Your best bet is to find a company that has its own IT department. After procuring an entry level position as, perhaps, a file clerk or data entry clerk, make friends with the IT department. Make it known that you would like to go further with the company by obtaining a position with IT.

Also how will employers react knowing that I ultimately want a job in computer repair. Will they deny me a job because they think I am not going to stay at that job.

Yes, you will be denied jobs if the empoyer thinks you are going to quit as soon as the first computer related gig comes along. When you go for your interviews, the interviewer might ask you something like, "Where do you see yourself in 3 years?" Say something like: "My goal is to work and study my way into a position within (name company)'s IT department."

With that answer, you are saying you still want to stay in that company but doing something in a higher level.
