total newbie question but can someone give me a hint as to starting bfgminer completely auto when starting win7 64 bit machine. I have saved config file but each time I launch bfgminer.exe I still have to type M+ and then com3 to get it going. I also have AMD 280X graphics card installed and would like to mine from that same time but when I get that going it just overheats and bfg shuts it down even in dynamic mode. Any pointers to a nice easy tutorial would be very appreciated   
TIA
