"My card shut off yesterday"

Cards don't shut off.

"screen would show the gateway logo..."

That means there is nothing wrong with the video card or the monitor.

"...and windows loading but then go black"

That means it's a Windows problem, not a hardware problem.

"i went into bios and set it to onboard vga"

Did you connect the monitor cable to the onboard video port?

Which specific Gateway model is it ?

That's probably on a label on the outside of the case.

You could try the monitor with another working computer, but there's probably nothing wrong with it.

In most cases there is no setting in the bios that actually disables the onboard video - the onboard video is disabled automatically when there is a video card installed in an AGP or PCI-E X16 slot.
(The only exception to that, that I know of, is when the mboard has onboard video and the main chipset is a recent one that supports Hybrid video - both the onboard video and the video on a card in a PCI-E X16 slot working at the same time.)
It's NOT disabled automatically in any case when there's video card in a PCI slot.

"It did say "Your video card has stopped working" when i had it set to my 460"

Some times a video chipset is damaged such that it works in basic VGA mode, which is what it's using while booting before Windows loads, or in Safe mode, or in Enable VGA mode, but it doesn't work in Windows when you load Windows normally and the specific drivers have been loaded in Windows for the video adapter, or visa versa.

Remove the AC power to the computer.
Unplug the 460 video card.
Plug the monitor into the onboard video port.
Restore AC power and try booting the computer.
If nothing else is wrong, you should have video while booting before Windows starts to load, and after it starts to load in Windows.

If you DO have video every time before Windows starts to load, but no video in Windows. with the onboard video...

For 2000 or XP...
See response 9 here:

starting at....
Boot into Enable VGA mode.

Note - that's missing this...

Remove any bootable CDs or DVDs you have in drives.
Press F8 repeatedly while booting, don't hold down the key, starting very early in the boot.
When the Windows "Advanced..." menu appears, choose Enable VGA mode.

For Vista, or Windows 7....

There is probably no setting you can change in the mboards bios that actually affects whether you get video from the GTX 460 card while booting the computer, but I can't confirm that untill you have told me / us what your specific Gateway model is.

It's extremely likely that the GTX 460 card is damaged, or your power supply is malfunctioning, or you may have damaged the PCI-E X16 slot circuits when you were fiddling with plugging in or uplugging the card, if you didn't have the AC power to the case / power supply REMOVED AT ALL TIMES while you were doing that.

If the GTX card IS damaged, it won't work in ANY computer.

The onboard video is probably duisabled automatically when a working video card is installed in the PCI-E X16 slot, but it may or may not be disabled auitomatically when the card in the PCI-E X16 slot is not working properly, or when the PCI-E X16 slot's circuits are damaged.

GeForce GTX 460 - Specfications
http://www.geforce.com/hardware/des...

Minimum System Power Requirement (W) 450 W
6-pin & 6-pinSupplementary Power Connectors

PNY
GTX 460 OC 1024MB PCIe
http://www3.pny.com/GTX-460-OVERCLO...

Minimum System Requirements

•PCI Express or PCI Express 2.0-compliant motherboard with one dual-width x16 graphics slot
•Two 6-pin PCI Express supplementary power connectors
•Minimum 450W or greater system power supply (with a minimum 12V current rating of 38A)****

What is the max (output) wattage capacity of the power supply ?
That's probably on an obvious label on the side of the PS inside the case.

If it's a lot less than 450 watts, or if the max total current at +12V is a lot less than 38 A (it may have more than one +12v section) , the GTX card may work fine at first, but the PS will probably be DAMAGED eventually from it being overloaded when the GTX 460 card is installed

Did you install the 600 watt PS yourself ?
What make and model is it ?

it's an OCZ 600W model OCZ600MXSP, No the same person who installed my card a year ago installed my ps at the same time.

"OCZ 600W model OCZ600MXSP"

Apparently it's a decent high efficiency model with a 3 year warranty, not an el-cheapo model.
However, any power supply can malfunction.

If the power supply was bad would the fan of the card come on?

You said "its working fine with the onboard card"

It's a video adapter, but it isn't a video CARD unless it installs in a mboard slot and can be removed

If the computer works fine with the onboard video, there's probably nothing wrong with thje PS.

It's unlikely that your decent mofdel of PS has gone bad unless it's been damaged by an externasl event.

The fan on the GTX 460 may or may not spin on the video card when the card, or when the circuits of the slot it's been plugged into, has / have been damaged.

Trying the GTX 460 card in another working computer that has a PS with enough capacity, if you can, will confirm whether the card is damaged or not.
