Computer does not boot

I have been trying a lot for days but running out of money and patience atm. 

Problem: pc won't boot (looks like cpu) 

Happens every time. 

Bought a complete new ryzen 7 3700x that wouldn't start with my b450 tomahawk. Decided to buy a new MOBO after finding outer ppl with a similar problem. I got the gigabyte x570 gaming x. 

All the fans etc will turn of during boot but get nothing on screen(shouldn't be my VGA since everything works with my old cpu/mobo) 

The thing that seems to happen:

Cpu fan starts up, then cpu is starting up and taking power. Then the fan goes dark for a few seconds and the cpu seems to die down.

 

I think there is a problem here. I don't think my fan should stop spinning for a second. Just can't figure out if it's psu, cpu or mobo. 

 

When my cpu power cable or ram isn't plugged in the fan does not go off but the cpu doesn't seem to turn on either. Only when everything is plugged in does the cpu try to start up before it apparently crashes. 

 

So my system for clarification:

PSU: corsair RM850 gold

Gpu: gigabyte rtx 2060

Ram: one corsair vengeance ddr4 8 gb atm

Cpu:ryzen 7 3700x 

Mobo: gigabyte 570x gaming x

I'd say power supply first. Change that out and see if you get a normal boot up.

I don't think so, as his fans power up. But yes, it could be a deciding factor.

 

Just came to mind, are you sure the 24-pin, 4/8-pin for CPU and 4/6pin for your gfx card a plugged in snugly?

I think you're motherboard needs a firmware update before you can use the 3rd gen AMDs...

Normally not. X570 is 3th gen ready

I can try but this PSU is a month old and 850w should be plenty no?

Yes, gpu clearly indicates it has power, mobo wouldn't start and cpu doesn't start and stop if it's not plugged in. It will just not start/ just the fan. So everything should be plugged in fine.

Random one for you, but I have something similar from time to time. The cause of my issue is that the Legacy PCI mode gets disabled in the BIOS somehow, and I have to plug in my old GTS 450 to get it to boot into the BIOS. I can then save and exit, and put my regular GPU back in until the issue re-occurs. If you have an old GPU, or can use the on-board VDU (if it has one) then get yourself into the BIOS and hunt for a Legacy PCI mode.

it really shouldn't be a gpu problem. The same error occurs with just one ram and the cpu put in. And the gpu works fine on my older mobo/cpu

Power supplies can go at any time. I'd switch it and see before going further. At least you can check one likely source off the list.

but it still works with an older mobo/cpu and provides power for the fans and lights. So is it dead?

TEST it. It could have enough power to start the fans, but not the whole motherboard.

Use an old one that is laying around...

 

Or have a multimeter?

unfortunately not, can maybe borrow one somewhere. And I bought htis one because my old one wouldn't do anything at all with my new stuff: 550W

Problem got solved (not sure how I can close this topic)

 

The fan turning off wasn't really a problem after all. new mobo had trouble finding my screen. Moving my gpu to the pciex16 instead of the 4 solved this issue. My mobo read that one standard and couldn't find the other, at least not easily.

 

Fair warning though for the B450 tomahawk, I would not recommend using 3th gen amd processors with them. If you have to upgrade both mobo and cpu definitely go for a X570 at least. All my problems started with that mobo, it might work fine in the beginning but problems with the cpu are likely enough to occur.

thanks for the help people.

Exctly what I said... You MIGHT need to do a BIOS update. Not all B450 boards have the latest BIOS versions...

Hello,


The following AMD support department knowledgebase article might be of interest to you:

 

AMD Knowledgebase Article # PA-100, "Unable to Boot New Desktop System Configured with AMD 3rd Generation Ryzen™ Desktop Processor, and AMD Socket AM4 400-Series Motherboard"

 

Basically, AMD will send you an older, compatible processor to use with the motherboard to flash its BIOS.  You have to return the CPU to them, though after ten days, or you will be charged for it.

 

Regards,

 

Aryeh Goretsky

This is exacly the problem I was having with my new Gigabyte X570 Gaming X MOBO. I pulled it all apart and was at the point of sending the board back. Thought it was weird the fan stopped for a second on startup too, and possibly related. It wasn't SImply moved the gpu to the pciex16 instead of the 4 as above and it all worked beautifully! Still doesn't explain why the native HDMI didn't work when I completely removed the GPU. Flaw in the BIOS if you ask me. huge thanks to the forum and Antdrioite though.

I see this is an old thread but for future surfers, this is what I use to test PSU's. It's cheap and works well.

which CPU model do you have? not all of them have integrated graphics so it could be that.

      Hasleo Backup Suite Free 5.4.2.1 by Razvan Serea Hasleo Backup Suite Free is a free Windows backup and restore software, which embeds backup, restore and cloning features, it is designed for Windows operating system users and can be used on both Windows PCs and Servers. The backup and restore feature of Hasleo Backup Suite can help you back up and restore the Windows operating systems, disks, partitions and files (folders) to protect the security of your Windows operating system and personal data. The cloning feature of Hasleo Backup Suite can help you migrate Windows to another disk, or easily upgrade a disk to an SSD or a larger capacity disk. System Backup & Restore / Disk/Partition Backup & Restore Backup Windows operating system and boot-related partitions, including user settings, drivers and applications installed in these partitions, which ensures that you can quickly restore your Windows operating system once it crashes. Viruses, power failure, or other unknown reasons may cause data loss, so it is a good habit to regularly back up the drive that stores important files, you can at least recover lost files from the backup image files in the event of a disaster. System Clone / Disk Clone / Partition Clone Migrate the Windows operating system from one disk to another SSD or larger disk without reinstalling Windows, applications and drivers. Clone entire disk to another disk and ensure that the contents of the source disk and the destination disk are exactly the same. Clone a partition completely to the specified location on the current disk or another disk and ensure that the data will not be changed. File Backup & Restore Back up specified files(folders) instead of the entire drive to another location to protect your data, so you can quickly restore files(folders) from the backup image files when needed. Incremental/Differential/Full Backup Different backup modes are supported, you can flexibly choose data protection schemes, which can improve backup performance and save storage space while ensuring data security. Delta Restore Delta restore uses advanced delta detection technology to check the changed blocks on the destination drive and restore only the changed blocks, so it has a faster restore speed than the traditional full restore. Universal Restore This feature can help us restore the Windows operating system to computers with different hardware and ensure that Windows can work normally without any hardware compatibility issues.
