The memory could not be “read”

Hello everyone,
I need your help……
So, my problem is when I open windows on Windows XP or Internet sites or applications, after a while when I'm at work, I wander a message that says:
(The instruction at "0x1003fa55" uses memory address "0x08ab4aac." The memory could not be "read" So Click OK to terminate the program. Click Cancel to debug the program).
And all windows are closed. Please tell me, how to solve this problem, because it's starting to bother me much.
Thank you to all.
