I've just built my computer, but I'm having trouble with my GPU not displaying anything on the monitor. There's a red light in the lower left corner indicating a VGA issue. I've already updated the BIOS and chipset but I'm starting to wonder if my GPU, the 9070XT, might be faulty. It's properly seated and lights up when I turn the system on. Any suggestions on what to try next?

I definitely feel you on the seating issue. I had to fiddle with the angle of my GPU before it worked. Make sure it's not only in there but also locked in tight with screws.
First off, have you tried reseating the GPU and the power cable? Sometimes, issues like this can stem from loose connections. Double-check that the other end of the power supply cable is securely plugged in too.
If all connections seem fine, consider connecting to any integrated video ports on your motherboard. Boot into BIOS and switch the settings from integrated to GPU, then restart and see if that helps.
Make sure all power cables are connected properly to your GPU. If it requires two 8-pin connectors and you only plugged in one, that could be the problem. Also, double check that you’re connecting your monitor to the GPU and not to the motherboard.

Yeah, I finally got it working! It turns out it wasn't seated properly after all. Thanks for the tips!
