So I deliberated building this computer on this thread:
https://www.bleepingcomputer.com/forums/t/701462/upgrade-vs-build-new-vs-buy-new/page-3#entry4836903


I ordered:
Ryzen 5 3600
B450 tomahawk
Rex 580


I very carefully assembled the system. When I go to turn it on the cpu cooler can turns on and one of the case fans turns on. The motherboard has a blue back lighting and the red cpu led light is on.

Nothing shows on the displays.

The GPU fans do not turn on.

Ive checked all the connections. Removed all the drives, etc.


Yall have any ideas? Im about to order another motherboard and CPu out of desperation.

Thanks,
JK

Manual for the B450 says

Supports 1st, 2nd and 3rd Gen AMD RyzenTM, RyzenTM with RadeonTM Vega Graphics, 2nd Gen AMD RyzenTM with RadeonTM Graphics and AthlonTM with RadeonTM Vega Graphics Desktop Processors for Socket AM4


Forgive my ignorance, is the Ryzen 5 3600 a 5th gen?

Can I flash the bios with all the components installed? Would rather not risk damaging the CPU trying to get it out.

It should be fine, but yeah should have updated the BIOS first but oh well.

It should be fine once the BIOS is flashed, you got everything installed so no use getting everything removed, it will be fine

Good deal! I took my cooler off yesterday... just to look around. Pain in the ass to get back on to the bracket while in the case! Happy I don't need to do that again.

Do you have a computer that was previously working and then suddenly it doesn’t? Or did you just built a new computer but it won’t start for some reason? A red light on the motherboard means that there is hardware in your computer that is not connected properly or is not working as expected. Depending on the manufacturer of your motherboard, there may be multiple red LEDs on the board for specific computer parts for easier troubleshooting.

Older motherboard models usually have one red LED. When it is lit, you have to run through all the parts of your computer to find out what’s wrong. Newer ones usually have a specific LED for parts that are most likely to fail. Most common LED indicator are for CPU, RAM, VGA/GPU, and BOOT.

CPU – a lit red LED for CPU normally means that the CPU is not detected by the system. However, this does not necessarily mean that you did not place the CPU properly on the socket. It could be that the CPU fan is not plugged properly or not plugged at all. Another possibility is that your CMOS battery is empty and needs changing.

RAM – a lit red LED for RAM or DRAM simply means that the computer RAM is not detected. To fix this, check on your RAM and make sure that all you RAM are inserted to the slots properly. Newbie mistake that you can make when inserting RAM is not to push it until both clamps on the ends of the clamp locks the RAM in place and make a clicking noise.

VGA/GPU – a lit red LED for VGA or GPU means that your dedicated Graphics Card is not detected. Check on your card if you have plugged the correct power connectors and that your card is fully inserted to the PCIe slot.

BOOT – a lit red LED for BOOT means that all boot devices cannot be read or detected. Boot device is where your operating system is stored. To fix this, check on your storage devices to see if there are any loose connectors.

You already checked all the parts and the computer is still not fixed. What’s next?

Reset the BIOS of your motherboard. To do this, check on the manual of your board or see the website of your manufacturer. There are usually a jumper in the board that you can short to do this. You also have the option to remove the CMOS batter for 5 minutes or more.

Replace your CMOS battery. If you tried resetting the BIOS and your computer still won’t start, this is the next step to do. An empty CMOS battery will trigger a red CPU debug LED. (based on our actual experience) CMOS batteries are relatively cheap. If you don’t have any or just want a spare, you can buy one from Amazon right here: https://amzn.to/2L4EIT1

CMOS Battery

Unplug everything. If you have tried BIOS reset or changing CMOS battery and you still have no luck fixing the computer. Try this. Unplug your computer then remove all the parts connected to the motherboard. Remove all the connector pins connected to all the parts inside the system unit. Unplug all connectors.

While unplugged, check the Connector Pins of your RAM , GPU and storage device. Dirt and whatever can build-up on the pins and may result to non-contact to connector pins on the board. You can use a pencil eraser to thoroughly clean the PC connector pins on your RAM, GPU and storage device.

Check all the pins of the power connectors. Make sure nothing would the connector pins from contacting the pins on your board and other parts of your system unit. After this, plug everything back and try again.

If none of this fixed your computer, it is highly likely that a part of your computer is broken and needs replacement. How to check which part of the computer is broken?

Boot without GPU. Try booting without your GPU. If this does not fix the issue, move on with the next part. However, your GPU is busted or something is very wrong with it if this fixed your issue. To check the health of your GPU, try plugging it into another computer to see if it works.

