You need administrative control of the DHCP server, and either program
a static address for your MAC, or reduce the address lease time. 
There is no way for a DHCP client to "reject" an address.

But the problems you describe sound like some other device on the
network has the same address as your PC.  You might try some network
monitoring tools like tcpdump or ethereal to see what is going on.  In
particular, pay attention to ARP requests and responses.
