Font Problems

There is something wrong with my system's default font. My whole system looks normal, and even the registry I looked up looks normal too. But when it comes to browse some websites (I'm using Firefox 4RC). Everything's bold!

I tried IE9, it's also bold, same as Firefox. But the others like Opera and Google Chrome, they look weird, they set it like Times New Roman and some others.

I tried to reinstall all my internet browsers, still have the problems.
And I even downloaded the registry file VistaFontFix, still have the problems.

Your website also set in bold too. Could you help me how to fix these problems?

Sorry for the late reply. No it doesn't work.

Before this happened. I deleted all the registry issues using CCleaner with no choices but then it went messed up even I already imported backup registry. So I used System Restore but there was an error during the boot mode, the start-up didn't run properly, then I entered repair-mode. My computer was fixing itself automatically until the System Restore showed up again. I waited like one hour. I logged on, and it looked like everything's fine but not for all internet browser! NO GOOD!

Here, some images.

Firefox/IE


Google Chrome

It's all fix now!

I was regediting to find out what's in the font folder. It was the Left 4 Dead fault which corrupted the fonts after I uninstalled the game, so I rename into the normal one.
