We Need New Computer System At Work

Our computers at work have been working fine since I have been there, a total of four years. Now all of a sudden, every other day or so, something goes wrong. People can't access the system, the system is slow, yadda, yadda, yadda. It gets old. And it is old. I think it just boils down to the fact that the computers and server is old. We need new stuff! I think we might need an Industrial pc or a collection of them, and a new server, and new everything. It all needs to be updated. And quickly, before we start losing business. And that would not be a good thing.
