Computer Hardware Help → Abit BD7 error codes and no screen output

Can any one shed some light on this I have just purchased a abit BD7 along
with a P4 1.6Ghz and a 256Mb DDR Ram. The graphics Card is a Sparkle TNT M64
SP5300. I don't get any screen output, and on the little internal error
screen I get the code A7 and a intermittent beep, this error code is not in
the manual, does anyone have any ideas.

AWARD BIOS BEEP CODES

The following are Award BIOS Beep Codes that can occur. However because of the wide variety of different computer manufacturers with this BIOS the beep codes may vary.

1 long, 2 short Indicates a video error has occurred and the BIOS cannot initialize the video screen to display any additional information

Any other beep(s) RAM problem.

Thanks tmw280z! I'll check it out. I made sure the video card was in all the way, also checked the memory chips.
