Hu urbs. Thanks for posting all of your PC specs. You have a nice system to run SWTOR on. Don’t see any type of hardware problem unless you are trying to run SWTOR on max settings or at max resolution on a 1920x1080P monitor.
Try the following. It may solve your issue…
1 – Fully update Windows XP. If you are not sure how to do this then checkout YouTube for videos on how to update Windows XP
2 – Download and Install the latest driver for the GeForce 8800 GTS directly from the nVidia site.
Here are the exact 8800 GTS drivers for your Desktop PC running Windows 32-bit:

3 – Restart your PC after the drivers have finished installing
4 – Download and Install the Free version of “Game Booster”: ttp://www.iobit.com/gamebooster.html
(Most people use this to speed up their gaming PC but also temporarily closes background apps and processes that can be causing SWTOR errors or crashes.)
In case you need it I created a video tutorial on how to install and optimize Game Booster. The video is at the end of the article:

6 – Run SWTOR, but do not play it yet
7 – Go into the graphics settings. For Testing Purposes Only, set the graphics settings to the absolute lowest possible. Checkout my screen capture below and copy every setting.

9 – Run SWTOR. If it runs play it for at least 10 minutes.
Does it run okay now? If yes then go into the graphics settings and raise them to around medium settings and see how smooth it runs.
SIDE NOTE: You have Windows XP 32-bit with 8 GB of RAM installed on your desktop PC right? Your desktop PC is only using 3.2-3.4 GB of RAM. It ignores everything else. This is normal for all 32-bit operating systems even the newer Windows 7 32-bit. I highly recommend upgrading to Windows 7 64-bit. Do not get WinXP 64-bit since a lot of games do not support WinXP 64-bit.
