Chrome issues

Hi,

First off, I downloaded windows 10 a few weeks ago and it was working fine, but in the past few days, chrome has not been working as it should. The icon is missing on the task bar. Whenever I click on it from the task bar, it usually says Unspecified Error no matter how many times I try. Every once and a while it may open luckily. Help! I do not know what to do and it is very frustrating. I am starting classes back Friday so I need it working as it should. Thanks.
