|When you formated, you lost all the drivers. You should have backed them up BEFORE you formated or at least made a note of all your devices so you'd know what to download.|
Why was it necessary to reformat?
"THe computer is not connected to net. I will have to install any driver through CD"
Then you're going to have to download the drivers using a different computer, burn them to a disc, then install them. At the very least you will need motherboard chipset, video & sound drivers.
"display adaptor as standard PCI graphics adaptor VGA"
That's just a generic listing showing that no drivers have been loaded. If you don't know which video card you have, open the case & look for a model number on the card. And since you'll have the case open, you'll be able to identify the exact motherboard model number & chipset used on the board. You may also be able to identify the board from the BIOS string along the bottom of the POST screen during bootup.
"Mother board is zida technologies, bxi atx"
Zida Technologies is long gone. Their boards were known as "Tomato", if that's any help...here's an example:
"the sound card is CT4810"
That one I *may* be able to help you with.
