Hi, I have been having some trouble with my dell inspiron 1545 over heating. I just bought it off ebay a week ago. I have cleaned out the fan filter etc and have made sure there isnt any viruses so I am now attempting to update the bios as the version I have on my laptop is 2009 and there is a 2012 version. I have made a bootable dos flashdrive and followed each direction on the dell website to make this. when I boot from flashdrive It takes me to somewhere where it then says C and at this point it I am supposed to type in the file name to access the bios updater. I have typed in a few things I thought it was and its telling me its a bad command line. Whats the correct name I should be typing in after C any other help/ suggestions would be very helpful as I am not as computer smart as most and my laptop just keeps overheating and powering off
