IP address conflict
My Dell XPS laptop Win7 computer has been puking up "Windows has detected an IP address conflict" many times/day. Did some research, tried all the recommended fixes (ipconfig release..etc) nothing ...

It's not unusual to see IP conflicts using DHCP, though not necessarily common.
Seeing IP conflicts on a network using DHCP almost always points to a network configuration error. I wouldn't classify this as a "It's not unusual" type event.
DHCP will send out a unique IP address to a device identified by MAC address and keep it allocated for the specified time or until told to release it. It WILL NOT send that same IP address out as long as it knows it has been assigned and is still considered active.
It's not necessarily a DHCP configuration error if a conflict happens though. It could be a misconfigured device that is using a previously assigned IP address that it no longer has permission to use.
Either way, a properly configured network and devices using that network should never see an IP conflict when using DHCP.
Randomly rebooting systems, servers and routers to try an "fix things" can cause some of this to occur though.
