PC Performance (Noise)

Hi.

I've got a new PC about 4 weeks old, and i have noticed it's starting to make a noise when i'm online.

The sound is like revving a motorcycle up and down, or revving the car up.

The kinda thing Boy racers do at traffic lights.

I've got 3.5GB Ram

Any ideas?

Thanks

Do you mean only and always when online?
Only a certain site or any sites?
Is it coming from the speakers or the tower?
How long does it last or is it continuous?

Does the sound come from the speakers,pc tower or somewhere else?
Background noise whilst on the net can be the result of your ports being scanned or even worm attacks.
Do you have your firewall on?
Have you scanned with your anti-virur software lately and is it up to date?If not do so and see what it finds.
Also download and scan with this free version anti-spyware programme as well and let us know.

anti-virur = anti-virus.

Hi.

Thanks for reply.

The sound comes from the Pc. I didnt really notice but the same sound occurs when i open
some programmes on the desktop like Nero 8 or run
a full scan using Norton.

The sound is more present when surfing the Internet.

This is the PC i've got i put an extra 3GB ram in it. looking at the Specification, would you recommend adding anthing else to make the PC run better.

Yes to all above!

This pc has a smart fan system which means when not under load they do just enough to keep things cool.When running programmes,such as scanning with Norton the fans will up their RPM'S which could be the noise source.
Possibly a stiff bearing which sometimes will quieten as they wear in.Or even quieten down after the ps has been on a while.Hopefully it will settle down.
'would you recommend adding anthing else to make the PC run better.'
Well you've already done the best thing to boost performance by adding the ram.
The x1200 onboard graphics are a let down,but if you're not into gaming then it's no problem.
Not sure what mother board you have,but i believe the CPU(Sempron 2800+) is the largest you can have without a new board.
For the price you won't do better.
If it does all you want then there's no need to upgrade anything else.

Sorry,(Sempron 2800+) should be (Sempron 3800+) is the biggest your board can take.

I agree with mrwoowoo regarding the smart fan system (my pc does the same).

You may notice that if your processor is working hard you can sometimes hear a high pitched sound coming from that also.
