Ms 6340 ver5 n1996 where is the reset switch.

Here is the reset switch that you have requested. Have a nice day.

Reset switch won't work although it is connected

Hello john:
Here is the link for your manual: "CLICK HERE"
By reset switch do you mean the reset button on your case? If it is it should be a little indent about the size of a pencil or pen point near your Power button. Of course that all depends on the case your PC has. Just push it in with a pen and that will put your PC on reset.
As far as your motherboard goes there are two sets of pins on your board that can be hooked up to a reset switch. Its in the manual link I gave you.

Hope this helps, if it does just click the thumbs up.
Sincerely, Peter N.
