[Junior48]

Sure, we can do our best, but our gonna have to give us alot more information.

When does it hang?
What type of hardware do you have?
How old is the computer?

[Junior48]

The computer is four years old Celeron(R) CPU 2.00GHz 1.99GHz 736 of Ram
When I am working everything just stops for a minute or so and I get the message that the particular programme is not responding then it will just start operating again.
One thing I have noticed also my screen saver runs really slow. Other than that the computer seems to run perfectly. Hope that is of some help.

OOPs it also takes quite some time to open programmes etc! Annoying thing like opening an attachment or a photo!!

Have you checked for spyware?

Have you ever defragged the harddrive?

Do you have an antivirus??
Did you do a full system check for viruses and the antivirus is up-to-date??
