Tagline, creative writing

Hi I want to write a tagline for my business which is a computer service business. My business name is "Myname Computer Service" and the tagline I want to write is my problem basically. I am clearly not a creative writer; however I came with the following
1) Fixing computer with quality
2) Quality fixing computer problems
3) Repairing computers with quality

I want to say that my service is to fix computers and my sertaglinevice is quality one. Could you please help with editing / rewriting any of above if you think I should do so. If you can come with better one then I would appreciate your suggestion very much.
Thanks
