Hi all,
I have attempted to read through the entirety of this thread but gave up after about 20 pages. I'm hainvg a problem with this motherboard which is really confusing me. Firstly herei s my current hardware:
Asus a8n sli deluxe (bios:1004 beta)
maxtor 250gb SATA HD (unsure of model number)
XFX 6800 Ultra Pci-e GFX (model: PVT45FUD)
1Gb Corsair DDR (TWINX1024-3200XLPRO) over 2x 512mb sticks
Antec neo 480 power supply
Pioneer DVD R/W
Pioneer DVD reader
AMD Athlon 64 3500+ w/ stock AMD cooler
And configuration details relevant to the question:
DDR is running at DDR400 in dual channel configuration
GFx card is currently plugged into the blue pci-e x16 socket and the tab selecting between has been set to single graphics card. Incidentally mine was one of those shipped in the multiple gfx card position when the manual said it was single by default.
I have plugged a molex power line from the psu into the EZ plug socket and also supplied the Gfx card with an independent line from the PSU.
SATA drive is plugged into the Nvidia SATA controller on socket 1.
I'm running Windows XP pro
And now the problem:
Ok.... the long and short of it is I cannot get the motherboard to post unless everytime I power it up I clear the CMOS ram prior to powering it up. If I attempt to change any settings in the Bios and save on exit, the motherboard hangs, display goes dark and monitor goes to standby.
However, if I go into Bios and simply exit and save without saving changes, I am able to reboot and post successfully.
If I simply accept CMOS default settings and boot into windows the system performs flawlessly... really good performance however if I want restart at all I need to shut the machine down, kill the power, reset CMOS then I can power back up successfully.
You may ask how I managed to get windows on in the first instance... well as I described above I had to use the above procedure everytime the installation process wanted to restart.... :roll:
Possible fixed I have already tried:
I have used three different bioses.. 1002, 1003 final and now the 1004 beta and each bios manifested the same symptom.
I have tried the system with nothing plugged in except GFX and one dimm to eliminate power as the problem... no go unfortunatley... same problem.
Has anybody experienced this symptom and found a cure/work around?
With thanks,
John, UK
