HELP no connection!

Hi basically i got a virus and now iv finally removed it successfully my internet wont work.. where i plug the ethernet into my network card the light used to be solid but now it flashes (blinks) instead. and also the light on my router indicating theres an active ethernet cable in the port isnt coming on anymore.. if i run a diagnostic it say the cable isnt plugged in. i kno its a working cable because it works with my ps3. ive reinstalled my os but no luck.

please help

hey thank you,
i presumed the driver was reinstalled when i redone the OS because i uninstalled them before i redone the os. im pretty sure its not the wiring because i have 2 ethernet ports in the card and they are both doing the same thing. yes i done a full reinstall i even formatted the drive first (it only took like 3 seconds to format which i dint really trust tho). im sure the virus is gone specially after a clean reinstall of the os. i just have one light on each port which blink orange. the thing i find the most puzzling is my router not picking up the fact a cables plugged in..
