I have XPhome, Athlon 2600 and ample memory and storage. Some programs open and run ok. Some programs open but stick on an option. Add and delete programs sticks immediately after opening. Search can work but can also can stick randomly. I can start up okay but I have to close down using the power switch. I am running Norton Internet security constantly and it is continually updated and shows no indication of a virus. I seem to be okay on the net. I am reasonably competent but not very clever at computers.
