So I bought this laptop (Dell Inspiron 15 i5548) around May of 2016, and it was fine and working well for the longest time. However, recently it has started acting up. For example, I can no longer click in almost any program, I cannot type in the Windows search bar, when I booted it up the screen started going flashing about 4 different colors. Now I have tried scanning for a virus about 2 days ago, so just a day before this started, and it didn't detect any viruses. Thank you for reading this and posibly helping.
