Hello,

I have all brand new:
- ASUS M4A79 Deluxe mobo
- Phenom II 940
- 8GB Corsair DDR2800
- Corsair 850W powers upply
- Diamond 4870X2 Video card
- 2 WD Velociraptors in RAID 0
- LG SATA DVD RW

80% of the times I reboot and/or shut off & power back on it starts to post, I hear the beep, but then just hangs on black screen & does not post any further. It is right before I see Motherboard Splash screen.

It happens at random, but over all most of the times. The few % of times it does work it does boot into Windows fine.

- Everything is out of the case on Foam
- I tried re-setting CMOS
- I updated to latest BIOS
- I tried different power supply (1200W)
- I tried with only 4GB Memory
- I tired Memory in different slots
- the CPU is not Overclocked
- I tried resetting CPU
- I tried re-applying Thermal paste
- I tried Video card in different PCIE slot
- I tried with No DVD RW & NO HDs plugged in

Is their something else I can try to solve this problem, is the motherboard bad

Any help would be greatly appreciated.

Thank you,
Jeff

Hey, Janteby
The first thing I can think of is that you may not be running enough voltage to your memory. My M3A79-T defaults to 1.8v if I clear the CMOS. So check to see what your Corsairs are rated at. Go in and manually set the voltage to their specs.

Hello,

Thank you for the reply

Sorry I already tried that too, anyway the Corsair Mem voltage is 1.8V

Any other suggestions ?

Thank you

Kind of a shot in the dark here, as I don't do the Raid thing but I wonder if manually setting the harddrive to master overriding the cable select might make a difference?

Thnx again but

"- I tried with No DVD RW & NO HDs plugged in "

Any way HDs are SATA so that wouldnt matter

Anybody else ?

What is your exact model of Corsair memory?

A lot of Corsair memory needs more than the "standard" 1.8 volts. How do you know that 1.8 volts is the voltage is supposed to be?

In the short term at least, try setting your mem voltage to 2.0 volts or +.2 if your BIOS sets it that way just to see what happens.

Hello,

Thank you for the reply

The exact Model of Memory is

CORSAIR XMS2 4GB (2 x 2GB) 240-Pin SDRAM DDR2 800 (PC2 6400)

TWIN2X4096-6400C5DHX

5-5-5-18

It states right on the Memory itself 1.8v

I tried what you said, increased to 2v & still same problem. The 1st 2 times I rebooted it booted up normally but then now again it just hangs.

Any other suggestions ?

Thank you !

What OS?
Have you tried with 1 stick of ram and 1 hdd?

One buyer was quoted
"Other Thoughts: Had MAJOR issue's BSOD a lot, finaly found a patch for vista 64 to run BOTH sticks at once. I came close to giving up and calling Newegg, but the patch for OS was the problem not the product."

also exactly 1.84 volts

April 12, 2009 9:11:57 PM

Are you using the full 8 pin power connection on the motherboard or did you leave that little black cap on and only connect a 4 pin here? Board will not boot without the complete 8 pin connection and 24 pin connection being used.
April 12, 2009 9:20:07 PM

Hello,

Thank you for the reply

The OS isnt the issue at all because I am not getting BSOD & It hangs on post before Mobo splash screen

Also I mentioned above I tired with No HDs & same issue & I did try with 1 stick of memory too & same issue...

I just tried 1.84v specifically & even tried with different brand, Patriot memory & still same issue :-(

Any other suggestions ?

Thank you,

Hello,

Thank you for the reply

Yes I always use the 8pin connector anyway.

Any other suggestions ?

I was having a problem with this type of hang-up or freeze with a m4n72-e and the problem was the video card. The video card is one of the first things that kick on and if there are problems with it, the comp can freeze anywhere in the startup or booting of bios or windows . Run 3dmark06 and furmark. If the comp locks during these tests, swap out and try another video card. run 3dmark06 a couple of times even it it works sometimes a lock up of this program points to the video card or just swap it out and see what happens.

Hello,

Yes ! that was it ! If I changed the video card all is ok now.

Thank you bpnbm.

Just out of curiosity, what video card did you have that was causing the issues ?
Mine was the Diamond 4870X2.

Off to return it now....

Thank you !

I was using a XFX 8600GTS which is in the process of being sent back for a repair or replacement. I had found your post because I also switched my mobo to the M4A79 Deluxe, and so far is much better than the M4N72-E. Glad I could help.

that's exactly what i was going to guess, the video card.

that system should be rock solid.

which video card does it work good with ?

I'm now running a evga9800 gtx. Was thinking about the 260 but the amp's it needed was right on the threshold of my psu.

Unfortunatly, unless you have a nVidia chipset you won't be able to use SLI/nVidia graphics cards.

If your motherboard has the AMD/Radeon chipset, then Crossfire is the only option.

Thanks for the help...well...guess I'm stuck with the cards...

Do you know where I could get good(and what is good) cards for not too much money... spent alot already getting these two.

And was thinking of updating my bios...if that is a good idea.

would appreciate the help..

Thanks again...

It's always a good idea to have a updated bios.

If i were in your shoes I'd look for a good nVidia/ SLI board ... It would be cheaper than replacing 2 graphics cards. But that's just me.
Amd does make nVidia motherboards(chipsets) . So maybe check the prices and see what you can find.

This one is comparable might be what your looking for.

Hope that helps.
April 24, 2009 8:54:28 PM

thanks..will maybe do that...seems such a shame..but well...this is how it goes.

thanks again...

I'm sure you will be able to compensate with the resale of your mobo :)  It's a rather popular one and you'll have the next best thing. All in all you and the someone else will win and be happy!

I had the same issue with my XFX 8600, glad you got it working now. If it wasn't your card you may have wanted to check out the power source. If you still have any issues trying putting a UPS between your system and your outlet to see if it's bad power.
