My problem is similar to the previous two posters: my computer does not boot at all (no POST beep, no signal to monitor) when my graphics card is inserted, but it does boot without it using the integrated graphics.
Here are the things I have checked:
- The video card works, tried it in two of my friends' computers.
- The PCI-Express slot of my motherboard works, tried plugging in two different graphics cards into my motherboard and they both worked. And of course the integrated graphics also works.
- It is not my PSU that is faulty. Got an alternative PSU from a friend, tried powering my computer from that one, the symptoms are exactly the same: boots without the video card, doesn't boot with it.
- Did the above with all my SATA devices completely disconnected (both from the PSU and the SATA cable), boots without video card (at least there is something on the screen: it says that no boot device was found), doesn't boot with it. So it cannot be a software problem.
- Successfully booted my computer with both of my memory modules separately, of course without the video card.
- Tried resetting the CMOS, didn't work either.
- Motherboard: MSI 785GM-E51
- CPU: AMD Athlon II X2 250
- BIOS version: 2.2
- Integrated graphics: ATI Radeon HD 4200
- Video card: Gigabyte GV-N960IXOC-2GD (GTX 960)
- Power supply: Enermax MaxPro 400W
- RAM: Kingston HyperX 8GB DDR3
It is important to note that my video card is still under its warranty period; haven't tried giving it back to the retailer yet because the issue is only present with my own computer. I'll try giving it back as a last resort when I give up trying to find the exact fault.
I only have one theory at the moment: the video card has a PCIe 3.0 interface while my motherboard only has PCIe 1.0. Is it possible that the video card stopped working with the old PCIe slot for some reason? Both my friends' computers in which I tried my GPU had newer motherboards (PCIe 2.0 and 3.0 respecively), and both video cards I received from my friend have PCIe 2.0. So currently I suspect that either my motherboard cannot work with a 3.0 GPU or my GPU doesn't work with my 1.0 motherboard. Is this even plausible?
Hopefully I will be able to try another friend's GTX 960 in my computer next week or so.
This issue has been going on for about a month, I'm planning on buying a new motherboard and CPU anyway, I'd just like to sort this out. My GPU is still under warranty after all, I don't want to waste an opportunity if it is indeed faulty.
Any ideas welcome, thanks in advance
