I recently bought an old motherboard for my collection and during testing it's been refusing to POST when a GPU is installed.The board shown in pic, it has an onboard GT 430.I've tried 3 different cards, a Radeon E9173, Radeon HD 5450 with a PCIe x1 connector and an R7 250X.I tried booting with a different PCIe card, a SATA card with an SSD connected, and it was able to boot from the SSD without issue.Disabling the onboard GT 430 didn't solve the problem, and I also tried disablingI noticed a couple of the CPU socket pins were slightly bent (only noticeable when checking with a light) but it would probably cause issues with the onboard GT 430 if they affected anything related to PCIe.Another thing to note is that the PCIe slot is an x4 slot with an open back and the motherboard's manual states that it can be used for a VGA card (GPU), the BIOS also has an option too use it for this.
>>1576751I just tested it with a SAS card and connected hard drive, it worked without issue.I've also noticed that setting PCI Express Slot to disabled only disables the onboard gt 430.
>>1576751Update, it booted with a FirePro V3900, I still have no idea why other GPU's won't allow it to boot.
>>1576757>have no idea whyPower supply?
>>1576758I tried an R7 260X after the FirePro and it worked, after that I tried the 250X again and it still didn't work, it works with the 5450 now too.
>>1576759I forgot to mention that the power supply is an EVGA SuperNOVA 650 G+ I've had kicking around since I upgraded my main computer, it's too big to fit in any other system I have so I use it for testing.I've tried the 250X and E9173 again, both cards prevented the board from booting so I'll have to test them with another board.
