GeForce 460GTX Troubleshooting.

Postby Judge Rabbi » Tue Jan 15, 2013 11:36 pm

Query concerns a GeForce 460GTX 1GB graphics card (GigaByte model).

PC running a Intel I5 installed onto a LGA1156 socket mainboard failed. I assumed the card is fine since the fans spun on the heatsink.
Salvaged card and installed onto a new LGA1155 mainboard. Fans do not spin on PC boot and the monitor remains blank - it does not report a lack of signal from the card.

On-board video tested, PC works fine with Win 7. I've not re-installed Win 7 - running off the install when connected to the LGA1156 mainboard.
Used a program to see connected hardware (called SIC, SXI or something like that) and it showed that the 460GTX was plugged in. Nvidia drivers refuse to install - even after uninstall and registry clean.
(Gut feeling that it may just need a clean install to 'spot' the card - would like someone to confirm before committing to a Win7 install!)

Some users reported heatsink fan failure. Any ideas?

Did you plug the PSU into the graphics card?

Test the graphics card in another pc just to make sure it's not fucked? If it works fine then yea format time, it's quicker and less headache inducing trying to sort out different conflicts between the motherboards left in the registry.

Yuss the two six pin PSU connectors are plugged into the card.

While troubleshooting the old mainboard (LGA1156) with the card installed I saw the fans work fine then. Gonna have to try it in another rig - gawd I hate PSU cables.

Right, determined that the 460 GTX is kaput.

Installed a R7870 Core edition card into the rig. Fan spins up on graphics card heatsink but no display on the monitor (monitor acknowledged signal but stays blank).

Tested rig with a working HD 5700 card and that displays a image. Works fine (but then again it is much smaller and less power hungry.)

I'm now looking at the PSU, which is 600w and two years old. I'm assuming the PSU is on its way out and is not providing enough power to the GPU - thus the card is staying put in safe mode and won't be recognised in Device Manager.
But I usually see symptoms of dying PSUs first, such as the PC turning on and off when the powered up and sudden PC shutdown during heavy use load.

Thoughts? I got unlucky and got a dodgy GFX card? PSU fine but best to replace?

Yeah, I wouldn't have thought it wasn't a PSU issue, as you said they tend to cause reboots when failing. Looks more like a card issue. Small chance its a mobo issue, check for blown capacitors on it. Any slight bulging or leaking means the capacitor is fuckered.

Edit* I missed an important word.

I would have thought a 600w psu would still be fine as long as it is a decent make. Sounds like the card might just be a bit iffy. Have you tried unplugging any unnecessary components like a sound card or extra hardrive, maybe a fan or two and seeing if the reduction in power usage helps?

I gambled wrong!
The ATi card works fine, meaning its a PSU fault - meaning that the 460GTX might be fine...

Well thats a first for the PSU...

Wait what? Testing with another card works fine so therefore the card that didn't work must be fine?
IMO :P :wink: :P :wink: :P :wink:

The card tested (and that worked fine) was a ATi 5700 series card.
Power requirements for the 5700 card is low compared to the ATi 7870 - which I thought was DoA but it turns out that it works fine after all!
But if its a lack of power to the card then maybe the GTX460 was fine all along and it simply was not working due to bad PSU? (I know the fans don't spin on the 460 on POST but i've got a bit of doubt about the card current state now and I need to test it again with a new PSU.)

Woopdeedoo this is fun.

If your thinking it's the PSU and not having enough power on the 12v rails then I'd suggest going for a beefy PSU like one of these http://www.scan.co.uk/products/800w-cor ... -fan-atx-v or a modular variant if you want to cut down on cable mess/routing.

A quick note -

The GigaByte GA-Z77M-D3H mainboard does not like working with a ATi R7870 graphics card.
