I called to find out how much would it cost me to fix my computer problem as it was switching on and off always and upgrade my hard drive, and after they took a look at it, it appeared to be the motherboard was dying. They had to change it, upgrade the hard drive, install a windows platform, install all programs I had previously, and install an anti-virus for me at 90 $ only !! The estimation at another competitor was 185 $. Very satisfied with the service. Thank you Tech-Bird :)
