Need help with BSOD

I got a new laptop Sony VGN-AW420D about a week ago with no problems at start up until a couple of days ago when there's a blue screen crash. I copied the minidump file to see if anyone can help out in here.

Many thanks in advance for any help.

Windows is running on 64bit if that is useful at all.

you said that you just bought your computer a week ago. What software have you installed on your system? Are you using any third party anti-virus software?

Regard,
Tuan

Hi,

I find your situation interesting - the reason is both your BSODs are practically identical.

Code:

 BugCheck 51, {1, fffff8a000024010, e43000, 374}
 Probably caused by : ntkrnlmp.exe ( nt! ?? ::NNGAKEGL::`string'+9b7a )
 ииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииии
 BugCheck 51, {1, fffff8a000024010, e43000, 374}
 Probably caused by : ntkrnlmp.exe ( nt! ?? ::NNGAKEGL::`string'+9b7a )
 ииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииии
 
AND they both occured approximately 1hr 30mins after you started your PC up.

Code:

 System Uptime: 0 days 0:01:27.876
 System Uptime: 0 days 0:01:25.268
 
Ok, so the probable causes on this one are File system corruption, Malware or Hardware.

So, run chkdsk /r from an elevated (run as admin) command prompt.

Then download and run Malwarebytes: Malwarebytes' Anti-Malware: Malwarebytes

If they both check out ok.. then we will have to look at hardware.

there is a Norton Internet security trial version that comes with the laptop. I uninstalled it and did not have any anti virus software installed. All softwares installed are itunes, skype and firefox, with java and a couple of windows updates. everything else is in factory condition.

re reventon: i believe they mean 1 min and 27 seconds because it only happens at start up.

Oops - misread that!

In that case - type msconfig in the start menu -> enter -> go to the Boot tab and check the boxes beside Boot Log and Make all boot settings permanent.

Then - immediately after you restart from a BSOD go to C:\bootlog.txt and copy the contents into your next post (remember to use a code box - BBcode: [code][/code])

Also still try the chkdsk and the Malwarebytes scan that I mentioned earlier.

I would not advice you to connect to the internet without anti-virus protection. I recommend the free Microsoft Security Essentials.

Also, I found an older driver in your latest dmp file Windows 7 does not play well with many older drivers.

SFEP.sys Aug 03 2007 - Sony Firmware Extension Parser driver for VAIO. Recommend you update this driver.
