PS2 making clicking sound when loading games

[dunedog]

I have a PS/2 modded with Infinity. It is model no. SCPH-50001.
It is starting to have loading problems with games. It does not matter if it's a backup or original. It will be in the middle of loading and then it seems to freeze and make a rapid clicking noise.

Is this a laser problem? If so, is it worthwhile trying the cleaning disks? Or is this a job to take it apart and try cleaning the lens directly? Almost seems like a mechanical problem since it's making that clicking noise.

If it is recommended to try a cleaning disk, any recommendations or warning of what brand/type to use or not use?

The unit is only 1 yr. and 2 months old.
