I TRY TO CLOSE OUT OF A WINDOWS PROGRAM. INSTEAD OF DISAPPEARING I GET AN ANNOYING BOX. ABOUT BLANK. PAGE EMPTY BUT THE TITLE IS ABOUT BLANK.

My computer started showing some problems like "could not read memory from"—– something it shows blue caption with white words saying win xp has stopped working due to some problem. Sometimes it does not boot properly close and starts many times. I tried to repair it with windows cd but few files were not copied saying these are corrupt. I formatted it and and installed fresh xp then I went to Microsoft site to updated. After downloading few files it restarted and again behaving as it was doing before I installed new Xp. My earlier xp installation worked for 9 months. Please help what to do. How to solve this. Is there free software that can repair Xp? What are the indications if RAM is not working properly

have see this in my browser all night but because my computer has been so slow and shutting down tonight I never checked it until now and it’s saying that it’s spyware or adware and that I need to install a program to remove it. I really don’t know what I;m doing, i bought the computer, brought it home hooked it up and now i know some but not a lot. do i need to install something to have it removed and if i do can i do it safely and free? thank you so much.

I’m looking for an all-in-one software for windows vista repair.
