New Computer - Display Problem! (DFI mobo, Geforce 6800)

thanks marvin! i read your post before and didnt have a chance to reply.

here is what I just posted at DFI-street:

i just got home with a temporary PSU and vidcard...installed them, tried each individually...utter failure.

first i tried using a basic PCI (not PCIe) GeForce 5500 vidcard...no dice, no video showed up on my monitor.

Then, I swapped my Seasonic PSU for an Antec NeoPower 480...only, it was an open box an apparently the last craphead who had it stole all of the cables, luckily the 24 pin and the separate 4 pin (12v) are hardwired to the PSU. Anyway, although i knew it would fail since not all 4 connectors were present, I tried firing up the computer with the CPU, vidcard (tried both the new one and my 6800), and 1 stick of RAM. Like with the Seasonic, if I have that 4pin plugged in to that 12v slot, it wont power on at all. However, if I only use the 24pin plugged into the mobo w/o that 4pin, the mobo fired up, fans spun....but still, no video.

So...my worry is now is my DFI Ultra-D the problem?
Could that 4pin, 12V receptical on my mobo be defective?

Should I RMA it for a replacement from Newegg and see if that helps?


any thoughts?

When you connect the 12V aux, do the board LEDs turn off? That'd be a quick indicator that the board is bad. Either way, I'd definately RMA the motherboard.

If you have a Fry's or another decent computer parts store nearby, I'd just buy the DFI mobo from them to test out everything else. If it worked, I'd RMA the defective mobo to Newegg and eat the 15% return charge.

When I bought parts for my computer, I got everything but the motherboard from Newegg. Motherboards are really too finicky to deal with an online vendor. Especially since you often have to reflash the bios to the newest revision right after you buy it. Shipping wastes too much time if something goes wrong, and bios flashes go bad way too often.

I don't know that I'd agree with this. I've been through a bunch of mobos from Newegg&friends, and have yet to have a problem I couldn't solve on my own. My current DFI NF3 board needed to be flashed, as you said, but I don't think that in itself is a reason not to buy online, esp. considering how much can be saved. Heck I've even bought refub mobos from Newegg that turned out great. Worst mobo experiences I've had were a Shuttle KT266A that died after about 6 months (that's what I get for trying a cheap board), and a POS Epox 8RDA+ that died after about two years due to bad caps, and took a CPU with it.

Well, if you have a Fry's Electronics nearby, the price difference between them and Newegg is usually within $20 after tax. Sometimes Fry's is even cheaper than Newegg, especially with their combo deals. Only problem is that selection isn't as good, but all the big hitters are usually there.

Not having to move a defective board back and forth through the mail system, and being able to return the board for random incompatibilities without the 15% restocking is worth that.

thanks Marvin, ID,

can I state that I am really hating this PC building process. funny, someone just told me that the PCs they build for others have no probs, but the ones they build for themselves are just plain problematic. well, same for me.

after a hellish ordeal last night trying to make things work, including using a PSU i picked up from Bestbuy just to make sure my Seasonic wasnt the issue, and cutting up my hands on my damnable Scythe Ninja, I am sending back the DFI mobo to Newegg for a replacement.

My CPU might be the problem, but i have no clue. I might have to RMA that too

sigh. i'll update this tonight or tomorrow i hope.

oh, and I am pissed at Antec since the door on my P180 (black) snapped off last night. great.

Heh, I know what you mean. My current computer had it's fair share of toothing problems.

First motherboard I got, a Jetway, died on bios flash because Jetway had the wrong bios at it's website.

After I exchanged it, I noticed that it was incompatible with the X-fi and wouldn't boot... So it went back in favor of the DFI.

And watercooling it was a pain in the ass. I mistook the pump intake for output and managed to spill a bunch of antifreeze on my carpet because of that. After I got that fixed, did a 24 hour leak test and everything looked good. I go to hook up everything, start playing BF2, and suddenly computer crashes. Open up the case to find that my CPU hose fittings are leaking onto my 7800GT.

Stupid plastic hose clamps. Luckily, everything still worked fine after a lot of cleaning and drying.

I'm sure it'll work out fine. Eventually at least.

