My computer has started bleeping all the time. It used to bleep once at start up and that was it. It now bleeps all the time it is running like one of those old tennis games you used to play through your TV. Have run a scan and deleted all temporary files and temporary internet files. Also, very slow at loading. Any ideas and solutions please?

Try the list to see if it helps...BIOS beep & POST codes

A constant beep coming from your system every second or so could be the result of either a bad or mismatched memory stick (if you have more than one, remove one and try the system, then swap and try again) or could be the result of a power loss from your power supply (unless your familiar with the voltage outputs and use of a multimeter this one is dificult to figure out). You can try removing the side panel and watch the fan(s) while running to see if the appear to be slowing down.
