No display/No video output

So, I’ve got this old FTX 460 graphics card—definitely seen better days. A few months back, when I actually took the time to test things out, the power supply seemed totally fine, but now? Now we're in trouble. Every time I boot up, the screen gets flooded with these pink pixels right around the Windows 10 logo, and then—poof—the monitor just loses the connection entirely. It’s like the PC and the screen stop speaking the same language. My "fix" used to be just resetting the computer, which worked every single time... until now. Now, nothing. I turn it on, and the monitor doesn't even show a "No Signal" message; it's just dead silence. I even tried swapping out the monitor, but no luck there either. To make matters worse, it randomly shut itself down earlier today, and when I finally managed to get it back up after it had been idling, it flashed some weird resolutions at me before just giving up the ghost again.

Ps. When I try to boot, the PC makes this weird noise—not like a literal pig squeal, obviously, but more like a series of four beeps followed by two quick ones about two seconds later.

It’s likely an issue with your graphics card if you see the same thing on a different monitor. If you can, try borrowing a GPU from a friend to test it out, but before you go through all that trouble, try installing some different drivers first just to be safe.

Alright, here’s the situation... I fired up my rig and got hit with 16 consecutive beeps. My GPU is an ASUS Prime M5A78, and the screen is showing me dual BIOS—which doesn't mean much since I'm definitely not some hardware guru. I went ahead and tested the power supply, and honestly, everything seems fine there.
One guy I talked to tried telling me there's no way to plug a modern graphics card into this motherboard because the connectors are "too new" or something. Is that actually a thing? If I need to dig up more specific specs to figure this out, just let me know and I'll go hunting for them.

Is this regarding the motherboard?

Perhaps this might be of some use to you.

If you're trying to troubleshoot some hardware issues, checking the following AMI BIOS beep code descriptions might help you pin down exactly what's going wrong with your system.

System boots successfully.
Short summary: I'm running into a CMOS setting error.
**Post 1** I am currently troubleshooting a persistent issue with my desktop build. Upon attempting to boot the system, I am receiving one long beep followed by one short beep from the internal speaker. Based on my initial research into common POST codes, this pattern typically points toward a memory or motherboard failure. I have already attempted to reseat the RAM modules, but the error persists. I am considering testing the sticks individually to isolate whether a specific module has failed, or if the issue lies within the motherboard itself. Has anyone encountered this specific beep code recently? Any insights on how to differentiate between a faulty DIMM and a motherboard fault would be greatly appreciated. *** **Post 2** It looks like I’m dealing with a memory or motherboard error. One long beep, one short. Time to start troubleshooting.
One long beep, followed by two short beeps: Is this a monitor issue or a graphics card failure?
I’ve encountered a bit of a hurdle with my current build. I am getting a specific beep code from the motherboard: one long beep followed by three short ones. It seems to be signaling a keyboard error. Has anyone else dealt with this particular sequence before? Any insights would be greatly appreciated.
I’m running into a bit of a headache with my current setup. I'm getting a single long beep followed by nine short beeps during the POST process—specifically a BIOS ROM error. Has anyone dealt with this particular beep code before? I've tried a few basic troubleshooting steps, but I haven't had much luck getting past the error. Any insights would be greatly appreciated.
Continuous long beeps: It looks like the graphics card isn't seated quite right.
Continuous short beeps usually indicate a power-related issue. I would suggest checking your power supply unit first to ensure it's providing stable voltage to the motherboard.

Yeah, it's an ASUS Prime M5A78

In my case, I'm getting 16 beeps, which is just great.
Does anyone here have a solid guide or a decent parts list for putting a PC together?

Whoops, I didn't realize that. Since my GPU and hard drive are shot, I guess I'll just sit here counting beeps.

@To get back on track, I just started a new thread about the graphics card. You mentioned the monitor is fine and the power supply is solid, so I suppose the next step is testing that card in another PC, or trying a different card in yours. I failed to do that last time, and it turns out it wasn't even a power issue—it was probably just a fried PCIe slot.
