Hi. I have a relatively new (since January) system that I built myself, despite not really knowing what I'm doing. It's working pretty well, except that the fonts in PDF files are horrible. I mean really bad, like I get equal signs where only one of the lines is even visible (that is, it looks like a minus sign). What I want to know is if this is because I went with a low-end graphics card, an NVIDIA GeForce GT 710, or something else and what can I do about it?
