PC will not boot at all if a GPU is in the PCIe slot.

SyMix_KD · Jul 30, 2018

Specs:
CPU: Pentium E2180
Motherboard: Abit IP-95 v:1.0 (BIOS V2.59)
GPU: GTX 650 Ti
OS: Win10

Problem:
PC will not boot at all if the GPU is connected in the PCIe slot. When the PC boots, the speaker does a beep, with the GPU connected, it doesn't. The Display doesn't give signal wether it's connected in the motherboard or in the GPU. What's even more interesting, is if I press the power button while the GPU is connected, and then remove the GPU while the PC is on, it will boot normally right after the GPU is removed.

What I've tried:
Changing BIOS so it prioritizes PCIe display adapter.
Clearing/reseting CMOS/BIOS.
Changing CPU (to a Core 2 Duo E4300)
Changing RAM
Changing PSU

The GPU works fine with the same CPU, RAM, and PSU, on a different motherboard.

I'm guessing the PCIe slot on this motherboard is not working, but that's weird because if the PCIe slot wasn't working then the PC should boot normally using the on-board display adapter but it doesn't.

The problem could be running Windows 10 on such an old motherboard and chipset. There probably has not been any support for this motherboard for over a decade.

I find windows 10 to run better on old machines than older versions of windows since it has better memory management and more security features. Still, it shouldn't be the cause of this problem since the OS is only loaded after the initial post, and I can't get to the initial post with the gpu connected.

anyone has a clue what's going on here?

SyMix_KD :

Have you physically cleaned the inside of the PCIe slot?

jay32267 · Aug 8, 2018

It could be that the GPU is pulling down the voltage on the PSU to the point where the machine can't boot from that low of a voltage.

I did, but maybe clearing the dust wasn't enough, you gave me an ideia, tomorrow I'll try using contact cleaner.

But the same PSU and GPU on a different motherboard works fine.

If you can detach the video card while the system is running without damaging the board the board slot is likely DOA. Is the Integrated Graphics Processor enabled ?

karenjoly :

I also think the slot is broken, after cleaning dust and applying contact cleaner it still won't boot with the gpu installed.
This board has no Integrated Graphics Processor, only a basic vga adapter, either way, I did not find a way to disable it in the system's BIOS.
