Guys I want to ask you... is there any solution for me...

my evga gtx470 just bought 2 months ago... I've got problem...

My monitor turns black screen and hang. and I should hard reset my computer. All my tower light is on... and the fans are still working but I can't operate anything even my keyboard is not functional. I've never oced my hardware not even a hardware, I have tried to reinstall my OS, driver, clean installing driver... nothing works

it only happens in 2d mode and work... such as Browsing, watching videos, YM, winamp....

don't know how to fix it... any solution for me? or should I RMA my card?

my specs is:

AMD Phenom 4x 9950
ECS A790GXM-A
APOGEE PC7300 2 x 2gb
AOPEN Prima power AO700-12ALN 700watt

plz help me... if you know the solution tq

Try your card in different PC, if the same things happened then RMA your card...

I took a quick look and only found something like 15amps per rail ( 4 ). The first thing I would do is swap out cables. You may be drawing too much from "one"....... It's also not a very good one from the little bit I read. Scrimping in the PS area isn't a good thing especially when your putting in a higher end energy grubbing card like that. Those cards also get HOT. Try running with the case side off and/or running with a house fan blowing on it. The cards fan may not be running "fast" enough while the card is at idle ( surfing, etc. ) Try raising the fan speed ( manually ) to a steady clip and see what happens.

I live at country side so... I mean... It's hard to find someone that has system that will run my specs :( (

swap cable have been done... ~~ I don't really understand about the 15amps per rail (4) <=== don't how to get that.... is there any practice there?
Scrimping? I've never done that... ~~
I don't thing that my card run too hot... because when idle my card temp is 40 - 50c and when load 70c - 90c I mean many people got that with the preference heat sink and it's normal temp for GTX 470... my case temp is on 40c or something.. never got more than 40c... ~~

tell me how many 6-pin pci-e power connectors does it have?? form the pics on google they dont... but you do have a lot of ide connectors if any of your hdds use the ides make them use the pheripherl connectors for them and then buy 2 ide - pci-e 6pin converters .. and 700 watts is good enough.. just make sure you have the pci-e pwr connectors and i would exactly recommend using converters thouh if you dont have the connectors get a new pwr supply...

A reference GTX 470 will draw a maximum of 18 Amps from the +12 Volt rail(s).

You will need to use PCI-E power connectors from two of the four +12 Volt rails of your AOPEN PSU.

As I've posted above "A reference GTX 470 will draw a maximum of 18 Amps from the +12 Volt rail(s)."

Your AOPEN Prima Power AO700-12ALN provides 15 Amps on each of the four +12 Volt rails. Of course the AOPEN Prima Power AO700-12ALN is sufficient to run the GTX 470.

Have you downloaded the latest GeForce driver from NVIDIA's website and installed it?

2D mode consumes a lot less power than 3D mode.

i've already.... installed ... ~~ 260.99

don't know... as long as I have experienced the blackscreen only occurs on 2d mode... from browsing to watching videos... or even on desktop without doing anything... never have one while playing games

Everything is fine... even I've furmark without any problem... it only happens while running on 2d application / desktop...

installing newer driver... even roll it back to the older...

I'm using win7 64bit ultimate..

tried to disable, uninstall the HD audio driver... even uninstall realtek sound driver.. and use windows sound driver... ~~ then change the older version of network driver... (some people say it may be an IRC conflict... but nothing is fixed ~~

BTW thanks for answering... and trying to help me :) ) btw maybe do you have a friends who have solved this issue?

@malmental: Let me make it clear... ~~ I mean... when I'm working in 2d mode... such as browsing, watching video (avi, mp4, etc), YM, mp3 (winamp, etc) or even just idle on desktop... I will get random blackscreen, when the screen goes black I can't interact with my computer... and I should hard reboot... (it's really at random states it can be twice a day, once a week, or even twice a week...) but it never happens when I am playing game such as Crysis, DMC4, etc ... don't know about 2d games because I don't play any or even have any game house...

The truth it never happens (the blackscreen) when it is on heavy load

I also suffer from this black screen issue. This happens to me "occasionally" and it seems to occur when the gpu core clock changes from 608 to 405 mhz. As for trying my gtx 470 in a different machine - my old system was a core2duo build. I had a gtx 260 that ran perfectly, then I bought the gtx 470 and got this problem. A couple of months later a did a new i7 build - everything except peripherals (including new corsair 850 hx psu)was upgraded. I still get the same problem. Absolutely no crashes during benchmarking, stress testing and gaming, just the occasional black screen freeze shortly after boot, or even more rarely, after exiting a game when the clocks reduce. This is why an RMA is waste of time because of the apparent randomness of the thing. :wallbash:

    I read a review of 2D performance over at Tom's, where 2D is crap on the GTX 460. ATI was called out on it, and they didn't have an answer, but the new drivers were forthcoming... Maybe some knows this review? My browser is getting ready to crash, or I'd look for a link...

    try the beta drivers... the gtx 470 is a pci-e 2.0 card thats backward compatible with pci-1.0...
    so the pci slot is not a prob.. but i would blame either psu or mobo i have had similer problems but that was on win 7 im using xp now... ( i have a gtx 460)
    mostly the mobo .. give it over to the computer shops and ask them to test the psu and mobo
