I've recently upgraded my PC and it was running fine with my old graphics card (GTX 1050 Ti). After I swapped it out for an RX 580, I started experiencing freezing and crashes, and now my computer just won't boot at all. It powers on, but there's no display, and I hear a soft beep every minute. I've tried reseating the RAM, clearing the CMOS, applying new thermal paste, and reinstalling the cooler, but nothing seems to work. I'm particularly worried because when I tried to remove the CPU, it felt stuck, and now I'm concerned that the thermal paste might have seeped into the socket or around the pins. Any thoughts on whether I should check the CPU socket or if it's more likely a graphics card issue?

It sounds like you might be dealing with a graphics card issue since the problems started after that upgrade. Have you tried booting without the RX 580 to see if the display works with the onboard graphics? Sometimes it’s best to go back to the old card to isolate the issue. It could be a faulty GPU or just something specific with how it's seated in the motherboard.
Also, double-check all power connections to the GPU. Sometimes a loose connection can lead to the GPU not initializing properly.
Just out of curiosity, what thermal paste are you using? Sometimes, if the paste isn't applied correctly, or if you accidentally got it on areas around the socket, it can affect performance. That said, it’s probably more related to the graphics card, especially since you mentioned it all started after that upgrade.
I'm using Artix MC-4. I reapplied it on the CPU because I couldn't boot into Windows, but now it’s not turning on at all. I’m wondering if the GPU is the real culprit here.
Yeah, it could be a combo of both. Just be cautious when working with the CPU; forcefully removing it might just lead to more problems.

That's a good point. I'll give that a try and see if I can get any output. It really seems like the new GPU is causing all these problems.
