Error encountered during POST expansion after GPU installation.
Error encountered during POST expansion after GPU installation.
Hello. I recently purchased a new Thermaltake Smart 600w PSU to finally support my RX 470 graphics card I bought a few months ago for my Dell Optiplex 3010 motherboard. It comes with 12GB RAM, an i3 3240 processor, and runs Windows 10 64-bit. After installing the new power supply without the GPU, everything functioned properly. The motherboard is quite old and only provides a VGA output, which was acceptable since my monitor supports VGA. Although the GPU lacks a VGA connection, I considered using a TV with HDMI as an alternative. I placed the GPU in the PCIe slot, connected the 8-pin connector, and tried connecting it to a VGA monitor via the motherboard’s VGA output. The PC started up normally, displaying a warning about incorrect video settings. I expected it to switch to the GPU, which it did. However, when I connected the GPU to a TV using HDMI, no signal appeared and the case triggered a Dell POST error code 1 (Blue On/Off button). The manual clarified it was an expansion card issue, not a graphics card fault, suggesting removal or reinstallation of any recently added cards. Removing the GPU resolved the problem; when connected through the motherboard’s VGA port, the PC booted without issues. When plugged into a GPU, it failed to POST. I haven’t tested other monitors like DVI or DisplayPort, nor have I tried another PC for testing. As someone from Venezuela earning around $140 a month, finding affordable components is challenging. One observation was that the PCIe 8-pin connector didn’t fully engage with the GPU board, leaving a small gap. This might be affecting power delivery, preventing the GPU from receiving sufficient voltage. I attempted booting with the GPU installed but without the PCIe 8 pin, which worked fine through the motherboard’s VGA slot. The GPU fans didn’t spin up as they did when the 8-pin was connected.
