We have a thermal camera to check for heat issues. Heating issues can cause all kinds of issues with computers. A hotter component will usually fail much faster than a cooler component. Computers can slow themselves down (throttle) when they get hot, which makes them run slower.
I designed a custom air filtration system to let us clean our all of the dust from your computer, without putting out a cloud of dust in our shop or opening up a back door. If we notice much dust in your computer, we will clean it out. A clean computer runs cooler than a dirty computer. Imagine a “bubble boy” window with arm sleeves combined with a Rainbow vacuum and you are getting close.
I (Airin, the owner of Tech208) started fixing computers for paying customers in the 1990’s, about a decade before I got my drivers license. Riding a bicycle 30 miles (round trip) to fix a customers computer is dedication, and I made that trip many times over the years (this is my first business customer, and I still help them out every few months).
I have over 30 years of experience working on computers, and I spent about 9 years working for HP assisting customers with issues. I spent most of that time as a Level 3 Technician fixing software, account, and domain issues. I also wrote tools that hundreds of other technicians used to get issues resolved more quickly.
