I recently purchased the Nvidia GTX560 from Scan, which requires 2x 6 PCI-E cables and roughly a 500W PSU as stated above, however, when I mounted it on the motherboard aswell as put the PCI-E cables in, it booted up fine................................... For about 15 minuites , when suddenly my PC just zapped and turned itself off, the GPU wasn't hot, when I went to reboot it again, the PC wouldn't boot although the mobo still had a green light on it, as I pressed the power button the CPU fan and GPU fan tryed to spin a bit, but didn't and the PC refused to boot.
For some dumb reason I convinced myself it was the PSU, so I bought a new one (The exact same model) and tryed it again....... It didn't boot...... I persume the GPU has a shrt circuit?
The strange thing is that if I remove the PSU PCI-E cables from the GPU and boot it up with the GPU still mounted to the motherbord it boots with no display.. Which is kind of expected..
Does anybody know what's wrong with my card? Remember it's literally under a week old!!
First thing you should have tried is boot up without the GPU in the slot and try with integrated graphics. If the GPU is in the slot it will bypass the integrated graphics and it will automatically be disabled.
If you tried with 2 different PSU I'm pretty sure your GPU is dead, but I would still try the PC with integrated graphics for a while and test everything just to make sure the motherboard is fine and nothing else is damaged.
If the GPU is not under warranty anymore I guess there's not much you can do, but what is the brand and manufacturer of your card? Some of them offer longer warranty than others.
By the way, nVidia does not build the whole unit, they only build the chip. The whole graphics card could be built by Gigabyte, MSI, Asus, EVGA, Zotac, etc... to name a few. That's why I was asking for the brand.
But check with Scan, refurbished products always come with warranty (although shorter) so I don't know how long you had the card.
