Realtek RTL8139(x)/8130X Boot Agent...
Press F-10 to configure.
I pressed F-10 and most of the time the computer wouldnt read my commands. I got it once changed a couple and still nothing happened. On the next startup I pressed F8 which is boot menu, and i found a command to boot up on normal settings I got it and i was on my desktop, sinc ie wasnt on my computer for a while i scaned for viruses and did windows update I restarted, dumb of me! and same prolbem. I treid F8 again but it just kept saying put in a boot floppy or cd which i dont have, and now I everytime i start the computer nothing shows up the screen is black. the monitor doesnt read the computer anymore any suggestions. Thank you in advance.
