I'm sure this is a question which has been asked many, many times...……………..I stupidly decided to update my BIOS from it's factory default with a low battery. Guess what...…..I had a powercut Now I'm getting three flashing blue lights followed by three red - also seven beeps. I've tried disconnecting the CMOS and the internal battery with no luck. I've tried formatting a USB with rufus, copying Dells .exe file onto the stick (File Name: Alienware_15_R3_17_R4_1.5.0.EXE) from Dells website with no luck...…….PLEASE HELP!!!!!!!!!!!!!!!!!!!!
