I'm new, well relatively 🙂.
To avoid getting a whole ton of sarcastic and/or generally unhelpful responses to your future questions, try and do a quick search (there's a "Search this Forum" and "Search this Thread" button near the top right) .. chances are, if you're just starting off and have a lot of standard questions, they've been asked and answered over and over again. You'll save yourself some time waiting for responses and everyone on here from having to retype answers. They also recently launched this "Premed FAQ" section (I believe I gave my two cents on this same question, albeit in a slightly different form, on there a few weeks ago)
To briefly answer your question, every med school will take your undergrad institution into account differently, though (in my experience) more so in a situation opposite of yours .. if they know you're coming from a very competitive or rigorous program, they might cut you a little bit of slack. I've never heard of a school docking you for coming from a smaller university.
Also, the MCAT is a normalizing factor that helps schools make a more objective decision, i.e. if you have a very high GPA but scored quite poorly on the MCAT, it might draw attention to and put your high grades into context.
At the end of the day, though, if you have good grades, a solid MCAT and diverse clinical and nonclinical experiences, no one is going to reject you because you went to a CSU vs. a UC or some other school.
