Font Issue

Hello,
Recently I've been having issues with the way text is displayed on my computer. Everything had been working fine until a few weeks ago, and I've had this install of windows running for over a year now with no issues.

Anyways, the problem is that a lot of text looks glitchy and is very difficult to read. This happens in most programs, not just internet browsers, although that it the main issue. Here is an example of the issue in firefox:

Text looks like this on most websites when I use the default viewing size on webpages, and zooming in even one click will correct the issue, but the problem is that that only resolves the issue for web browsing. Other programs can't just be zoomed in to fix it.

I've tried searching the web for answers but I usually just get threads etc about how to fix text size, for when programs have text cut off by too large a font.

Could reinstalling the affected fonts possibly fix this? And is there a way to do such a thing without reinstalling windows?

Does anyone have any solutions or ideas? I can provide more pics or info if necessary, let me know what you need.

Thanks
