I was doing general case cleaning and cable management today, during which i removed everything from my case, blew everything off with air, and reassembled it. Now the comp wont even start, the fans wont spin, the HD light just blinks once and thats it. i put it back together exactly the same as i took it apart, so i dunno wtf happened to it. any ideas on why it wont boot? the mobo is a MS-7191 v1.1 PSU is Antec 500W im getting worried here cause i got a huge lan coming up an i need to be up and running ASAP!!
