Computer Not Booting, Yellow Light On Motherboard

[Honey]

Long story short, I bought a new GPU took PC to pieces and it won't fit on my micro ATX board. Then I rebuilt my PC and it won't boot and is showing a yellow light on the motherboard. The fans on the GPU and in the case are spinning at full power, faster and louder than I have ever seen them before, but my TV says "no signal through PC". Any suggestions. Thanks.

The OS is on one and I have another, and I understand why it is a problem I'm just saying how much of a problem is it as it doesn't seem logical and I have never heard of it before

Not really sure you never hearing of it before being relevant here, with all due respect.

Boot your computer into the BIOS. See what SATA port is set for your computer to boot the OS from. Make SURE that drive is plugged into that exact SATA port.

OR, you can change the BIOS setting to boot from the port you have the OS drive plugged into now.

Either way should be fine.

EDIT..What I said here may seem a bit rude, but you seem to have ignored my suggestion and question on this point from when I first posted it for the simple fact that you don't think it was logical, according to what you said. Sorry about that then, if it was a bit rude.

EDIT 2.... If you cannot get video signal still, you may need to temporarily use the on board video port for the motherboard so you can get into the BIOS and see what is going on there.

Go on Dell.com/Support and enter your service code #
It's located on the Dell sticker on your PC-Case along with that model#
The service code input on their site will better define which exact "Optiplex 760" you have and from that site is Support/Downloads, look at the FAQ/Help section or Download the PDF-Manual for that system from there as well.

I have this same computer, the Optiplex 760, if it is the same model as yours of course. It is a BTX case, not ATX, so everything is backwards (upside down) to what the configuration of an ATX case is. I actually like the idea of a BTX case, but the issue is there is not much room in there for a dedicated GPU, as you seem to understand. The SATA port(s) may be blocked partially or all the way, too, so keep that in mind.

Yes BTX overall was a fail in the market. If you still have one, I would just keep using it as-is, or get rid of it.

Right. Agreed. This Dell was the first time I had encountered a BTX case, as immediately found the issues with a dedicated GPU in it. No room hardly at all. So that also means if you can get one in there, that will decrease air flow even more.

did you plug the video cable to your gpu (ATI Radeon HD 2600 Pro 256mb) and not thru the motherboard?
what video cable did you use (dvi, hdmi, vga)?
have you tried using other video cable or use another video port?

I used a DVI to VGA adaptor and then VGA to plug into the screen

But it will have to wait until I'm back home later 😭

cpu from 2008, video from 2007, old 300W BTX PSU, unknown mobo from 2008... with dried electrolytic capacitors and nearly dead lithium battery... eah it's really software problem
strange ram configuration - looks like someone use 3-5 different modules, installed in DDR2&DDR3 slots at same time

or just trolll us ;)

Hey don't dis kid it's a good computer

I'd start with the basics:

1. Remove the Graphics Card
2. Remove all but 2GB of your memory(preferably keep 2 of the same brand plugged in)
3. Remove your hard drive which is used for data(leave only the OS drive installed)
4. Check you have plugged in the power to the main board correctly (i.e. The big plug & often the smaller 4 pin plug near the processor as well)
5. Plug in a monitor to the mainboard and boot up. (if you get text/some kind of signal, congratulations you could be ok).
6. If you did get signal did it managed to boot into windows?
7. If your computer did not boot into windows, but it did give a signal, change the sata port and boot again (repeat

I fixed it, everything is Gucci. Well kinda. The drives are running extremely slow and the yellow light is still there also the internet never cuts out but when u can see the bars of disk and network when downloading on steam, they are all over the place and are really low But it's on 😂

[Honey]

And also I did get the blue screen of death 😂

[Honey]

The problem was as simple as I'd missed a power connector for my motherboard. But I don't know about the other stuff

[Honey]

Like the yellow light, I don't know why that's still there
