Last week my wife came and told me that her computer just started down loading an up date and was rebooting. She wasn't on the net. A HALF hour later it was still loading the up date on the reboot screen. After a half hour it was still loading. It said STEP 3 of 3 0 % compleat. Don't turn off computer. A half hour later I turned off the computer and restarted it. It did the same thing. I shut it down once more and started in safe mode, that was the only way to get to files I wonted to save. No luck, it wouldn't let me save any thing to disk. It said that I didn't have the file to run the DVD player. I rebooted the computer and it came up in part safe mode. It didn't say safe mode it just looked like it and nothing would work. No internet, no USB and no DVD. I tried restarting several times, same thing. I got my Son on the phone and he said that it was a viruses that had corrupted some files and that I would have to do a clean install of the OS. I did that and every thing is fine. Can any one tell me if this was a viruses or did I do this by shutting down the computer when I was told not to. On the reinstall of the OS (Vista) I had to down load the up dates and they only took about five or so minutes on the reboot and that was 250 MB of stuff. If it was a viruses it went from working to not working in one hour.There is no way we can just tell a virus by symptoms alone. Thats why we always request logs. No logs, no telling...I understand. I don't know how I could have GOTTEN any logs. I guess that it was best that I just reloaded the OS. Thank you for your time.
