Please help
I am building a new system (for the first time) using;
Abit BD7-Raid Mainboard
P4 sct478 processor with thermaltake volcano
2 x 256MB (184 -PIN DIMM DDR PC2100 UNBUFF.)
2 x IBM 60XGP 40GB Hard Drives (IDE RAIDport)
Asus V8200 Geforce3 AGP graphics card
Aopen H600A P4 ATX Case with 300W PSU
TDK Cyclone 24x 10x 40x (with DVD Rom in primary IDE port)
Sony 16x DVD Rom
Sony floppy drive
Creamware Pulsar II V3 PCI soundcard
Diamond Supra Express 56iPRO PCI modem
logitech ps2 keyboard and mouse
Iiyama 451pro 19" monitor
I have connected all of the devices following the instructions that were shipped with the mainboard and before booting up for the first time I checked and re-checked all of the connections. On booting up, the system got stuck on POST code A7 and the case speaker omitted a long beep repeatedly (ThePOST code sequence is C0,C1,A0-A7). I have subsequently removed the sound card and modem only to greeted with the same response. I then removed the AGP graphics card (with the same result) and then the memory which responded with an E3 POST code. I then replaced the memory and graphics card and cleared the CMOS using JP5. On booting up the machine it will now pass POST code A7 the first time but it will go back to it and get stuck this time with no beep (The POST code sequence is C0,C1,A0-AF,C0,C1,A0-A7). I then inserted a system disk into the floppy drive which did not help and the floppy drive didn't light up or appear to work (a floppy drive from another computer similarly didn't work). I Have also tried connecting the hard drives to the primary IDE channel with no change.
The POST code A7 doesn't appear in the mainboard manual and I have searched the internet from Award Bios POST codes and cannot find mention of it anywhere.
I would be extremely grateful if you could point me in the right direction and advise me how to get the machine to work.
A prompt reply would be greatly appreciated as I am about to pull out the last strand of hair from my head. |

The long beep indicates a RAM problem but if it is a long beep followed by 2 short beeps it is a video problem. This may also be causing the A7 error, I recommend using a PCI card and swapping the RAM out for testing purposes this will also remove any doubt about the AGP port being at fault. |

One other thing, please don't post the same in more than one section as this leads to Mayhem and Hysteria, Mass confusion, dogs and cats sleeping together and what not on the boards. |

Chris, thanks for the e-mail. You were absolutely correct.
i had the same problem on the same board. After Chris' suggestion via e-mail, I pushed the RAM down as hard as I could without breaking the board. Post code A7 gone. |
