to avoid any conflict i would remove or dissable any existing sound card and remove any drivers related to it so in effect you have a clean install of a new component, then follow the install instructions for your new card
Darren Sorry to sound so vague but I had a quick look at the back of the Pc their was no soundcard fitted to the PCI slots so it must be on the MOBO so I presume the first step is to disable the soundcard in the BIOS so how do I do this cheers for replying
If you are planning on purchasing a new sound card and have on-board audio it is highly recommended that you disable the on-board audio before installing the new sound card. The following is the two methods that on-board is disabled.
The majority of all on-board sound cards can be enabled or disabled within CMOS. Additional information on how to get into CMOS can be found on our CMOS page. If your computer does not have an option within CMOS to disable the on-board audio it is likely that either the motherboard has a jumper which can be set to disable the on-board audio or the on-board audio will disable automatically when the new sound card is installed into the computer. Please refer to the motherboard manual or contact your computer or motherboard manufacturer for additional information.
normally its in the advanced set up menu somewhere.all bios menus will be slightly different in layout.
look for 'audio device' or similar and just set to disable.
ps.before doing disabling in the bios uninstall any drivers for the old onboard device if listed in add remove programs and look in control panel/device manager for the onboard audio and right click it/properties and choose 'do not use this device(disable)' first then shut down and install the new card.
start up and enter bios straight away and disable the old device.save and exit and let windows start up.install drivers for the new card.
on my friends its under features just look in all the lists in the cmos if its not there it maybe a jumper to reset.your best bet is to find make and model of the mothereboard and download the manual from there website.
