I assume that you are talking about the operation system being in Korean..and want it in English ..but this is not possible unless you have something installed that makes it display in English ..and the original operation system is in English ..but ..you need to know Korean to identify the program that changed it and remove it from control panel ...When you change the language from the feature in the control panel ..it only change the way you use the keyboard..and not the language itself .
If you really want it in english you will have to reinstall it again ..I assume you have windows XP sp2 on it ..cause no other will support the specs on this computer ...and in this case you will need an windows xp disk (boot-able ) and the instructions for reinstall if you do not know how ..
So ..either ask a friend to help install it ..or try yourself like it folows..
First to get a windows xp disk ..you need to download the operation system image ..from a torrent file ..and burn it by using a blank cd ..and Nero burner software ...(just double click the icon ..and if you have nero in the system it will burn it auto )
here are the downloads you will need in order..
first the torrent program needed for download the image http://www.utorrent.com/
second a Nero software ..need to be installed (use the cd key in the folder ) for to be able to burn the image with double click on it ...http://www.mediafire.com/?yznzmdonjgm
and finally the image with the operation system in english http://thepiratebay.org/torrent/6350899/windows_xp_sp3_genuine
install the first 2 programs ..than go to this file ..and press on download this torrent ..and confirm download ..and after 30 minutes you will have the image file in the computer ..It will notify you when the download is complete ..
After that if you have nero installed ..just insert a cd blank ..(never used) and double click on the image file ..and it will start the burning on disk ..
Once that you have the installation disk ..you have to set the computer to boot from cd in the BIOS settings ..under the boot sequence feature from advanced settings ..and save the new order with F10
restart the computer with the disk inside ..and if it is booting from cd ..it wil ask you to press any key to boot from cd ..and start loading files..
after finish loading files..it will show the agreement and need to be confirmed with F8 and will check for the other installations ..and display them ..
now is the moment when you choose esc ..don't repair..and select the C drive for the installation ..and enter to install ...format the file using format quick when prompted..and confirm the command..with F..after that it will start formatting ..and loading windows files...When this files are loaded ..it will restart itself ..and at this point you have to let it boot without pressing any keys..
From this moment it will install windows and your presence is needed only to make choises for name ..and time zone ..and network ..(choose the top variant for network )
when finish ..istall all drivers from the disk ..and download and install the programs you use..they are almost all available for free download on the net ..
If you do not have a driver cd for it ...it is better to download them from the ibm site ..before starting the installation cause after that you risk not to be able to connect to internet without the network card driver ..and will be more complicated...needing to use another computer and a memory device to transfer..them ..
I hope you will manage ..and I will link an tutorial about xp installing here ..just for to have an image ..
