Request for some CSS help...

Hello!

I have a theme that has a CSS styling element that I do not care for...but for some reason, I am having a hard time figuring our how to fix it.

The web site is http://www.suzukalypse.com

If you go to it, you will see that when you hover over a post title, it becomes an orange block. I would like to have this be "normal" where the text just changes color and becomes bold.

Also, the images on the right under "POWERED BY" has an odd orange underline when you hover over it as well.

Can anyone tell me what code to change and what to change it to in my CSS?

Any and all help is appreciated!
