Problem in the launch of the service apache

[rems]

Hello, I installed XAMPP and used it so far without problem. For some days, in the launch of the service apache, Windows (XP Pro - authentic) meets systematically an error (Exception privileged Instruction - 0x0000096 occurred in the application in the place 0x6ff2e0d4). I did not find answer on Internet. To note that the reported codes are always the sames. A Web server turns on my post : I have to solve this problem quickly. Thank you for your help.
