The request failed or service did not respond in a timely fashion 2014 SQL server // SQL server agent cannot start

Question

"The request failed or service did not respond in a timely fashion."

TCP/IP

I have some problems, i have downloaded microsoft SQL server 2012 and it was working perfectly fine before, using my local server (my own computer). but there's this day, it decided to not connect for me. so i went to google, searched on how to solve this problem.

• adjusted the inbound to accept port 1443.
• disable TCP/IP and enabling it again (tested both ways).
• uninstall SQL server 2012 multiple times and reinstalling it again.
• check service where both SQL browser and SQL server is there.
• downloaded SQL server 2014 instead.
• tried localname\SQLEXPRESS
• find server name using SQLCMD -L
• SQL server agent start mode to automatic

what else could be wrong? it couldn't start still...
