Go to this site:

And download all the drivers that pertain to your system, 32-bit or 64-bit.
Install them and that should sort most of your problems out.
Have a look in Device Manager, how many yellow triangles are there?
The six beeps usually indicate a failed graphics adapter. You should uninstall the graphics card and remove it, if it is in a PCI slot.
Otherwise you will have to reset CMOS.
And connect your monitor to the mother board.
Then install the drivers and do the restarts.
When your system is sorted, shut it down, put in your graphics card, restart the computer and go into BIOS.
Look for a setting where you can choose default VGA device and set it to PCI if you can, rather than 'on-board'.
Connect the monitor to the graphics card and restart.
Install the graphics card drivers and let us know how you get on.
Okay?
