when i run avg free scan, the scan results ask me change shell32.dll, user32.dll, ntoskrnl.exe.. Is the problem serious? If so how do i change file? Also when working my laptop stops all of a sudden and a blue screen flashes which says that the software/ hardware u have installed is causing problem. when i restart the computer it says that the computer has recovered from a serious error. what do i do?? plz help!!!!

This has started a couple of days back.. The computer usually freezes when the blue screen appears and i have to restart. It asks me contact the DELL adminstrator(laptop is DELL) saying that a new software/hardware is causing this problem. It does say something like "releasing memory".No it does not happen in safe mode.

I had installed 3g player that day when the first time the problem occured but i UNINSTALLED it that day itself. But still that problem is persisting I am using WINDOWS XP. What is system RESTORE.. Is it safe? Would i lose any data?AVG isn't asking you to change those files. It's telling you that they've changed. This is normal, by the way. It's nothing to worry about.

As for your problem...
What OS is this?
How long have you had this problem?
What are you doing when it happens? Any specific programs?
Can you give us the exact message?
Does it still happen in Safe Mode?(1) Changed files...

It's OK. It's a good sign.

The changed files are normal. It happens when you update CERTAIN parts of Windows and when the system repairs files.

You receive a "System Has Recovered from a Serious Error" message after every restart

If Windows XP restarts because of a serious error, the Windows Error Reporting tool prompts you to report the problem to Microsoft for troubleshooting purposes. Windows may prompt you to report this information every time that you restart the computer, even if no error occurred during the previous session. After this problem begins to occur, you are prompted to send the information after every restart, even if you do not send the information.

WORKAROUND

You can solve this problem by recreating the pagefile. To re-create the pagefile, follow these steps:

1.Click Start.
2.Right-click My Computer.
3.Click Properties.
4.On the Advanced tab, in the Performance section, click Settings.
5.In the Virtual Memory section, click Change.
6.For Paging file size for selected drive, click No Paging File, and then click Set.
7.Click YES after the following warning appears:

If the paging file on volume X: has an initial size of less than xx megabytes, then the system may not be able to create a debugging information file if a STOP error occurs. Continue ANYWAY?

(X is the drive letter and xx is the amount of RAM installed on your computer minus 1 megabyte.)

8.Click System Managed Size.
9.Click OK four times, and then restart the computer when you are prompted.

Does it still happen in Safe Mode?

Have you installed any new programs in the past few days? If so, which one(s)?
Does the problem happen when you try using one of these new programs? Or is it random?
We still don't know what your OS is... If XP, have you tried System Restore?
