web pages don't load properly

back ground colors won't load on web pages. I use modzilla but the problem also presents on internet explorer as well. I first noticed it on myspace, the background colors on my page were not visible. I restarted in safe mode and the problem was solved. It's not only the colors, some links aren't visible either. It's obviously a setting problem, but for the life of me i can't figure it out. I've used all the resources that i have available to me with no success. Please help. If anyone knows the solution please respond. Thanks.
