Technical Difficulties ... Again

Hello! If anyone knows anything about computers, can you shoot me and e-mail or give me a call. We are suddenly getting these gdiplus.dll missing errors. It seems to be effecting the way we view photos, our desktop is kaput (it's that white restore screen), and is causing some other errors. This type of error is apparently not covered under our warranty and they want to charge us big bucks to fix it. Ugh ... if anyone can help, it would be greatly appreciated!
