New Asus P5B Deluxe is a non booter? Anyone observe this behavior?

[FragTek]

I just received and installed my new P5B Deluxe and I can not get it to POST.

Let's start with rig specs:

P5B Dlx 1.03G

E6600

2gb Corsair PC2-8500 (D9GMH)

7900GTO

3 x SATAII HD's

BFG 650w PSU

Vapochill LS

The first odd thing that I've noticed with the P5B is that it tries to boot up before my Vapo should be allowing. I have my Vapo set to boot at -25*c and about 5 seconds after the compressor kicks on the computer tries to boot and the Vapo didn't even send a boot signal?? At which point the Vapo then senses that the computer is "running" at an unsafe temp and does an emergency shutdown. I've tried all combinations of the power switch connector and I've concluded that it's definately not my wiring job causing this problem.

My fix for this was to disconnect the mobo power switch plug from the ChillControl board and let the Vapo hit a nice low temp of about -50*c and then connect the plug to the ChillControl and have it trigger the mobo to boot up the computer.

Once the board receives the signal all of my fans spin up, my case lights come on, the optical drives all turn on and the Asus logo on the board has the red backlight come on but nothing at all happens from there on out. I get no beeps whatsoever, nothing on the monitor.

I've tried clearing the CMOS, taking out the CMOS battery and waiting a bit, disconnecting the main power cable and doing a CMOS/battery clear, reseat the video card (which I have to take out to clear the CMOS, who's genious idea was it to put the reset jumper and battery in an inaccesible area when the vid card is installed????), reseat the RAM, try a single stick of RAM, reconnect floppy and IDE cables, reconnect power cables. I'm still getting nothing.

So the question is: is there a workaround, a quickfix, or do I have a DOA mobo?

Thx in advance.

On my last SLI mobo the top pciX slot wouldnt boot but if I put the card in the lower slot It would boot.

I have an aftermarket cooler on my SB which doesnt allow for a vid card to be mounted there

Probably ram requires more voltage then the stock bios ships with.

 

[FragTek]

Thx 4 suggestion but I think my AW9D shipped at the same voltage and it was able to POST fine with my RAM.

Could this be anythign to do with the funky way that the P5B powers on? On my P5B when you press the power button the pc switches on, then switches off, then switches back on again. Its some kind of overclocking feature afaik but it seems to mess things up

My board started doing exactly the same thing when i put it under a pelt. I eventually traced it down to the CPU not making proper contact with the LGA pins due to too much grease in the socket. I cleaned all the grease out, applied a very thin layer of grease instead, and it started working again.

Yea mine does that after being disconnected from the power for a long time such as after transporting to a lan etc.

I dont no anything about sub zero cooling im afraid likewise with water

 

[FragTek]

Hrmmm thanks guys. Got some good tips here and from XS that I'm going to try later on.

@XMS: I don't grease up my socket but I do plan on taking the CPU back out today and checking to make sure that all of the sockets pins look ok and then try booting without a CPU to see what happens.

I'm also going to try loosening up my vapo board mounting kit a bit, people have said that if you crank it down too hard it will stop the mobo from working and sometimes even kill it, so hopefully that didn't happen

On another note when I took the board mounting kit off of my AW9D there was mad condensation on the back of the board directly under the socket... Wondering if that's what ended up foobarring my board so it wouldnt clock like it used too? Needless to say I got an extra piece of neoprene and put it in there so hopefully that wont happen again.

Cheers fellas.

Mate, aint that just a recipe for disaster???

Nope, I had no condensation in my socket nor any pin rot what so ever when I took everything off of the AW9D. The Vapo just isn't powerful enough to need it on an LGA setup.

IMO if you're taking something below ambient then its better to be safe than sorry and just spend a little time greasing stuff up to keep the air out.

No CPU socket is air tight and with that massive gap around the caps in the middle of the CPU u'd be mad to not at least insulate that bit.

 

[NickS]

Yeah, you definitely need to grease up.

 

[FarFarAway]

Agreed on the grease up

And the P5B series is very funky when starting up, try a BIOS flash that seemed a little better to me

 

[NoL]

As for pin corrosion, takes about 2 months. And it always happens if you dont use grease.

 

[NickS]

Get ready to get slippery, Frag :rollingla

 

[FragTek]

Meh, sounds pointless after running a few months without any corrosion or condensation in the socket on my last setup, but if you say so.

 

[FarFarAway]

There's always that *one* time when it happens...man you wouldn't be happy

 

[FragTek]

Got it workin'!!! Guy on XS told me that his wouldnt boot with any internal USB's plugged in, so I unplugged all of em and voila, booted right up. Crazyness!

 

[markkleb]

Glad its up and running...And glad you shared the solution with us.

 

[FragTek]

Well its dead again... And this time it really feels DEAD. I can't even get it to kick on the fans/lights, etc. Much less begin the POST process.
