Okay, my new system consists of:

ASUS P5K3 Deluxe WiF iP35 DDR3 Motherboard (http://forums.aria.co.uk/Products?search=MB7-ASUS-P5K3D)
Intel Core 2 Quad Q9300 2.5GHz (Retail 775) (http://forums.aria.co.uk/Products?search=CPUBX80580Q9300)
2 x Patriot 2GB PC3-10666 Viper Extreme Performance (2x1GB) (http://forums.aria.co.uk/Products?search=MEM-II800-PVS32G1333)
2 x Asus Extreme 8800GTX 768MB PCI-E (http://forums.aria.co.uk/Products?search=GCX-ASU-8800GTX)
2 x 500GB Seagate Barracuda SATA2 HD's
Tagan 700W Modular BZ Piperock Series (http://forums.aria.co.uk/Products?search=pow-TG700-BZ) PSU
Microsoft Windows Vista Home Premium 64 OEM (http://forums.aria.co.uk/Products?search=SOF-66I-00788)
Gigabyte 3D Aurora 570 (http://forums.aria.co.uk/Products?search=CSE-GZ-FA1CA-***) case.

I installed the PSU/Mobo/CPU/RAM, one of the 8800GTX's, the HD's and got a successful boot and proceeded to install Windows from the DVD.

It failed to install to the HD’s, as they had not been formatted so I used the RAID software to set them up as RAID 0 (I got to that by pressing ctrl+I on booting if I remember correctly).

On rebooting, the system will now not even go as far as the POST screen.
I've taken everything back to just the CPU, 1 strip of RAM (tried all the slots) and 1 graphics card (tried both) but the system refuses to do anything other than fire up the fans and the case/PSU lights.

I've also tried this on cardboard to rule out case shorting, I've reset the CMOS loads of times, swapped the CMOS battery, reseated the CPU and fan (which all looks okay and snug), sworn, even gone to work and tried to forget about it, but nothing I try now gets even as far as the POST screen.

I can get a series of beeps if I remove all RAM; there is no audio if I remove the CPU and a continual beep if the graphics card is not powered. Other than that, no clues as to what’s occurring at all.

Any advice that will avert an RMA will be gratefully recieved!


Thanks in advance.

Have you tried using another graphics card or a friends graphics card ? Are you sure your CPU heat sink is seated correctly (i had a problem with a pc posting once and it was down to this)

Why are you running 2 GF cards in a crossfire board? Or are you using over two monitors?

yes , you cannot use SLI on a p35 mobo , so one gfx card will be rendered useless

You can, but only if you have a GX2 card ;)

I've tried with two graphics cards and installed the CPU/heatsink several times (seems very secure and even).

I've also now just tried a different PSU and that's made no difference either. :(

Ok, have you tried a minimal boot? Ie just 1 stick of ram 1 Graphics card just the 2 power cables and the power switch connected NOTHING ELSE.

If that fails then try the same with the board removed from the case to ensure that it is not a grounding issue

Yep, tried and failed.

Correction, that should be three power cables!

Plug some speakers or headphones into the onboard souncard - ASUS boards speak to you...

Just been and tried that too, tried all the audio outputs including the cases one. Nothing more than a faint click as you put the jack plug in/remove power from the board.

Is this a feature on all boards as I couldn't find anything in the manual?

Have you checked the processor socket for bent pins?

Yep. Everything looks okay, superficially.

On the Asus forums, people with a similar problem have found it due to the processor not being supported by the factory bios revision. The ways around it seem to be putting an older, supported CPU in and hoping that works well enough to get as far as flashing the bios or removing the bios chip and sending it Asus for flashing. I'm tempted to get a cheap CPU to see what happens.

i was about to say cpu support but you have found it already, from what i have read no mobo ships(atm) that can support 45nm quads off the bat. they all need an older chip to flash and for most it is still a beta bios.

gl with it m8 and if you overclock it post your results for us too :D

Just popped out and got the cheapest (Celeron 440) CPU I could get.

Problem solved (well, I can get it to boot).

I think the CPU isn't supported by the BIOS (and I'm not sure it is one the lastest revision either looking at the Asus website). Either that or the CPU was dead, but it would be a bit strange if it were.

I'll keep you posted, thanks for all the replies!!!
