Hi. Apparently it runs the 64bit Windows 19 version, so it should be a dual-core processor of some kind at the 1.1Ghz speed.
This is going to be an "add more RAM from Amazon for cheap" issue, try for 2x 2Gb sticks, should run about $25US for the right kind by the model.
The next step is to definitely downgrade to Win7 as mentioned, it was designed to run the systems with those specs, & stick with the 32bit version - there's more software available that's compatible with 32bit OS versions than having to install extra software to run it on a 64bit OS.
Once You're running a 4Gb system with Win7, You should actually find all necessary hardware drivers for it, save all software installers You need, & then burn a copy of a live bootable linux OS like Puppy linux ... You would then boot from the burned CDR & run all internet functions & browing thru the linux OS.
This will keep You from getting viruses in the Win7 system. Even if You use porn sites.
