What employers want in the IT business is EXPERIENCE. They know need to know you are able to diagnose PC problems effectively. If you have personal experience, that's a plus, but working in a certain business let's your employer know that you are capable of assessing a wide range of problems.

What I recommend first and foremost is an A+ certification. It'll probably be information you already know, dealing with the hardware and software aspects of PC repair. This certification is the industry standard for most, if not all, entry-level PC jobs. There's also many resources in which you can get study material for free so you could learn what is on the test. The test itself is updated every couple of years and pirates are always right behind it.

Check out the site CompTIA.org to learn what it takes to get into the IT business the formal way; as I see you trying to do. CompTIA are the people who administrate IT certifications. It also looks great on resumes. Afterwards you can look into Microsoft Certification; and Cisco certifications which deals with networking and routing for businesses or any size and flavor. Networking certificates pay lots, but it's also a lot to learn and it take more than just studying. Aplying the they studying is what is most important. 

For jobbing, check out dice.com and indeed.com. It's good to check there to know what many employers look for and maybe even get a feel as to what you want to do in IT in the long term.
