I have an dell inspiron 6400/E1505 And for some reason my PF continoualy climbs until my comp is locked up and I can to s*&^ until I do a hard shutdown. I have sat there and watched the processes but I cant seem to find anything that keeps using more and more memory. I had a virus approx 2 to 3 mo ago but I got rid of it and I have done every thing I can to try and find out what is causing it and how to fix it. Just so you know I am in Iraq and have very limited internet access and the access I do have is very slow. I appreciate your help.
