After upgrading the CPU windows 7 does not boot

[Mojo-Jo-Jo]

I have a computer at my home and recently I have upgraded my CPU. I am running windows 7 on my computer. Now the problem I am facing is that, my system does not boot up. It hangs with a black screen griping about a signature file. It gives me the message saying that the “hardware or software change might have installed a file that is signed incorrectly”. Is there anyone who is facing the same problem or has some idea related with this problem? Even if you some knowledge related with it, then please help. Thanks.

I have solution for this problem. I have tried this solution for fixing my problem and it had worked in my case. If you have the Windows installation disc with you, then try to insert the disc in your machine and after restart the machine. There you will require clicking on "Repair your computer,” After doing this you have to choose the recovery tool. The rest will be done by your computer. So try out this fix as it might help you as well. Hope have helped you.
