Hi, When i right click on desktop and go to properties for changing the desktop image, it hands up and shows a rundll 32 problem. I need to restart my system because it hangs up!! Any solution please.. thank you.. bobby

Hi Bobby, I don't have much experience yet with my XP but on my win98 I had a problem shutting down because "Rundll32 was running". I did a virus scan and found out I had a virus/worm Win32:CTX. I read where sometimes a virus will cause rundll32 to pop up and in my case, it did. Hope this helps. maggie

Windows XP comes with a very handy tool called the system file checker. The SFC tool itself will scan your computer for system files that may have been replaced when some old or poorly made program was installed. This usually happens because the programmer who made the software did not create it to check the versions of each system file it replaces. To protect your computer from old system files, Microsoft created a special service that is built into the operating system. This service monitors your system files, and if one is replaced or deleted, ICS will automatically restore the system file. SFC works in conjunction with a utility called Windows File Protection that keeps the system file cache: (%Systemroot%\System32\Dllcache) uppdated with the newest Microsoft Approved files as they are installed on your system. I prefer to use the system backup for the ability to roll back to a former configuration however. To manually invoke the system file checker, be sure you have administrative access then click start, run, and type: sfc /scannow The system will immediately begin to check all the current system files and restore the cached approved copies. You may be asked to insert the Windows CD as well during the restore.

i will try to work with the above answer, thank you.. still i expect any more suggestion from other experts..
