Hello! I have Dell Dimension E521. Yesterday I have surfed internet and I have found information on Dells web site that there is update for my bios. I have download it and I didnt make bootable cd, but I run exe file from my Windows XP. When I finished with flashing and restart computer BANG! I couldnt boot it! It doesnt give any sign of life!
Hello! I assume that flashing bios killed your motherboard. You should call Dells technical support and tell them what has happened. I am sure that they will send you replacement for your motherboard. Next time, be careful and before you do some foolish, ask some skilled person for advice. I hope I've helped you!
