Video Card Help Please!...Update!

[hennessy1]

I have an evga gtx 480 installed with both the latest drivers and the 197 drivers. With both once booted into windows on the desktop there is screen artifacts. This happens with basic and aero desktop modes. There is none with the drivers uninstalled. I tried to do a screen shot of it but it didn't show up.

I was able to make a video on my phone of it sorry for the poor quality.

It's too strange!

Try to use the third-part tool for uninstalling such as Revo Uninstaller, Revo Uninstaller and so on.

Try with older more stable drivers? Newer doesn't always mean better.

 

[hennessy1]

Ya i did this on a clean install. Should i go back more then the 197's?

 

[CrystalKing]

No，it isn't able to be a good idea at all.

I think the newest one is Okay, it's designed by Nvidia for GTX400s, so it can offer the most excellent performance and stability.

But you should keep your OS clean before, make sure the old drivers had been complete uninstalled include regedit information.

I removed that card and put in a gtx 285 with the 257 drives and no problem at all would that indicate it is the card then?

 

[CrystalKing]

Don't exclude the possibility.

But I recommended to try it again before return the card for warranty.

Specs of the rest of your system please. Have you tried running any 3D applications (games) yet? What were the results?

I does look like it could be a card problem especially if your GTX285 worked on the same install but let's look at all the options before sending in for an RMA.

 

[hennessy1]

I have a 1.2kw psu. A e760 x58 motherboard. And 2 raptors in raid 0. I also had a 5870 installed with no problems before this card.

Ok you are more than set then. Things I would do:

1. Remove any overclock and run hardware at speced voltages and timings
2. Clean PCI-E slot and card connector and reseat the card.
3. Run stress testing - Furmark/ Vantage/ Crysis demo loop and check for artifacting/ crashes etc. If it does swap in your GTX285 without changing the driver and rerun the test confirming that the card does work. If it does RMA your GTX480 as faulty.

If the GTX480 works in 3D applications but still has artifacts on the desktop then try both DVI outputs and change the DVI cable you are using.

If none of this works... looks like you will have to RMA as a faulty card. As a last resort you might want to try forcing a higher clock speed to the card at the desktop and see what happens but this is not an ideal solution anyway.

Well I cleaned out the pci-e slot and removed the driver through safe mode without then with driversweeper. I reinstalled a newly downloaded copy of the 257 driver restarted and before I could even sign into windows the screen started artifacting. Way worse then before with lines going through it.

Would that mean that there definitely is a problem with this card. I opened IE and then it started again any video or pictures on the screen cause it to do this because I opened up msn.com.

Sorry but it's time for an RMA. At least EVGA are excellent with their service. Good luck!

 

[hennessy1]

Damn that sucks. Well thanks everyone for you help I really appreciate it.

Well I replaced the card with a new one and same issue happend. I messed around with the resolution and refresh rate. When I change it from 1080p to 1080i with 30Hz the issue goes away but the picture looks like shit and there is over scan.

What can be causing that issue. I tried just an hdmi cable and another dvi cable but once it gets past the starting windows screen it says mode not supported on the tv. I have my current setup going from my pc to a hdmi switch then to the hdmi port on the tv. The model is Samsung LN52A650. I tried connecting the other dvi to hdmi cable right to the tv and same message.

I just tested it on this pc monitor
http://www.newegg.com/Product/Produc...82E16824254043

and change the setting in the nv control panel from pc monitor to tv and everything when fine. So how do I go about fixing this?

Update: So I remembered when I had a viewsonic and my nvidia card always overscanned it and messed up the picture. I went to find the edid setting for my samsung tv and did the following:

After the exe extracts the files I went into NV_Disp.inf and removed the following entries

HKR,,OverrideEdidFlags0
HKR,,OverrideEdidFlags1
HKR,,OverrideEdidFlags2
HKR,,OverrideEdidFlags3
HKR,,OverrideEdidFlags4

Those entries can be found under the [nv_clearRegistrySwitches_delreg] section

I then added my edid for the samsung monitor which comes out to this string

HKR,, OverrideEdidFlags0, %REG_BINARY%, 4c,2d,57,03,00,00,FF,FF,04,00,00,00,7E,01,00

The first 4 byes 4c,2d,57,03 is my monitor and is what should be replaced.

I added that string to this section
[nv_commonDisplayModes_addreg]

Saved the file then ran the setup installed and restarted. Everything came out fine no more issues so far atleast. Only question I have now is when I go to my nvidia control panel it only lists PC resolutions does that mean it effectively thinks this is a pc monitor now instead of a tv? If so that shouldnt effect gameplay?
