So today I downloaded an art program. Along with the program, other files and programs were downloaded as well (not very smart of me, I know). I deleted all (I think) of the programs and files and went to open google chrome to find an error saying "unable to connect to the proxy server". I looked up on the internet on how to fix this and tried my best to get it to work. Unable to fix my problem I decided to restart my laptop. Now when I turn it back on, it is just black. The dell logo will come on and then it goes dark, but the fan is on and I can see my mouse. I really, REALLY need help. Replacing my laptop is not an option and it does not have a cd driver. I believe that my laptop is a dell xps 11 core i5... if that helps.
