AN7 - Won't pass POST Screen anymore - Code 5b - Advice sought!

Hi,
oh dear, I have a problem with this new AN7. It won't go past the initial
POST screen. The PC powers up fine, and beeps just once (as normal) but then
it will just stick on the coloured POST screen showing code 5B on the
motherboard?(looks like 56, but is 5b). I can add that it has been working
fine for 4 days, but showed this problem about an hour after I first built
it and powered on.

The first time this happened I had to do a *Brute-Force* CMOS reset. Clear
CMOS doesn't work like I am used to with previous ABIT boards, that is
changing the jumper and removing the power lead from the back of the PSU.
This board will not reset unless I take out the battery and unplug the ATX
cable from the motherboard (+12v lead too!).

Here are the tech specs:

*SOUL-RIPPER*
AN7 rev1.0 (BIOS 13)
T-Bred XP2400+ (AIUHB)
512MB (Single Stick) Crucial PC3200 (CT6464Z40B)
Sapphire Radeon 9600XT (FireBlade Edition)
Western Digital S.E 120GB SATA (7,200rpm - 8MB)
LITE-ON 52x32x52 Burner
LITE-ON 16x DVD
ANTEC SX835 II
ANTEC 350w Smart-Power (Dual Fan)
4 x 80mm Case fans
WinXP SP/1
DX 9.0b
nVidia Drivers (CD)
Cat 3.10 (CD)
SYS: 25°C
CPU:35°C Idle - 56° Load

I am doing a *Brute-Force* CMOS reset now, and if that works I will proceed
to update the BIOS to v.14. Oh dear my Brother is coming to collect this PC
today. . .bummer.

Any Ideas?

 

Hi,

OK it's working again now!. Did a complete *Brute-Force* CMOS reset and the
system works great again. Just to be sure I flashed to the latest BIOS
(#14) to help prevent this *Code 5b* situation returning.

Not sure why the AN7 doesn't like to to do a normal Clear CMOS, anyhow the
situation *seems* to be resolved (for the moment )

 

Hi,
what is a *Brute-Force* CMOS reset ?
Tnx!
Alex

probably moving the jumper to clear the CMOS and/or pulling the battery with
all power removed...

Hi,
The *Brute-ForceT* CMOS reset is switching the Clear CMOS jumper, taking the
plug out the back of the PSU, removing the battery from the mobo and finally
removing the ATX power cable & the 12v cable from the motherboard.

I have never had to do this before I got the AN7, but it just won't *reset*
if I do any less. I found this method buried deep in the help section of
the AN7 manual. . .
