Purchased. Check out this graphics card listing on Links: http://www.links.com/graphics-card-listing-example
Now I can't even boot into macOS. I power on the computer and nothing happens. There isn't even the standard POST beep code when it starts up. I guess I'm stuck. What now?🙂🤷
So, where exactly did you go to pick up that card? Did you actually walk into the store, or was this an online order? There is always the possibility that you were dealt a dud right out of the box; I have heard people complain about their service before. As far as I can tell, this card doesn't require any supplemental power—I don't see a dedicated connector on it. I believe they are categorized as low-end, though I suppose that changes if you're trying to push Full HD at max settings. Either way, there is no need for extra power cables here. You really only need a 400 or 450W power supply for a setup like this. Actually, I suspect your PC might be staging a protest. It probably worked so well with the old card that now it’s just acting out. Just kidding, I guess.
I had a similar experience with my RAM. Even though I'd applied contact cleaner, things just wouldn't cooperate. It’s possible the PCIe slot where you seat the graphics card might be oxidizing. However, if you aren't hearing a beep code during startup, I guess it might be an issue with the motherboard or perhaps the power supply.
My friends have run into similar issues. One of them swapped out a component but didn't properly engage the power supply switch—he just unplugged it, which ended up frying his motherboard. Another one tried to pull out his graphics card and damaged the board in the process. There are plenty of ways this can go wrong. I’d suggest taking your setup to a shop or trying it in a different PC entirely. You might also want to check if a cable is causing some kind of short or if the PSU connection is loose. Try unplugging everything and reseating it all, though I wouldn't touch the CPU; leave that alone. You didn't mention if you hear any activity at all—like the CPU fan spinning or anything else. I actually have a power supply with a built-in surge protector. If you press the power button too quickly, it seems to trip a safety mechanism inside the unit. It makes a clicking sound, and then you have to toggle the main PSU switch off and on again. Sometimes I have to hold the power button for about a second or two before it finally boots. At first, I assumed the unit was defective, but the repair tech suggested I might just be hitting the button too fast. When I don't rush it, it works fine. If I just press it and hold it briefly, it goes up without an issue.
