My computer was making a lot of noise, so I thought I best open it up and take a look. Well it just seems to be that the CPU fan is loud, never realy noticed it before. However, now I am unable to get a signal to the monitor, ie. it just comes up with 'no signal input'. I tried taking the VGA card out to see if the motherboard beeped when it 'posted'. But it [motherboard] did nothing. I am going to try putting in my old graphics card tonight to see if that works. The funny thing is that the fan on the current graphics card works fine it just seems to be that the monitor or graphics card has stopped working.
The card is a Geforce FX5200 with 128mb ddr ram. If that makes things any clearer.
