Red is Black

After I installed my new CPU fan everything that's pure red turned black. Now my hp and party hp bar is black, which doesnt show at what hp percentage they are, thus preventing me from playing classes like healer. I just see when they die
Anyone know what's going on? I tried removing and installing my graphic gard, but it didn't help.

EDIT:
NVM it's fixed now

So what fixed it? You can't leave us all hanging like that...someone else could have the same problem.

Well I installed and uninstalled my drivers, and since I had to restart I changed ports on my video card (I have 2 same ports, don't know what they are called) and made sure the cable is fuly connected in my monitor as well.
It worked after that.
