    What computer model do you have & how old is it ?

    You reset what, many times ?

    One beep is normal. You have tried different Monitors with no success, so, If you have PC, Power off, Open case, unhook Monitor, remove video card, blow off any dust (can compressed air), then reseat card, etc & reboot.

    Do you have a bootable Windows CD ?
