Help - DFI EXPERT no video on boot!

[Vassili Zaitsev]

Stupid question, did you try use your graphic card into the second PCI-Express slot?

It worked for my non-booting rig.

 

I dont know what kind of strange reason can make this thing dont works on the first slot.

 

 

*make sure you have the four power connectors plugged in

[Dudeygeezer]

ok ill try the second slot, i will lose my audigy sound card which is something i didnt want but its worth a try just to see if that works...

 

 

if that is the case doesnt that mean that the board is faulty anyway??

[Dudeygeezer]

well.. it didnt work, didnt really do anything different either.. still behaved the same..

 

 

how do i rma a board or at least get to talk to a dfi rep?

[Dudeygeezer]

anyone else think of anything i can do? should i try a new bios or just fill in the rma form?

[Dudeygeezer]

i have tried to unplug everything but the essentials but that makes no difference...

 

any ideas why it still acts the same when i have no power going to the card or pci express bit so its only being powered by the slot.. it works fine when i just do the quick re-turn on thing..

 

oh and this is what i really have..

 

3700 sandiego

2x1gb ocz pc4000

512mb 7800 gtx

soundblaster audigy

DDen 12v pump 2x120mm fans @1400rpm cooling the 120mm rad hmm this does start when the sys does.. ill unplugg it and see if thats pulling too much to start up the sys, it will be ok for a second

dvd rewriter

cd rewriter

37gb raptor

40 gig maxtor

120gb seagate (storage)

3x80mm case fans

1x cold cathode uv light

Aerogate II - for fan control -- hmm could be this too ill unplug that

2x 60mm fans blowing on memory slots

i think thats the lot

 

but when i tested with bare bones i only had

cpu

mem

GTX

pump + 2x120mm fans

aerogate

the rest was unplugged

i will now test without the pump being powered by the psu... maybe it drains too much on start but when the sys is going ( pump still going and i turn off and on again quick that low spike isnt there cos pump hasnt stopped spinning - good idea but i will check)

 

EDIT:

ok i tried it

NO pump no fans no aerogate no hdds damn this thing was quiet lol

 

it made no difference.. i even turned the voltage rails up to silly numbers waiting for a pop but it still acted the same

 

BUT one thing i was able to notice because the thing was now so quiet was when i boot from off i get no video but the gtx's fan is spinning rather loud! enuff for me to hear it (maybe flat out) and when i quickly off and on it the system was much quieter.. i checked the gtx's fan and it is running slow no risk of cutting my fingers off like that.. - but this is when the damn thing is working!!

 

so gtx fan speed hi on first boot from off and no video

do the quick off then on thing

gtx fan spins slowly (quiet but i get video and can use the system all day with no hiccups

 

ive even checked the temperature of the gtx and its not going near 55 degrees and idles on desktop @ 40, there is a bit about have max fan speed all time which is ticked but this is windows software not the boot sequence...

 

hmm.. what ya recon now?

Have you tried a different video card? Even an old pci card, anything? I would want to try to find out if it was, in fact, the mobo or vid card. If you put in an old pci, super basic vid card and it still won't boot without jumping through hoops, then I would say you can rule out the vid card as the problem. It would be even better if you had access to a pci-e card that didn't require as much power as the gtx, say a 6600 or something.

Dudeygeezer start your rma process because I read the whole thread and you have tried the 512 thing in another computer and the 512er works. RMA the board.

 

RGone...

Did your rma'd board fix this issue? I just got the expert myself and I am having the exact same problem but with a 7800 gt. Just wanted to verify that your rma fixed it before I submit an rma myself.

[Thorgal]

I've had the exact same problem with my Ultra-D board. Right now I'm on an Expert board but your problem looks very recognisable.

 

No video on screen, but the computer did seem to take of (with a blank screen in standby).

 

I gave the board to a friend and he reprogrammed the bios chip from scratch, so I'll be trying in the next few days if this made any difference.

 

Oh yes : I did try to boot with a spare PCIe card, but still the same blank screen.

 

I'll keep y'all posted.

[Mathius]

This sounds like the exact problem I'm having. What exactly do you mean by reprogramming the bios chip, you don't mean flashing it do you?. Did this ever fix the problem?

For clear understanding : yes I mean reflashing it, but a friend of mine did this by removing the bioschip, erasing it completely first and then program the bios on it.

 

Unfortunately it didn't fix the problem. I had to RMA the board, because frankly, I didn't see any other way. I really wonder what went wrong, as the problem started occuring slowly. At first : no video once in a while, after a while half of the times, and now no video at all. Also : at first I could use the bottom slot as backup. In the end that refused too...

 

To be honest, and on a sidenote : my DFI expert board also has lots of inexplicable little problems. It works fine at stock, but OC'ing with it is imho a real nightmare. I've spent countless hours already trying to figure the board out, and frankly I'm sick of it. I've ordered a backup SLI-D that should arrive any day now, so I can get going again. I pray my Ultra-D comes out of RMA soon, then my Expert goes out of the door. ASAP.

 

PS : Sorry for the late reply.

[Mathius]

no problem

 

thank you
