Windows Protection Error on restarts.

I had this error when I added new RAM to a Win95 computer. In my case I had a conflicting IRQ or I/O address for the NIC. Try disabling the network card in Device Manager and see if it boots. If it does, then uninstall and re-install the network card (or whatever device is causing the problem). For more information on this error, see Microsoft Support Article #Q149962 at this address: http://support.microsoft.com/support/kb/articles/Q149/9/62.asp

I hope this helps! :-)

I have run into the same problem and it ended up being a corrupted system file. specifically one of the network related files. (diagnosed because could boot to safe mode, but not safe mode with network support)
If you can boot to safe mode, then it is in one of the less critical files (such as network support - that would include dial up networking) try uninstalling that while in safe mode, if you can boot normally then you found the problem and can reinstall that feature.

I had the same problem. Managed to run a scandisk (i belive the drive was put in another working computer ) the scandisk found problems on the drive, fixed them and then the O/S booted fine.

I hope this helps

I had this problem on a Dell Optiplex GXa, Win 95. Had to boot to command prompt, copy a new 3com NIC file, el90x.sys, to the windows\system folder.

Came to this conclusion by booting into safe mode, disabeling devices one by one, rebooting aftereach item was disabled until I found the culprit. Also try checking the P/C mfg.'s web site for known issues.

Hope this Helps!
