epson printer 870

Please can some help

three weeks ago I had a virus on my system could not drag
or drop or burn anything to cd
so I decided to re-load xp in a different section
having done this I copied everything that I needed and
formatted my hard drive and re-loaded windows xp using
the four disks that came with the pc
Every seemed to working ok but seven days ago my printer
kept showing a connection error so I decided to uninstall
it
and reload the printer software but since then my printer
will not work
windows has found two drivers 870 and 870 esc/p2 and then
it shows a error screen saying there has been a error in
loading the drivers
Have spent the last few days speaking to Epson but they
asked me to contact Microsoft and Compaq but that as been
going on for over two weeks

Cannot find my LPT1 printer port when you click on
printer properties and click ports
