What can be wrong?
There is some sort of resource constraint preventing Postgres from
handling all its requests.
So:
Do you have any additional extensions/modules installed in Postgres?
What are the hardware specifications for the machine, memory, CPU,
storage,etc?
What is the work load on the Postgres server?
What does the system show for load during this time?
What do the system logs show?

I did not find anything strange. This problem also occurs with Windows 7 64
So: Windows 8.1 Pro
Do you have any additional extensions/modules installed in Postgres?
I have, Default Installation
What are the hardware specifications for the machine, memory, CPU,
storage,etc?
Intel Core I5 CPU 3.00 GHZ 8GB memory
What is the work load on the Postgres server?
The workload for this server is small, only a web application with few
users.
What does the system show for load during this time?
Waiting time out to start the server
What do the system logs show?
2016-08-03 08:42:39 BRT FATAL: lock file "postmaster.pid" already exists
2016-08-03 08:42:39 BRT TIP: Another postmaster (PID 2968) is running
under the data directory "C: / Program Files / PostgreSQL / 9.5 / data"?
Well this looks like the Postgres log and it is showing that you are
trying to start Postgres when there is already another instance of
Postgres running.
What does the Task Manager show is running?
When I was talking about system logs I meant the OS logs, I was not
clear on that point.
