I'm suddenly having the EXACT problem described on the below Microsoft page.
However the download/patch on that page is ONLY for SP1.
I have SP2
Here's the page, but I've pasted the detailed info below...
Microsoft has released a patch that addresses the "System has recovered from a serious error" issue in Windows XP, and is discussed in Knowledge Base Article 317277. Download now to prevent this message from occurring each time the machine boots.
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 begin prompting you to report this information every time 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 choose not to send the information.
This problem occurs because after a Minidump (or memory dump) file is written, the paging file continues to have a flag set that indicates that a memory dump file needs to be written.
To resolve this problem, download this file.
Any ideas about what to do about this? I've seen other posts on here that are similar but none seem to detail exactly the issue I'm having...which is perfectly described my Microsoft themselves.
