Chris has been a great help to me on several occasions in fixing computer problems (bugs, viruses, component failure, computer going too slow, etc). He lives in N17 and was on my doorstep in N22 within 30 mins of the first time I called him, and has even attended on Saturdays too! He’ll happily try to resolve the problem in your home/office, or can take your PC/laptop back to his workshop to fix it there if you prefer. His rates are very reasonable, and I have always found him to be a very trustworthy professional.
