computer turns on, but monitor says no signal

[random laurel]

i got a used gpu from a reputable reseller, it definitely worked in the store when i was buying it, i tried the old gpu in my pc and it works, i switched the bios video setting to PGE, reset cmos(removed battery held power button for a minute, waited 7 minutes). I also tried reseating the gpu, changing the gpu bios mode, trying a different monitor, different cables (hdmi and dvi), the power connectors are definitely properly connected, please someone help i’ve been troubleshooting for hours now. The gpu is a sapphire nitro+ rx580 8gb

nvm fixed it in a very janky way

How'd you fix it?

[random laurel]

forced a single slot gpu under it into a pcie 4x slot, plugged into that, downloaded the drivers for the rx580, rebooted with the cable in the rx580 and it worked, but bios screen refuses to recognise it

[river cloud]

so you just took the gpu out, and plugged it into the PCIe slot underneath it?

[random laurel]

i didn’t take it out but plugged in a small gpu under it

i wanted to check if the computer actually recognised the rx580

[wicked whale]

Sounds like a motherboard issue if it's not detecting the GPU

Does it detect the spare one?

[random laurel]

windows detects both, motherboard only the spare

probably because it’s and old oem lenovo motherboard

at least it works

[wicked whale]

Does the GPU show up in task manager?

The RX580 specifically

[random laurel]

yup

i pulled out the spare because there’s no use to it now

[wicked whale]

Might just need a bios update to make it appear, but if it's working I wouldn't bother

[random laurel]

lenovo doesn’t release bios updates for my motherboard since 2018 iirc

[wicked whale]

I'd leave it alone if it's working with no issues
