Vista 64 missing


Captured By Tree

I have HP Pavilion with Vista 64. I opened my laptop last week and I don't know what happened. It stopped opening all files, my friend used my jump drive to repair the excute file, so now I can at least open files, but my laptop says I have no disc drive, it won't let me on the internet to download, it also says that my Symantec Service Framework stopped working. My back up is gone. It won't let use the recovery system. I am at wits end and have tried downloading regtool, but it won't work on 64 bit, have been going through forums but none of the solutionns apply to the numerous problems, any help is greatly appreciated.

Thank you,
