I know I've had issues with my comp a lot and I know I must be a pain....

But the inside of my computer keeps making loud clicking noises like a clock. Tic toc that kind of thing but more ragged and louder.

I have finally got sound on my comp after installing a new harddrive and I thought all my problems were over with.

Not having the best of luck are ya fella?

Not quite sure what to suggest to get rid of the ticking sound you appear to be getting, Not heard that of that sort of problem before

I'd reccomend posting your error on this forum : http://www.pcmech.com/forum/
One of the guys on there should be able to help... If its too complex there answer gimme a shout and I'll have a look what they say

There was a loose connection at the back and it was making a rythmic noise as it became loser.

That is a pure guess but after I put it in properly then it was fine.

My computer is completley sluggesh though, especially for a reasonably new computer.

Tell me you're not running Norton anti virus / Norton Security etc? I think it was designed to slow computers down by at least 50% if you have it, get rid and install something lighter; AVG or Avira.

Press CTRL + ALT + DELETE and look at TaskManager, How many processes are running in the background?

Like Mr I says possibly you could be running numerous virus checkers

Sorry for the late reply, only just seen it.

I think they've sold me a shit computer to be honest.