Hey there M8,
DFI Mobos can be a bit tricky, it dosent sounds to me like the CPU or VGA Card are bad. its more like PSU or Motherboard.
Have you tried a PCI videocard ? just ot check, it can sometimes be usefull.
BTW I think you have to connect the 4 pin, cuse its the 12V that feeds the CPU, without it the PC wont boot I think. Try to do a bios reset. that Might help.
then try to pullingout the critical Devies, like the Memory and the Video Card, and see if the Peakers beeps, if it beeps that it means the problem is in a device that he iis les important, if it dosent beeps, it means the CPU or MOBO is bad. as far as my experience, You can contact me in my MSN/ICQ if you want further Help.
Good luck !

thanks guys!

ive posted diff posts in diff forums and emails, so i think i keep getting mixed up what I have posted where. So ill just retype it here.

I have tried 3 different PSUs on my DFI mobo: w/ all 3, whenever I plugged in that 4pin 12V CPU connector, the mobo would NOT power up. With any of the others it was fine, but if that 4pin was plugged in, nada, nothing would poweron.

I did try a plain old PCI vid card (using 2 diff PSUs as well), and still got no video output to my monitor.

I tried reseating the PSU, w/ and w/o RAM plugged in: didn't make a difference.

For the most part, and definitely for the last several days, I have only had the following connected to my mobo:
AMD 3500+ Venice core
1 stick (512) of pqi Turbo RAM (see 1st post for details)
PSU (as stated, in various combinations of 24 pin, 4pin, 4pin molex, and FDD connectors)
Leaktek PX6800TDH vid card (and for a short time, a PCI Geforce 5500)

I have left the optical drive and Raptor off of the system for now.

Shadow, I'm not sure what you mean by "Peakers." Y'know, despite my enabling the speaker on the mobo, my system has not even once beeped. I think this actually might be common among DFI users, from what I recall reading at DFI-street.
(btw, thanks for the offer, I might end up contacting you for more help)

again, thanks for the pointers folks. VERY much appreciated. i'll be back with more

Sorry m8, Quote:

I meant Speaker, you know, the little things that beeps :-)
Anyway, the more info you give only makes me think even more that your Mobo is DOA (Dead On Arrival) and he is the one making all the trouble. If you cannot change the MOBO right now, try using all your parts in another sytem (s939 of course ) that you know that is working properly !, try switching one part at a time: like CPU, then Memory and so on. anyway i think you should RMA your Board if you havent did so allready. If it didnt BEEPED even if you pulled out the Video Card and/or the Memory and/or CPU then I am 99% sure it is the Mobo ****ed up.
Anyway keep us Informed, and feel free to contact me via MSN/ICQ !
Good luck bro..

Update:

I RMA'd the DFi board, got a brand new replacement a day or so ago. The CPU is currently out on RMA and probably won't come back til the end of this week.

I just tried the mobo with 1 stick of RAM and all 4 power connectors plugged into the mobo (24 pin, 4pin for CPU, molex, and small FDD type). Again, NO CPU was plugged in. After I got it to power on, I turned it off, and plugged my vid card in. However, NO video is showing up on my monitor. Then, I pulled out that vid card and tried a different, brand new vid card. Still, no video.

Unlike before, the mobo will power on with all the proper power connectors plugged in, which is good! My guess is that the other mobo was bad.

But what I don't get is why am I not getting any video output?

Shouldnt I at least see the BIOS, even without a CPU plugged in?

Again, I am clueless. Any help would be so very appreciated. Thanks guys.

Do you have your on board speaker on? The one that gives the beep codes? This can address some of the problems
I have the same board and have built many others. I have not read all the help post that others have written.. but you can go to http://www.dfi-street.com/forum/index.php..Much help there. When you get all your parts..give me a scream and I can walk you thru it..this is a very solid board, not many RMA's. It generally is the little things that screw it up.

Sorry just read a buch of othe posts..I have repeated many other suggestions
What slot is your ram in? With one stick it should be in the orange slot farthest away from the cpu..it will not boot if it is not in that slot.
 
Oct 23, 2005 at 2:45 AM Post #30 of 31
hey sdgserv, thanks for the ideas.

the ram is in slot 2, the one that you mentioned. that's is part of why im so confused. I believe ive done everything necessary for the board to boot/post/whatever it's called.

i will enable the board speaker, and see if i get any sort of result.

thanks, and do keep the help coming
biggrin.gif


**EDIT:
according to a mod a DFIstreet:
"The rig will not pass the POST without a CPU so there's no way you can see video."

so I guess I'll just be waiting til the 3500+ is back...
