sphenz.......When you are in your control panel ........in the system you should see a list of all the things which windows see as being installed.....you should have a small square in front of the name with a + sign in it ...
look down the list and see if you see anything that looks like sound or sound adapters , or Display adapter
perhaps you could tell us exactly what it actually shows.
usually the onboard periphials include.....vid card , sound card , perhaps a modem . Any other card would be installed in either PCI or ISA slots located in the lower part of the tower......
You didnt say if the monitor is working ok .
Please give us more information if you can .
