Asus GTX 660 Problem - No display

by alexinlondon / April 28, 2013 2:41 AM PDT

Just came home and booted up my desktop. I heard it power up and windows start, but no display on the monitor.

It was connected with the HDMI, so I tried switching to the DVI cable. Still no display.

To rule out the monitor I brought over my TV and tried that (via HDMI and DVI) - still no display.

So I opened up the PC and checked power was getting to the GPU - the power light on the GPU is on and the fans are spinning.

I took the GPU out and tried re-starting the computer with the HDMI connected to the motherboard on-board graphics. The PC started up and the display works fine.

So it seems it's either the GPU or the PCI slot or the power to the GPU??

Can anyone give me some troubleshooting advice please. All components are only a few months old.

I tend to blame the video card if it doesn't display, why figure out why it doesn't work. If you hadn't blow-off the card and re-try again and fully seat it and check results. If the display still doesn't show then consider the card a goner. Video cards do a lot of GPU work and if intensely used, it will finally get hosed. Review any talk about the 660 and find out what other users have experienced or its history. It may have warranty, use it. Also, you can test on another PC?


It is already "overclocked" so its being pushed by the maker, worth noting.

Thanks Willy,

I've already sent an e-mail to Asus to initiate the warranty replacement procedure.

The only other thing I did was remove all NVIDIA software / drivers / registry settings while running on iGPU, then tried booting up again on the GTX 660, but same result, so I think as you said something has happened to the GPU itself.. disappointing with a card that was new only a few months ago!
