Computer doesn't download files?

My computer won't download files or any programs even though my Internet is perfectly fine. I tested on my mobile. I did a returned to a restore point too it didn't seem to do anything at all. My laptop is a Lenovo z50-70

Maybe you ran out of hard drive space or don't have an administrative account?

Internet explorer has settings that can block downloads. If using IE, look at Internet Options, prob the Security tab
