Hey Guys I've posted my problem on the Nvidia site but got no proper response so I was wondering if anybody else has this card and has managed to solve the problem. It goes a little something like this.....

My problem is that my PC as off the other day will not boot up passed the xp logo when graphics card is enabled, the screen just goes blank and says no signal output. It can boot up fine in safe mode, and in normal mode (if I disable the graphics drivers in safe mode), but as soon as I enable the card the screen goes blank and gives me the same error.

Everything was working fine until the other day

I've already tried, re-installing boot drivers, windows, graphics driver uninstalled updated, updated BIOS and checked leads connectors.

My specs are

AMD (San Diego) Athlon 64bit 4000+ 939pin 1mb L2cache
Nvidia Geforce 7950GX2
ASUS A8N-SLI Premium skt939 nForce4
Hiper 580W Type-M Black PSU - SLI Certified with APFC
2gb RAM
SATA 80GB drive

Any ideas peeps? If not am gonna send the bad boy back as its still under warranty.

Thanks for any posts,

Karliki

First of all, nice system spec. Anyway, if you can go in too safe mode, then I think the card itself is still working. Try a clean uninstall graphic card driver from the control panel, then add or remove programs (I'm sure you know this already), uninstall the driver then reboot then install a fresh new driver from nvidia.

It also sound like the refresh rate and resolution were set to high for your monitor, I know it sound stupid but happen to me once. You didn't say what monitor you're using, um,..apart from that can't really think off anything. Maybe it is a serious fault with the card itself.

is not true that if the system starts in safe mode the graphic card is ok as in safe mode the graphic card driver are not loaded.
Think the problem is video card defective.
Try unplugging/plugging it again and if same problem and you have another video card try with it.
Anyway in my opinion the card is defective

There's a discussion here and here about what seems to be the same issue.

But, being that those are your posts, it's not really helpful.

I ran into one tid bit that might be pertinent:

"Is the SLI selector card, the thing between the two x16 PCI-E slots, in SLI mode?

If so, try the other side/mode. Also, try a different PCI-E slot."

Thanks for the replies, I've tried the clean install of drivers (twice), tried with both new and old graphics drivers. I've also updated my BIOS, took the card out and changed placed in another PCI-E slot. This is really frustrating, I'm of the mind that something has gone pop in the card and that's why its not running, in which case it will be back off to my friends at ebuyer.com.

Thanks for suggestions guys, if anyone else has any ideas then post away :0)

what type of monitor are you using ?

Sorry, missed that in the first post.

I take it you are certain you did nothing to change your setup/configuration right before the problem started?

No BIOS changes?

No power options changes?

What's the native resolution of your LCD and have you changed the refresh rate from the LCD's default? <assuming you have LCD monitor>

Problem Example:

Quote:

I just added a LCD screen with 1280x1204 res, I played BF@ fine the first time I tryed it out, but when I changed the hrz from 60 to 75 (which looks much better) now on all my 3d games the screen goes blank (but I can still hear the sound) and then a signal not detected comes up, I have tryed to take the refresh rate back down but it seem's as tho it dose not make a diffrance. also I have a 6200 nvida and when I first played the bf2 the comp was not in pc mode it was in tv mode on the LCD but I been going through hell trying to get it back even though that mode truely is not worth it.

If not, I'm afraid it's looking like a component failure if we can rule out human interference.

And if so, what's failed: the motherboard, power supply, or the graphics system?

But, before we go in that direction: is everything seated properly? Cable connections? Motherboard isolated from the chassis, etc?

It's possible a "loose" situation could have caused your system to fail at this point after it had been working and hopefully the circuit protection is keeping you from accidentally frying something in a permanent way.

the Monitor is a LCD Videoseven E17PS.

I changed no settings at all before the problem. I've tested all connectors, changed my leads and made sure that the card is sercurley fastened. I've also booted up with only the essential items plugged in but I still get the same problem.

This is why its so frustrating as normally when something goes wrong, I know that I've changed a setting etc but with this I know I've changed nothing.

*starts to cry*

Thanks again for all input

have u tried a different GPU ?

Karliki · Apr 12, 2007, 12:33 PM // 12:33

not yet as I don't own another one and everyone I know has either laptops or onboard graphics on there motherboard

I had this card up until a few months ago, and it is very temperamental little thing thats for sure (The whole sli-on-one-card is ropey' as hell if you ask me). I had often experienced 'blanking out' at Windows but fine operation in Safe mode also.
Let me run through a few things (not sure how much you know so forgive me if this appears condescending)...

When you installed the drivers (I also hope you used Driver Cleaner to remove the old ones completely) did you install them 'twice'? As in did you get 2 cards that needed installation.
You'll know for sure if you check your device manager. In there under Display adaptors you should see 2 NVIDIA GeForce 7950gx2's. If you only see one (and possible some other random crap) then that's your problem. If they have different driver versions (never seen this personally before, but it could be possible) then that is certainly not going to be good for your card.
Another possibility is power. If your power supply is faulty it may not be feeding the card(s) enough juice .When I had mine I used a crappy 500 watt thing for a while which would hang a few times at Windows on a cold start-up.

The only other thing I can think of is the setting of your 'sli' options after you install drivers. It shouldn't affect the card too much (should still load Windows) but you never know.

Hope this helps. It's a nice card for sure, but its quite particular about what conditions it likes to function in, so I can completely understand it working for a while then suddenly cutting out on you. It happened to me a few times also. G luck...

Are you using vista as well? Nvidia still doesn't have a fully working driver for SLI in vista yet.

Tachyon · Apr 12, 2007, 01:07 PM // 13:07

Have you tried plugging the monitor into the 2nd output connector?

Karliki · Apr 12, 2007, 01:26 PM // 13:26

Thanks for posts, ok now to the replies.

Frojack: Yep I did a clean uninstall of the drivers and installed them again, both drivers are installed twice, so under the Display adapters it shows 2 9750GX2's. Now since I get a no signal error the only way I can boot up outside safe mode is to disable one of the 9750gx2's, if I do this I can boot up normally but the card isn't fully working (if that makes sense). When I first got the card I had to change my power supply to a SLI approved one so I don't think thats the problem (I've also booted up with just bare essentials turned on and still same problem). I'll have ago with changing the sli options :0)

Etta: Nope I'm running XP, I know that Vista is causing a few problems at the minute for sli and Nvidia users but that's not effecting me.

Azagoth: Yep I've plugged my monitor into both the output connectors and same problem on both.

Thanks again guys for your continual input.

Tachyon · Apr 12, 2007, 01:51 PM // 13:51

Have you checked to see if the PCI-e power connector has become dislodged from the card. If it's not getting the power to run then that'll also give you the 'no signal' message.

I'm guessing the fan start up as it's powered directly through the PCI-e slot itself

frojack · Apr 12, 2007, 02:50 PM // 14:50

Hmm... Then I well and truly have no clue at all. Could be one of the cards is busted. The very fact you need to disable one screams faulty hardware.

Single card solutions for me from now on

...

Karliki · Apr 12, 2007, 03:10 PM // 15:10

Yeh the connectors in tight, I'm thinking its a hardware problem. I'll send it back to buyer and let them sort it.

Thanks for help guys.

Etta · Apr 12, 2007, 03:25 PM // 15:25

Yeah that's the best thing to do really, don't feel bad. I remember when my old gf5950 ultra stoped working after 3 weeks when I first got it ages ago. Good luck with the new card.

Karliki · Apr 12, 2007, 03:34 PM // 15:34

When I find out what there gonna do I'll let you guys know, thanks again for input
