Hi-
 
I built a rig @ the end of November.  Put in a eVGA GTX 670 (2GB) and all was well.  Then around Christmas I started getting Red or Green lines in the display.  I RMA'd the GTX 670 thinking the card was faulty.  I got a GTX 680 as the replacement - nice upgrade.  But I've still got the same problem with the replacement card.  So - trying to really work this out - I RMA'd the Asus MB and still have the same problem.
 
Most of the time it boots to 800x600 and can't detect the card type at all.  I've gone through safemode - removed added it, cleaned the drivers - etc.
 
But the real kicker is that I don't think it's windows at all....as I get the Green lines in the BIOS post screen as well as the BIOS setup screen.  Windows isn't even running!  It's really unusable.  I've replaced everything but the RAM, CPU and PSU.  But in replacing both the card and motherboard - I'm shocked I've still got the same problem.
 
Asus P8Z77-V Pro
Intel i7-3770k
GSKill 2x8GB DDR3 1600Mhz RAM
eVGA GTX 680
Seasonic 750W PSU
 
Could the problem be with the power supply?  It has the correct 2x4pin connectors for the end of the GTX card.  And like I said - I never had a problem for the first month I had the system.  Unfortunately - I don't have anything else I can swap components like this with.  A couple of 5-6 year old Dell Optiplexes laying around doesn't help with troubleshooting.

The Seasonic PSU that I've got only has the one 8-pin connector to the side of the PSU that splits out to the 2x4pin separate connectors.  I just have one set.  I wish I had another PSU to swap out - but I'm losing faith that anything I can do will fix it after already doing 2 RMAs for different components.
Thanks.

Please look on the back of your powersupply and post the -exact- model number
 
The GTX 680 -requires- (2) 6pin PCIE connectors
 
Your description of (2) 4pin connectors, would appear to imply your have not connected the power to the videocard correctly.
 
This would result in -exactly- the problems you are having

Is this your PSU?

Hello toddac10, 

Welcome to the forums. I do apologize for the inconvenience and issues you are having with your replacement card. I assure you we are here to assist you. If you are getting artifacts during post it may likely be isolated to the card specifically. If you like we can assist you with another replacement and request a 24hr burn in test before shipping it out to you. If you have any concerns or further questions please do not hesitate to contact Tech Support 24/7 888-881-3842.

Regards

Thanks for your response.  I would be interested in getting another card and this time have someone do a 24-hour burn in.  I think the chances of having 2 bad cards is pretty rare - but possible.  Do I need to go through the normal RMA process again or how do I RMA a card for the "second" time?

The picture from NewEgg shows a bit diff connector layout than what I've got.  However the model # all matches up.  Not sure if Newegg has the right picture or an outdated one.
 
The PSU has two 12-pin connectors labeled for PCI-E use.  I've tried the cable in both.
 
My PSU does NOT have a "normal or hybrid" switch on the inside.  Just the normal I/O switch on the back.
 
I took some pics to help show what's going on.
 
This one shows what the display looks like with the green lines.

Did you also replace your dvi/hdmi connector and try another monitor as well?

Well, I went all the way.  I'm at my office and went down the hallway, grabbed a brand new Dell P2412H monitor out of the box, literally, and plugged in all new cables from the shipping box and cabled up DVI.
 
Still get the same green artifacts as shown in on of the pics above.

Here is a shot of the BIOS screen with the new monitor.  I can't even see all of the setup information.  Resolution is stuck @ 800x600 it looks like.
 

 
I have removed the video card and connected up to the DVI on the motherboard via the Intel HD 4000 that is built into the i7-3770k - but I don't have another nice PCI-E card to put in.   Everything here @ my office is really an old desktop or laptops w/docking stations.  I wish I had another similar card to try it out - just don't have the $400-$500 for that luxury... 
 

It's either your CPU's IGP interfering or a defective card. Disable IGP and try again or test the card in another machine to see if you can replicate the issue.

Hello toddac10,

I had left a message on  your voice mail in regards to setting up another RMA and a 24hr burn in test on your replacement.  If you have any concerns or further questions you may email me directly or contact Tech Support 24/7 888-881-3842.

Regards,

Hey James-
 
Can you PM me the info on the RMA?  I can't send you a PM since I don't have enough posts.  I'm just curious as to the timing of when to expect the replacement card and when the burn-in test will be done.
 
Thanks,

Hello toddac10,

You should have already received an approval email in regards to your RMA If not I have resent the info to your email address. You can also see the information/status by logging into your account clicking on member home > my products > view details on the gtx 680. 

Regards,

 
Hey there JamesL-
 
Can you check on the burn-in status and the RMA?  I logged on to my account and it shows that EVGA has received the 2nd card - the GTX 680 as of yesterday 2/18.  Shipping status for the new card says pending.  Have they done the burn in yet - or is it being done now?  I'd like to get this before the weekend - is that possible?
 
thx
 
(still can't PM - more than 10 posts, member longer than 5 days....'Sup?)

I do love EVGA's CS. My next card will definitely be a EVGA. Is it possible to SLI this MSI 660Ti with a EVGA 660Ti? (As long as they are both the 2GB model).

My screen looks EXACTLY the same as your screen.  Is the issue a faulty video card?

It looks like the VRAM has failed on your video card. Time to apply for an RMA replacement.
