waiting for ur replies..

Try replacing your memory, then if you can, test your hard drive for errors. If you can't do this by yourself, take it to a computer repair shop or to a computer savvy friend

hi Tmagic650.. i appreciate ur help ,, but it din't work.. i checked the ram and the hard disk... no ram problem or harddisk error ! .. my laptop is normal otherwise.. this blue screen error comes like once in 2 days or so.. when i reset my laptop.. its back to normal.. any other help please.!!! :-(

Someone else had the same error reported on this thread: http://www.techspot.com/vb/showthread.php?p=585185&highlight=ipnat#post585185
Please take a look and see if that resolves your issue as well

i have downloaded and installed the windows debugging software.. but how to get those mini dump files???

Read: All about Minidumps and analyzing them

Hint: They are located in Start->Run-> %windir%\Minidump folder (just copy and paste that into run)

thanks kimsland.. i dint find any files in tht mini dump folder.. okz let me read the link u provided..!

ok

But it's probably disabled in System in Control Panel
And then under dvanced Tab
Then under Startup and Recovery

It is not disabled there!
but my system restore is turned off.. should i on it?

actually when the blue screen error happens.. my laptop stops responding , then i press n keep the power button to force shut down.. and then reboot it again.. could this be the cause that there is no mini dump files in the folder?

It is possible to get no Minidump, due to System lockup
Also System Restore off is your choice (mines off)

Try this:

Manual steps to run Chkdsk from My Computer or Windows Explorer

• Open My Computer, and then right-click the hard disk that you want to check.
• Click Properties, and then click Tools.
• Under Error-checking, click Check Now. A dialog box that shows the Check disk options is displayed

Use one of the following procedures:

• • To run Chkdsk in read-only mode, click Start.
• • (tick) To repair errors without scanning the volume for bad sectors, select the Automatically fix file system errors check box.
• • To repair errors, locate bad sectors, and recover readable information, select the Scan for and attempt recovery of bad sectors check box.

Note If one or more of the files on the hard disk are open, you will receive the following message:

Click Yes to schedule the disk check, and then restart your computer to start the disk check.

Wait until Chkdsk finishes Checking / Repairing any faults
Windows will then either restart your computer or continue loading Normally.

thanks.. let me try it..! ^_^

i have checked my C: drive by the window's disk check utility..with both the disk check options ticked.. still nothing visible in mini dump folder.. i guess i have to wait till the error happens next time..!
another question is.. why din't my laptop restart even though automatically restart option is ticked in System failure options of Startup and Recovery after the error happened..? Can u guess out something from the image i have uploaded in my 1st post?

The screen dump says it got locked up on a faulty driver
Can be CMOS settings
Can be Drivers, including Video Card
Can be Ram faulting at a driver
Can be programs such as Norton, or ZoneAlarm or Virtual software (by the way, if you have those, remove them)

i donot have any virtual softwares installed.. as antivirus i use NOD32.. by the way i keep my windows auto update OFF / firewall & virus protection ON in Windows Security Center..
this is a new laptop.. n i am really tensed by that error..! :-(

Lets try Turning Windows protection off

Start-Run-> Services.msc

Locate Windows firewall, double click on it, change it to Disabled (and stop it, but that doesn't matter) Apply->ok
Locate Security Center, double click on it, change it to Disabled (and stop it, but that doesn't matter) Apply->ok

Restart, and test

did as u said.. n restarted..! but what should i test now?.. still no files in minidump folder.. should i wait for the error to happen again? then may b there will b something in that mini dump folder..

Just wait and we'll see
By the way what firewall are you using again?

its windows xp's default firewall !

Oh

Ok if you haven't had any lock-ups, for a normal amount of time (that it use to lockup on)

Then turn on Windows firewall in Services

okay.. i turned on the Windows Firewall in services..!
