I rebooted my computer this afternoon, and it reboots enough to show my online connection, but nothing else on my boot screen. When I click on any program or shortcut I get "Windows cannot access the specified device, path, or file. You many not have the appropriate permissions to access the item." The only way I can access my browser is by going to the control panel and clicking on windows update. I noticed in one of my attempts to get everything to boot, that the date was saying 4/4/2010, but I went in boot with c prompt (or whatever it's called) and did manage to change the date to the 1/1/2010, but that didn't fix the problem at all. I cannot access system restore, I get the message above. I look at the control panel, but cannot click on anything without the above error message. I can access my files and documents, and look at the thumbnails, but I cannot actually open any of the files. Is there any way this can be corrected without having to call in a pro? Is there something I can type into the DOS commands on the recovery panel or something. The computer is about 5 years old, and it's running windows XP with sevice pack 2.
