I just installed 2 GTX 460's(SLI) into my computer. After installing the driver for the new video cards NOTHING works correctly!. I May have moved the sound card to a different PCI slot but that should be no biggy but I cant even detect the card anymore. When I run a game like BFBC2 my screen goes green and goes haywire. Ugh, i need assistance. I am not good at diagnostics like this.

I notice how you don't even mention the PSU, always an afterthought, till this happens.  Most end users don't know what PSU is and how it might affect their computer. PSU = Power Supply Unit. It comes into play if your PSU cannot suppy enough power to the system. However I don't think in his problem is with the PSU. If the computer doesn't have enough power it will shut down. |
| I'm deviating from the crowd. What is the OS? If Vista or 7, I've had many problems with SLI and Crossfire drivers with Windows 7. 7 kept reverting to a generic driver included in the OS and screwing things up. There were even times it wouldn't boot at all, other times on only one video card. I ended up waiting for a driver update from the manufacturer. |

Did you call Dell tech support yet? http://img.photobucket.com/albums/v364/failedpoet/LJ%20pics/LJ%20Pics%202007/TechSupportKitty.jpg Be glad you don't have an HP,

Quoted: The manual doesn't say which is the proper slot to put it in... hmm It does not matter which slot as long as both are PCI Express of the same type (2.0 in your case). While this might sound dumb. Make sure your monitor is pug into the right card. If your monitor does not show up pug it into the second card. I had this happen all the time when putting things back together. It's annoying. Make sure the card is seated properly. The cards itself needs to be pug into the PSU. Make sure SLI is enable on the mother board. If that didn't work. Go one with one 460gtx. Disable SLI. If that didn't work. Take out the sound card and whatever card is on the mother board. Install one video card If that didn't work. Switch the video card to another slot. If that didn't work. It could be virus or bad driver. If that didn't work. The mother board slots might have gone bad in the installation. Try to reinstall your old video card to see if that is the case. |

Make sure to try it with one card to verify. Bill Gates is all about pissing in everyone's driver koolaid. |

Quoted: Uh dude, a GTX 460 pulls over 300 to 400 wats by itself depending on which brand you have and how much RAM, You are way underpowered and may have killed some other stuff. If his computer was underpowered it would have shut down. I doubt it will kill any hardware other than corrupting the HD which can be an easy fix with chkdsk /f on command. |

You wont kill anything BUT the power supply. I have a feeling its a driver issue. It brings everything out of wack...also.. the PCI could of gone bad.. i really hope not as that is the only slot available... oh and uh.. by some miracle.... my sound card is working now.... wtf. My computer is pms'ing. |

A single GTX460 requires a minimum 450watt PSU each, straight from EVGA's website. Your trying two power a quad core cpu, 2x GTX460's, 4gb DDR2,and a X-fi sound card with a psu that has a MAX output of 700watts and wonder why you may be having graphics issues. Run it with one card and go buy a 1200 watt cooler master psu , then try two cards.
Requirements
Minimum of a 450 Watt power supply. (Minimum recommended power supply with +12 Volt current rating of 24 Amps.) Two available 6-pin PCI-E power dongles ETA: The OCZ 700 psu only runs 18 amp 12v rails.. That card requires a minimum of 24 amps on the 12v rail.. OCZ 700watt psu |

OCZ 700watt psu I just bought a 1000w(10 mins ago from post)... that should be enough... of course I didn't see that factoid of 450 each.. Yikes. I allready sent my order in. This could be an issue of being underpowered. I was testing it out becuase it was running properly.. and it just shut down. That is evident of a power failure. New PSU here we come! Im not disputing the claim but also look at this http://www.guru3d.com/article/geforce-gtx-460-review/13 |

It's crucial that it can supply some steady amps on the +12 rail(s). My Corsair 850W unit does 70A on the +12 rail. |

Talking about electricity is not my strong suit.

Quoted:
If Vipers info is correct (24A for the 460), it looks like you should be okay with that PSU. (30A on two of the rails) +1 Just looked over his pick, That should do fine for running those cards and the rest of the pc in sli.. Output +3.3V@28A, +5V@30A, +12V1@20A, +12V2@20A, +12V3@30A, +12V4@30A, [email protected], [email protected] |

Minimum of a 450 Watt power supply. (Minimum recommended power supply with +12 Volt current rating of 24 Amps.) Two available 6-pin PCI-E power dongles Recommended PSU requirements are calculated for whole system load, not just the video card. Where they suggest minimum of 450Watts with a +12V amp rating of 24 Amps, the Wattage and Amp rating is a combined figure for the entire system, not the amount of Watts and/or Amps the video card itself requires. Quoted:
Uh dude, a GTX 460 pulls over 300 to 400 wats by itself depending on which brand you have and how much RAM, You are way underpowered and may have killed some other stuff. This is entirely NOT true. A GTX 460 card draws a MAXIMUM of 160Watts by itself. 450 Watt PSU minimum is recommended to handle the total SYSTEM power draw under full load. 160 Watts divided by 12 Volts = 13.3 Amps for the GPU. You don't need 24 Amps per 12V rail to power those video cards. |

1000w is a little overkill, 750 is plenty

It only has one rail, so you don't have to worry about this amperage BS. |

Just something to consider, I had 2 7900gtx's sent to me back in the day. 1 of them came bad from the factory ONLY on sli, it worked fine on anything but 1 of the cards when in SLI would bug out. Sent both in and they sent me back 2 brand new ones. worked perfect sense. Sounds like all the same problems I was having with mine, something to consider. |
