Help! ASUS P5K Premium

[xiao]

i jsut bought a OCZ 2GB ATI XFIRE CERTIFIED DDR2 PC2-6400 KIT OCZ2A8002GK
and ASUS P5K PREMIUM WIFI-AP P35 1333FSB DDR2 PCZ MOTHERBOARD

but heres the problem

if i go into bios setup, and i change anything, as minor as diabling the boot logo, and i press F10 to save and exit. the computer shuts down and does not restart. when i do switch it on again it does not POST. i have to clear CMOS for it to post again, it has an error and asks me to reset to default settings or changes setting manualy, if i change setting manual the same problem will happen, if i change setting to defaut it will go into windows.

Once it is in windows, and i finish using my computer and shut down, when i switch it on again, it give me a death by blue screen error about ACHI, i have to clear CMOS each time i want to use my computer and i can not change any settings like the logo or the date in the bios settings.

The only way I can get this machine to boot is to clear CMOS. Once I've done this, it boots, takes me into the BIOS to save CMOS information and then it continues to boot into Windows. I can the use it perfectly normally. If I shut it down, then it won't boot, until I clear CMOS, then it behaves perfectly again.

I have tired an updated BIOS already, even tho i ahve 2GB RAM, i have tried using only 1GB i have tried using only 1 HDD, i have tired using the system to its bare min
altho i know that all other componantes are working fine as i used to use them on a P5N32
and the Graphics card, sound card, DVD drives, worked fine.
so i dont think thats the problem

I called ASUS tech support in USA, they said u should use one of the RAMs from the qualified vendors list, but when i ordered these 2 items i did ask the person if they were compatible and they said yes they were definataly compatible.

Clearly your motherboard is faulty in some way, try clearing your CMOS, then booting with a livecd containing memtest86+, leave it running for an hour or two and see if any errors present themselves, if you can use some ram from another machine or from a friend, do that and see if memtest still turns up errors. Chances are good that you have a bad motherboard though, and you'll need to RMA it.

Make sure the RAM voltage is set correctly for your sticks, many boards default to 1.8 and that could explain the crash on reboot after you have set them up the first time.

As you have only just bought the mobo, if you believe it to be faulty, you should rma it to the vendor (as your contract is with them, and not Asus). Only if the vendor (scan, etc) tells you to send it back to the manufactor should you take this route, if you do so without the vendors explicit permission then you lose certain rights under the sales of goods act.

If you really have only just got it (ie within 7 working days), then I suggest you return it to the vendor under the DSR (distance selling regulations).
