What do I do to fix my Wii console? Please help me!?

about 3 weeks ago, i was playing call of duty black ops, and my error : could not read disk thing popped up. i thought it was the lens and made a lens cleaning kit, and cleaned the lens. then it still didn't work. 1 week later, it read the disk, then stopped reading it right after i pressed start. it will not read any disks. 3 days ago, i took it apart. the lens wasn't dirty, but it made a funny sound and would not spin the disk. so i took apart the disk drive and looked at it, put it back together, and left it sitting there for 3 days. tonight i put in wii sports, and it read it just past the beginning stages, and did the error menu. then i put in black ops, and it read, and spun the disk with the funny sound. it actually got to the menu, but when i hit mulltiplayer, it went black, slowed down the spinning, and then sped up a couple times, making a funny sound, and displayed the loading... thing and then displayed the error screen again. keep in mind that i haven't hurt the wii in any way, i've taken very very good care of it.also after i cut it off after the error screens, the yellow light comes on. every other channel works fine, and its always made that sound when i put a disk in from day 1. i am very mad about it doing me this way and do not know what to do any more. i also am out of warranty, and can't send it back to nintendo. PLEASE HELP!!! Thank you!
