Ok, even I can't do everything. I don't sell PC systems, either - although I can recommend you to a well-qualified seller, if that is what you want.
But I can make you sure it can do it's work. Is your firewall working, your internet connection efficient? Your virus scanner is up to date? Do you have a backup system on a regular basis? And your backup data are even readable? By you - and nobody else?
Plenty of questions, aren't these? Maybe an analysis of your office tech work does let you sleep better. Sometimes it is good to have an external review.
This part of my work is a side aspect of my knowledge, which is well worth considering itself - even and especially when everything is up and running.
So if you'd like to rest assured -
ask me for a review!
