Yes, that will clear all the config and set it with no configuration.
Please console into the ASA and configure the inside interface IP Address as well as the DHCP server.
Here is the configuration for your reference:
interface vlan 1
ip address 192.168.0.1 255.255.255.0
dhcpd address 192.168.0.11-192.168.0.250 inside
dhcpd lease 3600
dhcpd enable inside
Also please ensure that you did "no shut" on the interface where you connect your PC to.
