learning repairing computer hardware?

My suggestion google is a best way learning computer hardware etc.

If you want to learn just for knowledge, you can take help from online tutorials. But if you are looking for a business in repairing computers, you must have good knowledge and experience as you can not mess up with others system until you have knowledge about it. So just take some tutions. There are various tutions or coaching available to teach computer hardware repairing.

I took a month long course in Minneapolis some years ago, just learning to put a computer together. It's not difficult; it's like putting together a piece of furniture. In the employment world, there are some entry level jobs out there that will let you in as a high school graduate, but they'd like you to have at least an associates degree along with a CompTIA certificate, such as A+, Network, Security, and so on. Neither college tuition nor testing for those certifications is cheap, either. If you are opening your own business as a computer tech, potential customers would like to see your education and certification posted as well. Remember, in business, if you manage to damage someone else's computer beyond repair, you get to replace it.

There are many online videos for this purpose. You can learn easily.
