Thank you so much, looks like the PC is health and virus free. I appreciate all of your help. Now I just need to solve the reboot and lock up problem. Many thanks!! You can close this topic, I would imagine for operating system help, the help with the lock up and restart would go in a different forum? If not, is there a utility I can install and run in the back ground that will log what error occurred when a reboot or lock up happens? Maybe see if there is a driver that's malfunctioning or so on?
Some process is using too much memory which is causing the freezing. Using your task manager to monitor which process is using too much memory.
