"I was totally awestruck by Mike's professionalism, knowledge and honesty. He was able to reassure me that my used computer is in tip top shape and has more memory then I even imagined. He was able to remotely get into my computer to check it out since he is in Arizona and I am in Oklahoma. Normally I would not have allowed this-but thanks to Mikes many tremendous reviews and A Grade I trusted him and do not regret it. In my opinion he deserves an A++! It's been 20 years since I have owned a desktop computer and I'm obviously not tech savvy! Mike did not take advantage of that and was even kind enough to share some info with me free of charge. I have already opened a file (in my filing account with his name on it)! I am making a list of things for him to help me with and will definitely be back in touch with him. I highly recommend Mike's company to anyone looking for an honest, reputable computer repair person."

"We took our computer to Larry in hopes of a screen repair. Unfortunately Larry worked very hard, and found out that our computer was not repairable. He offered to give us a loaner laptop while he worked on our laptop. He then helped us choose a new laptop, and then offered to help us transfer all of our information. He made sure the job was completed. He went above and beyond our expectation to help us with our situation. The response time via text, phone, and email was timely!! I would highly recommend this company for any computer services!!"

"I just purchased my home and the home inspection report listed some electrical repairs needed. I made an appt. with Paul at PS Electric. He was on time, very thorough and answered all of my questions. Dealing with electrical stuff can be very intimidating but he was honest and didn't try to "scare" me into fixing things that didn't need to be repaired. He spent well over an hour going over my entire house only to find no repairs needed! I truly appreciated his professional attitude and the fact that he is very personable made the experience that much better. I will use them again!"

"I called and they came out right away and got started on the work. Our offices flooded so all of our computers, server, network and surveillance cameras were out. We purchased the computers but they upgraded/replaced everything else and were able to recover our files from the old server. Any time we have called for help, they were available and got the issue taken care of right away. Great company and friendly service - highly recommend them!"

"Very knowledgeable. My OC crashed and my recovery key had not been attached to my microsoft account. He recovered my LocKey and restored my OS. He also upgraded my mechanical hard drive, which was old and causing the problems I was having, to a solid state drive. He also upgraded my ram to keep up with everything and cloned my old hard drive to my new one. While he was here he also reconnected my ring cameras. Yes he is Ring certified and diagnosed my problem with my outside camera systems to a bad monitor. I had an extra flat screen and he installed that also. One service call three jobs. Very versatile guy. Very personable. I will use him again and recommend him to my friends."

Computer Repair questions, answered by experts

Aim for a uniform, smooth joint to ensure a good electrical connection. If it looks crusty and uneven, your iron tip might be dirty or the joint isn’t hot enough. To keep the iron tip clean, wipe the tip with a damp sponge or brass tip cleaner when you spot black spots or rust to remove any oxidation and flux residue. Tinning the tip surface with a small amount of solder offers a layer of additional protection.

Costs depend on door material, labor, additional hardware, and whether structural modifications are needed.
