 from Memtest86+ - Advanced Memory Diagnostic Tool and will also run that to see if it is a memory problem.

Thanks for your help so far.

Will report back later...(possibly MUCH later )

You'll have to run MemTest86+ for at least 8 passes, less isn't worth it as the results are not conclusive

MemTest86+ needs to be run for at least 8 passes for conclusive results. Set it running before you go to bed and leave it overnight. We're looking for zero errors here. Even a single error will indicate RAM failure.

Hi ZaphodB,

I have digged through the internet about this error, because I want to know more about it, and I came across a few sites where users are having problems similar to yours.

There is only 1 thing common with the crashes, the process name
It appears to be Bitdefender's main active protection process.
Although I always thought it was a process from Windows.

As a test please uninstall Bitdefender using the uninstall tool you can find here and use Microsoft Security Essentials as alternative
Code:

Thanks axe.

Currently running MemTest86+ Test has been going for over two hours now and hasn't found anything yet but I know it is early days. Will leave it running 'till the test ends and then report back.

Interesting find on the BitDefender scene. I've d/loaded the removal tool for my specific product on another PC and that's ready to go when the RAM test ends.

BitDefender is also causing a problem on a different machine. When that PC boots up, the firewall is ON (enabled) and I can't print to any of my WiFi printers. This is despite turning it off in the last session. If I then turn the firewall off, I can then print to all of my WiFi printers. On a different PC running BitDefender, the firewall is ON and I can print to any of the WiFi printers. Both PCs are running Win 7 Home Premium SP1 64-bit. Strange eh?

Will post updates to this thread as and when I have any.

Kind regards

Zaph

I had the same thing at my internship.
It was due to a setting in the adapters, the stealth-modus was set to remote and had to change it to off.
