The system being slow could be caused by various components. We do not go by the online/offline performance evaluation to the hardware functionality.
Its great that you started out by isolating the RAM modules - which is something we would advise to test first as well.
We need to diagnose and isolate the source of the issue. So, restart the system and press f12 key on startup - choose diagnostics. Let it run a basic test and also run a extended / thorough tests on the harddrive and the RAM modules. If there is a hardware fault, it would be reported. This will help isolate any hardware failure.
If no errors are reported, then try updating the BIOS and check - http://dell.to/1zEqew5
Also, from the same link - download the service manual and see on how to reseat the RAM modules on the system - try using one RAM module at a time and see if the system works fine. And also write a detailed description if the wireless does not work after you managed to fix the system slow issue.

Start with an extended diagnostic on the hard drive - F12 at powerup.
