Turned on my computer and Norton antivirus update showed up. Haven't used Norton in quite a while but did in the past. Hit cancel and went to control panel to remove software. Removed Live update. Got error message "problem due to recent hardwar/software issues.Computer restarts itself every 5 to 15 minites continually. Went to recycle bin and restored symantec. Still restarting. Went to restore points after booting up in "last known good configuration". Restore points only let me go back in month of July, no earlier. After 8 attempts restore point on July 10th was successful, however computer still just flashes blue screen error message for a split second before restarting itself after 2 to 3 minutes each time. Can't get to a point where I can do anything. Please help.