If it doesn’t work, then it’s a dead GPU. If your CPU does not have integrated graphics and requires a discrete GPU to display anything, you’re out of luck. I’m sorry but you will need to buy a new one. We can’t recommend anything right now because It’s very hard to get a hold of any GPU right now and everything is overpriced so good luck mate!

Boot with one RAM. If you have multiple RAM, try booting with just one. Switch your RAM if the issue is not fixed. Make sure to test all of them on each RAM slot. Again, one of your RAM is busted if this fixed the issue.

Looking for a new RAM? Check out Corsairs mid-tier offering from Amazon here: https://amzn.to/2JYlaiQ

Remove all External Peripherals and Connectors. Remove your mouse, keyboard, external drives, and even ethernet cable. Of course, leave the power cable and the connection to the monitor. If this fixes the issue, try plugging in the peripherals one by one switching each time you boot your computer to see which one is broken.

If none of the steps above fixed the issue, here’s next. By this time you have checked on all parts of the computer except for two; the motherboard and the power supply.

First, check your power supply. If you have a modular design, try switching cables especially the ATX power connectors. These cables may vary in the number of pins but they usually have a design that are unique compared to other power connector cables so it’s easy to distinguish them. They usually have 20/24 pins and 4/6/8 pins and plugs in directly to the motherboard.

If changing cables didn’t work, try using another power supply that you are sure is working. If it works, then your other Power Supply is obviously broken and needs replacement. If you’re looking for a replacement, it’s best to select higher capacity Power Supplies mated with high efficiency to protect your computer parts from unstable electricity and the likes. We recommend Seasonic’s offering that you can check from Amazon: https://amzn.to/2In2SXX

We have been using Seasonic PSU for the past 5 years and we have never encountered any issues on our PSU. Note that this is only based on our experience and may not necessarily apply to you so please do your own research when buying stuff online.

If the computer still won’t start, then you found your culprit. It’s your motherboard. If it’s still under warranty, have it replaced or fixed. If it’s old, you need to buy a new one. If you have an old and slow system, consider buying a newer system with a new motherboard in it. If you still want to reuse your existing parts, make sure that you will buy a motherboard that is compatible with your existing CPU and other peripherals.

MSI Tomahawk B450 Max BOOT issue

niko91.lt15a502e0 said:

Hm, interesting. I'm now trying with HDMI cable,so it's not workoing. I've installed another BIOS version from 2019 (7C02v32) and now I pass the CPU check, DRAM check but struggling on the VGA red indicator and now I hear 3 BEEP sounds from the motherboard. It's interesting because once I pass the VGA check and the CPU check but I was stucked on the BOOT red light, now I can't pass the VGA and hearing this beep sound. Even if I had this issue with the Nvidia bug for DP, I don't know how to fix it because I can't even go throught the BIOS, don't have any integrated graphics on the processor and etc. Any other suggestions?

Click to expand...

Have you tried clearing Cmos again (via the jbat method) since seeing the vga light?
Have you tried plugging the graphics card into another pcie slot?
What happens if you boot without the displayport/hdmi cable plugged in the graphics card? Any red lights?

Edit- Oh and I've seen the vga red light appear before (with no display) when my displayport cable wasn't fully pushed into the back of the graphics card, once I pushed it in snugly the pc booted fine (im using a Msi B450 Mortar max).

Edit 2- Another thing worth trying, disconnect the reset wire connecting the case to the motherboard, and try temporarily disconnecting all sata cables plugged into the motherboard. I have seen a red cpu light appear a few times when plugging in a sata ssd drive, mysteriously a reboot fixed it.

Edit 3 - If the above doesn't help, maybe rebuild the computer outside of the pc case to rule the case out (place the motherboard on the motherboard box).

What the Red Light on a Motherboard Means (and How to Fix It)

A red light on your motherboard means internal hardware is either plugged-in incorrectly or not working.

  • Internal hardware examples include the CPU, RAM or a graphics card.
  • Sometimes a dead CMOS battery may be the culprit.
  • Boot errors on the hard drive where the primary OS is installed may also cause the red light.

The red light always appears after the computer has been turned on, but generally it will not boot, enter the bios, or display content on the monitor.

The specific error depends on the motherboard and where the red light is located. Some motherboard manufacturers include labels on the board to explain what’s wrong. Older motherboards may have a single, unlabeled red LED, which makes it more difficult to discern what’s going on.

If you cannot tell what’s wrong at a glance (something's not plugged in correctly, etc), you can always refer to the user manual included with your motherboard.

How to Read a Red Light on a Motherboard

There are four main indicators newer boards have, and the red light will be located next to each label. Those are:

BOOT: A red light near the BOOT indicator means there is something wrong with the boot devices, which would be the hard drive. More specifically, it’s the hard drive where the OS is stored.

