I've recently decided to try upgrading the computer I've had custom built for me by replacing the motherboard and CPU. This is my first time doing anything like this, so I'm just going to preface by saying I assume it's some obvious (and hopefully simply fixed) mistake I've made out of sheer ignorance.

After reading/watching a few online tutorials, and following the manual step-by-step as best I could, I unhooked everything, removed the old mobo, and put the new one in place with the new CPU. After triple-checking everything I could think of, I tried powering it on. It looked like it was working; all the lights came on, all the case, GPU, and CPU fans started whizzing. But nothing appeared on my monitor. It just said "no signal".

Mobo: Asus M5A99FX Pro R2.0
CPU: AMD FD8350FRHKBOX FX-8350 FX-Series 8-Core Black Edition
16GB (2x8GB) Ripjaws RAM
GPU: EVGA GeForce GTX 770
"Monitor": Sony wide-screen TV, connected via HDMI (has worked just perfectly until now)
toshiba DT01ACA100 1TB HDD

The power supply is an ATX-AP800W.
I get one very short beep, which the manual says means "VGA detected / Quick boot set to disabled / No keyboard detected" (I've got a keyboard plugged in, if that's important).

May I ask what your old system was? Your current components might simply be too heavy for the PSU. USB not detected probably means not enough current is available for the south bridge of the motherboard. Apevia is a brand no one should buy as a power supply. As said in the PSU Tier list, Apevia is a tier Five PSU and;

"Tier Five - Replace immediately. These units are NOT recommended for any system, no matter the purpose. Reference to higher tiered models for a better and potentially money-saving unit."

Replace that thing immediately if you don't want to burn your components. I suspect that's your problem. It's unable to deliver the required load for your new system, and your system fails to boot up because of it. It's a shame that you'll have to spend money on another power supply, but you don't really have a choice. Give us a budget and we'll look for something respectable for your system.

If you're in doubt... What you can try first is putting another old graphics card in that doesn't consume much power, to see if it boots. If it does, it's definitely your power supply. If it doesn't it doesn't exclude your power supply though since the CPU is really power hungry. The motherboard doesn't have onboard graphics sadly to test this. But try taking out as many components as you can to see if your system boots.

I was hoping I wouldn't have to replace anything else, but I guess if it can't be helped, it can't be helped. Thanks for helping.
I'd like to keep from spending anymore than $90 on a PSU, but I understand that might be a little low; if it'd make a significant difference to spend a bit over that, it wouldn't be the worst thing in the world.

After a bit of extra looking around myself, I ended up ordering the PSU you recommended; hopefully it works. It's expected to be here around Friday. After I install it, I'll post back here to confirm that it solved the problem.

Oh, and there's one small question I have.
I've been trying to figure out what was wrong for a few days before I came here, and on one of the sites I was looking at, it said I may want to try resetting the BIOS. I did try that (via the battery removal method), and when I did I was able to get a picture, but it couldn't recognize my hard drive (I could hear the drive making a noise when I started the system, so I know it was connected). I've since flashed back the most recent update for the BIOS from the Asus website via the "USB BIOS Flashback" feature the motherboard has, but I was wondering why I could get picture then, and not now. (This seems like something I should've mentioned before, but I can get a little scatterbrained sometimes and had forgotten about it.. My bad)

The new PSU arrived today, and I went and installed it first thing when I got home. I made sure everything was hooked up, tried it, everything turned on; but I still get no picture...

Do you have any other suggestions?

I also just noticed that my TV dims when it's been left on and nothing's happened, but when I turn my computer off/on, it brightens again, so I think it's getting some sort of signal from the GPU, at least.

Hm... Interesting. Let's see... Some basic stuff to check first.
- Is the source on your TV set correctly, and not on a different HDMI port? Probably, but just double checking.

- Are you sure your cable did not get damaged during connecting and disconnecting? Try another one just to be sure.

- Try resetting the BIOS again.

The more advanced stuff, what I would do for now is;
- If you have another graphics card, no matter how old, put it in to see if you get a picture. If not, try the next thing..

