[SOLVED] PC won't boot and no peripherals are getting any power ?

[Isaacn90]

Hi everyone,

Today I attempted to install a 2nd GPU into my case (2080) so that I could mine on one card and game on the other.

I connected both GPUs up and attempted to boot the device with no success.

My PC is posting either the 04 error code or 55 error code and sometimes 60.

I've tried literally everything, removed all hardware individually to see if it would boot, changed ram slots , re seated CPU , checked case to ensure the mounting screws are all correct, removed cmos battery, reset using CMOS reset button but still nothing. The old girl won't even boot with no GPUs in and there is never any power to the peripherals. Please help , I'm in lockdown so can't take it to any shops either

I7- 6700k
Asus maximus viii extreme
Nvidia RTX2070S
Rtx 2080
Neptune 120XL AIO
Evga 850 g2 gold plus
Crucial 1tb m.2 P2
Crucial 125gb Ssd SATA
2x 8gb g.skill ripsaw DDR4 2400

How old is that Evga 850 g2 gold plus PSU? Heavy use to date for gaming, video editing, and earlier bit-mining?

Did you mix and match modular power cables when you installed the second GPU?

When you "connected up" the GPU's exactly how did you do that?

If you have a multi-meter and know how to use it (or know someone who does) then you can do some testing on the PSU.

Not underload so not a full test. However, any voltages out of tolerance would make the PSU very suspect.

I think the power supply is probably about 5 years old (I'm not the original owner so not sure really)

I've gamed pretty heavily on it for the year plus it's been mining for maybe the past 3 months

Not quite sure what you mean by mix match ? Do you mean vga 1 and 2 on one GPU and 3 and 4 on the other

I'm not exactly sure how I had it connected because I've unplugged everything now but I had a 4 pin and 6 pin connected to each GPU (no clue what slots they took up in the power supply though)

Sadly I don't have a multi meter . Is there any other way I could test the PSU ?

Thanks for all your help mate

Mix & match (in any number of situations) gives a person the ability to make whatever choices or combination of choices that they wish to make.

In the "IT context" it means that you simply use plugs and ports that physically fit together. However, the problem is that a physical connection fit is not necessarily an electrical fit. There are standards but those standards are not always adhered to.

So changing cables (plugs and/or ports) around could result in the wrong voltage by value or polarity going where it should not go. Often ends badly....

Especially if a manufacturer decides to not follow the standard configurations and uses a proprietary (they make up their own standard) configuration. Common tactic to lock customers/end users into a particular product line or service. If they use, for example, a non-standard configuration then you may be forced to purchase their cables....

If you are unable to test the PSU then that very much leaves you with simply swapping in another PSU.

So you must ensure that the new PSU plugs/connectors do indeed match the original PSU plugs/connectors.

Keyword being "mapping": knowing pin by pin the voltage, polarity, or ground reference for each pin in a plug (male) or port (female).

Fortunately that information is generally discoverable via motherboard User Guides/Manuals, PSU User Guides/Manuals, and likewise for other installed components.

Just takes time to work through the documentation.

Start with the motherboard's User Guide/Manual. Take close and careful look at the connector's pinouts. What you plug (GPUs) into those places must exactly match.

Pin for pin.

Takes time and effort.

Okay right got ya. I can confirm that I had plugged the correct cables into the correct devices . CPU labelled cables for the 8 pin CPU connector , mb connector for mb and VGA cables for the GPUS

Okay so I managed to get myself a volt meter and started off with testing the mb connector and the CPU connector. The voltage of all pins is correct . Can I rule out the PSU as the issue then and move onto the the motherboard?

Thanks your being a big help

 

[Ralston18]

The PSU cannot be completely ruled out. The voltage tests are "not under load".

And there could also be some intermittent problem with a connector or cable; in other words, the problem may come and go.

Try to borrow a PSU from another known working system. Just another way to check things.

No harm in proceeding with other tests just as a matter of elimination.

Be methodical and take your time.

Hey team,

Quick update, I have now tested the system with a known working PSU and had the same results

Error code 55 when two sticks of ram are interested and error code 04 when there is one.

What would be the next component to test ? I'm assuming buying a new stick of ram and seeing if she will boot. I am leaning towards either the motherboard or CPU being toast though

**Update I've just tried with a new stick of ram with no improvements. Is there anyway I can test CPU or motherboard without getting new ones ?

Thanks again for you help

Remove the GPUs, disconnect all the storage, reset motherboard settings to default and connect the monitor to the motherboard. You can enter BIOS after that?

Hey mate ,

Tried that still get the same error codes and no output