VGA: A red light near the VGA or GPU indicator means the graphics card is not detected or seated properly.

DRAM: A red light near the DRAM indicator means that a RAM module has not been seated properly. If you can see that side clamps on either side of a RAM stick are not locked down, that's probably the issue.

CPU: A red light near this indicator means the motherboard does not recognize the CPU, which could mean a number of things. It’s possible the CPU is not plugged in correctly or one of the pins is bent. It could also be the CPU fan is not plugged in. Finally, a dead CMOS battery can also cause the red light to trigger.

Important:

Older motherboards (made before 2015) will have a single red LED to indicate there is a hardware malfunction, but they don’t include any information as to what’s wrong. To find the culprit, you will need to remove all of the hardware, leaving no connections, and then plug them in one-by-one.

What Does a Red Light in CPU Indicate?

Each motherboard LED tells you where the problem is, but not necessarily what it is.

The red light near the CPU label indicates that something is wrong with the processor, and it’s one of the more common reasons why you will encounter the red light.

Here are some reasons why the CPU indicator would trigger:

  • It may not be seated properly, which can mean it’s not plugged in correctly or the pins are bent. 
  • It may also mean the motherboard’s power cable is not plugged in correctly.
  • The CPU fan cable is not plugged into the header all the way.
  • The CMOS battery is dead.
  • The CPU you have installed is defective.

How to Troubleshoot Red Light Errors on a Motherboard

These steps apply to all motherboard models, including older boards without labeled LED indicators.

Always make sure the power of the computer is off, and the power supply switch is set to 0 before disconnecting or connecting any internal hardware.

  1. Disconnect the affected hardware and reseat it to make sure it’s plugged in properly. If you have an older board you can skip this step.

  2. Reset the bios of your motherboard. Most of the time, it’s a jumper that you can short (by plugging in a jumper). You will need the user manual for your board if you don’t know the steps to do this. You might also check the official support website of your motherboard’s manufacturer. Alternatively, you can remove the CMOS battery and leave it out for at least five minutes.

  3. Replace the CMOS battery. A dead battery will trigger a red LED indicator, which can leave you pulling out your hair. You may even consider trying this first before anything else.

  4. If all else fails, disconnect and unplug all hardware starting with the GPU, any hard drives, the RAM, and the CPU. Look at the connectors and pins to see if there’s any damage or debris present. Grime and dust may build-up on an old motherboard which can cause problems. You can remove it by carefully cleaning the connectors with a soft pencil eraser. You should also remove all external peripherals including the mouse, keyboard, external drivers, printers, and ethernet cable.

  5. One by one connect the devices into your computer and try booting it up. Critical hardware includes the CPU and RAM. If you have multiple RAM modules you can leave one plugged in and the rest disconnected. If the computer appears to boot and there is no red light present, even when there is no video, then it’s likely you’ve found the problem. Try booting without the GPU (graphics card), and a single stick of RAM.

  6. If you’ve checked all parts and the problem persists, the problem may be either a defective motherboard, or a dying or defective power supply. In some cases, when the power supply fails, it still supplies power to the motherboard and components, and everything including the system fans will turn on, yet the computer will not boot.

How Can You Tell if Your Motherboard Is Dying?

The best way to tell if your motherboard is dying, or failing, is to follow the troubleshooting steps discussed here. Unplug all minor hardware from the board and attempt to boot with minimal connections.

If the computer still won’t turn on, or POST, then it's likely that either the board or the power supply is the culprit. More often than not, the power supply is the problem, however, if you replace the power supply and the computer still doesn’t boot, you know it’s the motherboard.

In rare cases, you may be able to detect damage on the board, including burnt or defective headers, transistors, and other components. A board that has been killed by a static shock will not show any signs of damage, however.

How to Check if a Motherboard Is Bad

Why Does My Motherboard Have an Orange Light?

An orange light, usually solid, means there is power being supplied to the motherboard, which is normal. Some motherboards may display a persistent orange light, while others will not.

With select computers, the power button may flash different colors to indicate a problem. A solid orange light means there’s a problem with the motherboard, while a blinking orange light means there’s something wrong with the power supply.

FAQ

  • A red blinking light could appear because of a video card issue, built-up debris, or a CPU recognition error. Look to see which indicator is lighting up, if labeled, and run through the steps above. Consult the user manual or customer support if the documentation doesn't offer details about what blinking or solid light patterns indicate.

  • This light could mean that your RAM is faulty or not correctly seated. Check that it's secure and make sure you're putting it in the correct slot or according to the manufacturer-recommended configurations. Also, double-check that you've purchased compatible RAM for your machine.