- Disconnect everything except the (current) graphics card, CPU, and one memory stick. Boot up and see if you get a picture. If not, use the other RAM stick instead. In case you do get a picture, add things one by one to see what is causing the problem. If you don't, it might be a faulty motherboard or CPU.


I have that same motherboard and everything booted easily out of the box. What happens if you just leave it on for 15 minutes when you're not getting a picture? Does it stay on normally?

I went ahead and tried each of those in order as best I could:

I'm 90% sure it's not the HDMI cable, as in the time I spent waiting for the new PSU to arrive I was using it with one of my consoles and it worked just fine. Nevertheless I switched it out, and nothing happened.

I tried resetting the BIOS again by removing the battery for 10 minutes like I did last time, but for some reason this time I can't get a picture with the BIOS menu, like I did when I had the old PSU installed.

I don't have any other graphics card, because this is really my only computer, and I haven't had a reason to upgrade or replace that part since I got it, so I had to skip that step. Though, the card seemed to work just fine with my old motherboard, so unless I somehow managed to damage it when installing the new one (which isn't impossible), I don't think it'd be that.

I tried unhooking everything I could: the HDD, the Netis LAN card, both optical drives, one of the two sticks of RAM, even the CPU heat sink fan, but nothing. Even tried switching the RAM sticks, and changing which of the 4 slots they were in. No good there.

I tried leaving it on for 15 minutes, but nothing happened. The screen stayed blank, the computer stayed on; nothing very eventful. I tried using each of the 3 HDMI ports on the TV, but they all had the same result: when switching the input method on the TV to an unused slot, it immediately read "No signal.", but when I set it to the one I had the computer plugged into, there was a noticeable pause of about 5 seconds before the "No signal" notification came up; like it was trying to connect but couldn't.

Unless there's anything else you can think of, I can only imagine something's physically malfunctioning. That, or maybe there's some default setting with the motherboard that makes it want to use one of the the DVI ports on the graphics card instead of the HDMI, but I can't think of how to change that without being able to access some sort of menu, and the TV only has an old VGA port, anyway.

The graphics card is supposed to detect the HDMI output automatically, rather than any other output that's not being used.

Let's see... It's a hassle, but you can put back the graphics card on the old motherboard and CPU, to rule out that the graphics card was damaged during the switch. You don't have to take everything out of the case. You can hook up your old power supply, put the old motherboard on the anti-static sleeve that came with the new motherboard, make sure nothing conductive comes in contact with it and don't touch it while it's on, and connect only the necessary things with your old power supply. So in short, old motherboard + old CPU + graphics card + old power supply + RAM stick.

If everything works fine still and you get a picture, we'll have to determine if it's the CPU or the motherboard that's faulty. My guess is the CPU, but it's an educated guess and not guaranteed. Which old motherboard and CPU do you have? If it's an AM3 cpu, it should work in the new motherboard as well. This way, we can rule out either the new motherboard or the new CPU. It's a huge hassle as well to do this, since you'll have to clean and re-apply thermal paste if you remove the cooler.

Before reading your reply I went through all the rigamaroo to completely reinstall the old motherboard, and I got a picture, so it's not the GPU. However, I can't switch the processor, because the old motherboard/processor has an FM2 socket :/ so I can't be completely certain which one; though I would agree with it being a faulty processor, as I'm not very smart and didn't know about the different sockets until after I ordered the new CPU, so I tried putting it into the old motherboard... I didn't apply any pressure to it, but it did sit on its pins with its own weight, so it may have been damaged then.

It was shipped from and sold by Amazon, and their return/replacement policy is fairly 'no questions asked'. I'll send mine in, and the replacement should be here between the 15th and 18th. I'll try things out then, and hope for the best.

Well, I received and installed the replacement processor today, plugged everything in, and fired it up. Same result. I guess that means something's wrong with the motherboard, so I suppose I'll see about getting that replaced.

Before returning the motherboard, do you have a VGA cable you can try? I'll guess your new mobo has UEFI (with a default resolution of 1280x1024) while your old one has BIOS (probably at 800x600) and your TV doesn't support 1280x1024 over HDMI (as many seem not to). It might over VGA. If not, and you have access to another monitor, I'd try that before exchanging anything.
