Hi Can anyone answer this.Ive got quite a old computer, i have had no problem with it, up to now. Basically i went on it a week ago. When i went on programs, the cursor started flickering and sounds from the speakers.Now it did this when i went on the internet, also when i clicked on address bars i would get 00000000 come up and i can't get rid of it. I have got windows xp pro. I tried windows restore but that has made no differnet. Is the computer on its way out. I can't install anythink because everytime i click on a window i get the noughts. Can anybody give me a idea please.
