Lately this error has been coming up everywere on my computer, at startup ill exit out of aol instant messanger and it will give me the error when i start up SBC Yahoo DSL sign in it gives me the error so im forced to use internet explorer, i get it on about 2/5. It used to happen to me with full spectrum warrior but then i would just restore my computer to an early point in the day and it would run fine, my computer seems like its falling apart!
I have 512mb RAM, i have tested each one individualy and tried to run the same programs but the same error message comes up. Ive tried memtest no luck. Can anyone help me fix this lame error.

Sorry if this a common topic but i searched and got no luck, but half my words were filtered (could, be).
