Hello there,

Go through this article
Windows Kernel event ID 41 error in Windows 7 or in Windows Server 2008 R2: “The system has rebooted without cleanly shutting down first”

Thanks for your reply. I followed the article and found that my problem was the Power supply, changed it and waited to see results. Todate everything works fine. I had a 480 watt PS and changed to a 750watt. I guess win 7 needs more power than xp.

Thanks a lot for your help. Sorry i replied a little late but I wanted to make sure that the new PS would solve my Problem Thanks again

No problem. Glad I could help
