I hope so! But even that is still pretty high for operating a high performance computer 18-20 hours/day.
Maybe he'll post some more details on the environment and the system's components' makes and models.
I certainly hope so. Forget the computer, I don't know any worker who can work in 400c temp.
I don't think I can help very much. I don't know what "very poor response from machine especially from inbuilt voice card." means, nor do I know what the software you use suggests you need. I do know that if your using an old P4D that the newer dual core Atoms are as fast as those. Any of the new CPUs should show a big improvement in CPU power compared to the old P4.
i am sorry its 40 C to 45 C. coz its installed in open and public areas. we are using windows Media Player to play Advertisements. and for better performance we are using external Graphic cards (A.T.I.). is there any other API , or software through that i can Achieve my task.
On the old systems you have, the audio codec built-into the motherboard may sap power from the CPU if that is what you are talking about. The best way to fix that is to spend about $20 (in the US market at least) on a cheap add-on sound card. Make sure you get one with a dedicated processor, some of the really cheap ones are basically just cable connections that end up using the CPU for decoding audio.
