Madame Guillotine

On my sites, I get random errors. Okay, let me explain this a bit better. All along my many websites, randomly, scripts just spit out errors. I can refresh once sometimes and they go back to normal, or sometimes I can refresh 20 times and they still don't fox themselves. And it's never the same script, they just error randomly. If's always a guessing game to see which one, but it's always one. My company says it's something with my files. But, I'm not doing anything differently from others who have sites working fine. I just want to understand what the errors are related to so that I can see about fixing them (or moving hosting companies). These are some of the errors that crop up, just a sample of two of the scripts that mess up. The others are generally the same with a few differences.
