You might have a problem with Wake-on-Lan - I would call your internet provider and see if the DSL modem is using this feature to restart the computer. You might also turn off WoL within the BIOS.
With modern computers, even when they are switched off, the Network Interface Card (NIC) is still powered (you can test this by looking to see if the green light next to the RJ45 Ethernet port is still lit when the computer is off). This means the NIC can still sense and process network traffic, although it does not have an IP associated with it in this off state. WoL works by broadcasting a specially formatted Magic Packet to all computers in the subnet. This Magic Packet includes the MAC address of the target PC repeated 16 times in the data section. The target PC receives this broadcast packet and when the NIC identifies it as a WoL packet and the MAC address is a match the boot procedure is initiated via the appropriate hardware channels.

No you can't - not if you don't know what a BIOS is.
