I normally leave my computer(win 98) on 24 -7. I have security camera connected. When i come in in the morning my computer is sluggish and slow. I restart it and it works fine. On monday mornings after it running all weekend a blue screen comes up saying the memory is very low and will not run norton virus. I shut the computer and restart it and it works fine. I thought the DSL was causing it but I disconnected the DSL this weekend and it did the same thing
