I have an Asus x55u laptop. This laptop is running Windows 7 Ultimate on a 500GB hard drive. I put the system to sleep last night. This morning, I tried to wake the system only to find a unlit screen. I held down the power button and shut the system off and restarted. Windows would not start! After restarting a few times, Windows started without a problem. After logging on, the system seemed fine until I tried to delete a folder. The folder was somehow read-only? I right-clicked on it and and clicked properties. Read-only was checked. I unchecked it and a window popped up "Acess is denied". Yes, I'm the administrator. I've used this same account for 3 years with no issues. I checked other folders and files. Everything is read-only! After several restarts to no avail, I tried to uninstall a program. The installer told me that "Acess is denied". The system is not affected as I checked everything! The hard drive is reading slower than usual. I've had two files vanish on the desktop already. I'm now preparing for the worst. Update: Now the backup is only going at 4MBS. Another file has vanished. Still backing up. Update 2: This is very strange. After I backed up files from my laptop and onto a desktop running Windows 7, now that desktop is showing everything as read-only! Either the files are badly corrupted or there is a virus spreading within my files. Avast Anti Virus has not detected anything on either computers. I'm freaked out right now. Now both computers are running like crap.
