I have what seems to be the same issue. Unfortunately, I believe there is a problem with the machine, and this message is not just for "Information". The problem is that the computer runs fine for a couple of weeks, then when I boot the computer, Windows will not load and display "The file c:\windows\system32 is missing or invalid". I need to restore the registry and then it works again for a couple of weeks. I'm running a AMD Duron 1200 on a VIA-KT133 chipset (I'm not 100% sure about the KT-133, but it's definitely a VIA). Unfortunately, the machine is at home, and I'm at work. On every boot, I'm getting 4 instances of "Application Popup" Machine Check logs in my event viewer. Only 1 of the 4 has "Machine Check: Regs", the other 3 are just "Machine Check". This is on a clean install of WindowsXP with Service Pack 1. No changes to the system have been made since the OS install (no other software has been installed either). These are the only "problems" that show up in the event viewer. Every other event is normal. The strange thing is that if I run a chkdsk /f, the very next boot doesn't show the Machine Check in the event viewer. It then shows up on the following boot and every subsequent boot. I've disconnected all hardware (pci cards, drives, etc..) except for the HD, ram, and processor. I've switched out the video card and still get the same errors. I've ran memtest on the ram and it is okay. Tonight, I'll be running diagnostics on the HD to verify the HD is 100% okay. The point of this post is to say that I think, although it might have not manifested itself, that the "Machine Check: Regs" information in the event viewer may be because of a critical error somewhere. I can't find much helpful information anywhere else. Also, I'm going to try to disable write behind caching on the HD. I've read that the Machine Check message may display when the system powers off before windows is done writing to disk on shut down. Anyway, if anyone has an idea why I get the "The file c:\windows\system32 is missing or invalid" after a couple of weeks on my machine, I'd appreciate any ideas. I figured that if I fix the "Machine Check: Regs" problem, that I will not get the system32 missing or invalid error.
