Greetings. My name's Sanjay Patel, and I currently hold an honorary Master's degree in the field of Computer Science. I am aware of, and have personal knowledge related to your question. There are computer maintenance businesses which are probably in your area, however they come at the cost of hiring a professional to enter your home. There may also be some local destinations where you can drop off your computer and wait to have a technician look at it. These options can often be costly, and pretty inconvenient. The answer to this question can probably be found doing a little extra research on Google.
A well-running computer can be a hard thing to maintain. From my experience, there is but only One software which is reputable- and consistently reliable for healing sick, slow computers. Reimage™ is a world-renown, easy to use software designed by Forensic scientists and made for the average person. This thing will fix literally just about ANY problem you could possibly be having with your PC. Reimage was recommended to me by a Professor during my 2nd year of Graduate school.
