First of all you can try with the line input of your Pc audio card. There will be 3.5 mm stereo socket in the pc audio card (blue color ) which will marked as LINE IN. To connect the turntable to this socket you need a RCA to 3.5mm Stereo converter like on in the picture bellow. I have also added a link to a video which will help you to do the same. In the video the are showing a cassette deck. In you case Turntable in place of cassette deck. You have to set the switch on the back of your Turntable to LINE OUT.
Then you can use any software to record the signals from the LINE INPUT of your PC.
If you need a high quality recording the you have to use a special converter which will do the job neatly.
To convert or upload (copy) tracks in LP in good quality then you need a interface unit between the Turntable an PC. Which will convert the analog audio out to Digital signal ( RCA to USB). The unit will come with the driver for it. That you have to install on your PC.
Keep on thing in Mind that when your are using such a converter between Turntable and PC you have to set the switch on the back of your Turntable to LINEOUT.
Here i have added link which will lead you to such a USB converter. Which will provide you studio quality stereo.Manual for Stanton T80Video RCA TO USB converter3.5mm STEREO to RCA converter cable.
