hi i just put a geforce 512mb graphic card and put in another 1gb memory in now it seems the cpu fan is more noisey than before any help will be gratefully recieved philip
Is it the casing that is more noisy ? If you have been in the box you need to check that the card you installed is screwed down as well as the cover and what the case is sitting on.
I assume the fan is not gunged up with dust is it ?
You could try cleaning it anyway with a vacuum cleaner / paint brush....
