Some days ago I have a problem with a W2K Advanced (virtualized with VMWare 1.04): BSOD with IRQL error, but in safe mode windows boots fine. Several days trying to find a solution but nothing. A college suggested to use this utility: http://www.spamignorer.com/bsrecover/bsrecover.exe And it worked! I can boot in normal mode again. (it is supposed that it only works if you can boot in safe mode) Someone has told me that the utility can do spam. I have been sniffing the activity of the network but nothing. Antivius with heuristic and nothing. Changes to the registry and nothing. What do you think? My Windows seems fine (and booted fine after this program did some magic), sould I be worried?
