Hello,
First of all, I've been looking through most of the 'Can't boot with graphics card' topic but none of those describe my problem.
A few days ago I bought a new GPU and plugged it into my PCI 2.0 16x slot. When I tried to start the computer it booted for 1 second (the fans started) and then turned off again. It automaticly tries to boot again but fails over and over again. I plugged my old GPU back in and the computer did start. So I updated the BIOS version, plugged the new GPU in and suddenly it did start.
So the next day when I tried to boot the computer, the same problem occurred. So people suggested to buy a new PSU, which I did
(Seasonic G-550W). I installed it, and it booted just like expected. Played Battlefield 4 on ultra graphics for an hour, nothing weird happened. The next day after work I tried to start the PC again and suddenly the same problem occurred AGAIN.
When I unplug the new GPU and start the system without any graphic cards installed, it does work properly. But when I just plug out the 6 and 8 pin connectors (so the new GPU is still in the PCI slot), it still doesn't work.
What could be the problem? Is my MB faulty? Is there some kind of short circuit going on with the new GPU?
System:
i7 860
MSI R9 280X
MSI P55-GD65
Seasonic G-550W
