check if Oracle services is running or/and set as "automatic".
When you install Oracle database, it should be neccesary look for any error at the installation log. Did you "omit" any error when you installed it?
The easy way will be reinstall, probably you solved the error, but if you are learning, this is a good time to know how to solve problems. I encourage you to try, we are here for help you :)

OracleXETNSListener should be running.
like osama told you, when you get the error again, post the last 50 lines of alert.log ($ORACLE_ BASE/diag/rdbms/sid/SID/trace/ALERT<SID>.LOG also "select * from v$diag_info" or "sho parameter background_dump_dest"?
HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\oracle_home_name check for ORA_SID_AUTOSTART and tell us the value of this key.

Just One Question Why you don't want to post alertSID.log is this secret
