well this can be as easy as some WD 40 sprayed on the computer over the course of a few days. Worst case you may have to take the computer apart. So lets pray for an easy solution. First, take the face plates off on both sides. After that, if possible take the computer covers off(this just makes it easier to reach all the areas. Soak in WD 40 2-4 times a day and see if you can get any movement after day one. DONT BE TOO FORCEFUL! Remember that the computer may have rusted out parts. If you can get a little movement repeat the step until wheel covers are free. Feel free to email me if you have any questions.
