I'm in a bit of a bind with my custom-built PC and I could really use some help. When I power it on, the GPU fan spins for a couple of seconds and then stops completely. My monitor just says 'No Signal' and goes into power saving mode. Here's what I've tried so far: I've ensured that all PCIe power cables are plugged in securely, tested different monitor cables, and switched between HDMI and DisplayPort. However, my PC doesn't show the BIOS or POST screen at all. A little background: this build was done by a professional, and the GPU was functioning properly until now. I'm not very confident with hardware, especially when it comes to removing or reseating the GPU latch. I'm trying to figure out if this could be a GPU failure, an issue with the PSU, or something wrong with the motherboard or RAM. Any guidance on what the symptoms might indicate would be greatly appreciated!

It sounds like you might have a power supply issue that's preventing your GPU from getting enough power. This can lead to it shutting down after a brief spin. If you're able to see lights on the CPU and motherboard, it's possible the PSU isn't failing completely but might not be delivering adequate power to the GPU. Have you tried testing with a different PSU to be sure?
From what you've described, it's likely a PSU or motherboard problem, especially if the GPU was working fine before. Also, if you've done any recent upgrades, like a new CPU, check for BIOS updates, as hardware changes can sometimes create compatibility issues. It's odd that this popped up overnight without any changes.
I didn't make any changes at all, which is what’s baffling me. It was perfectly fine yesterday and this happened out of nowhere.
Thanks for the advice! I'm worried about the PSU, but since the RGB lights and fans are working, could that really mean the PSU is still partially functional?
