[SOLVED] PC won’t POST and red CPU light is on ?

[Jaydenisgood]

I recently built my pc and after starting it up it won't POST on my monitor, I am having multiple issues and have tried everything at this point to no avail. I have flashed the bios button, updated the motherboard, tried just the cpu and motherboard, we have tried everything. Multiple issues are happening along with not POSTing. The red CPU light is on consistently,

I am able to power on the computer using the power button but I can't power it off using the power button. Also none of the ports on the 10 are working either. No clue what's happening I'm looking for any help

• CPU: AMD Ryzen 5 7600X
• Motherboard: MSI MAG B650 TOMAHAWK WIFI
• RAM: Corsair Vengeance DDR5 32GB
• Storage: Crucial MX500 1 TB SSD
• GPU: NVIDIA GeForce RTX 2070 Ti
• Power Supply: Corsair RM650 80+ Gold
• Case: NZXT H5 Flow

watch this video... by "mikesunboxing" follow it and it should help.. with the bios flashing.. i know you tried to flash bios already. but sometimes it does not take the 1st time..
follow the video exactly..
paying attention to how the "file is renamed"(many peoples when showing how they tried to flash , they thought they changed the name,but they ,forgot to make sure the the extention changed. and their names read as "msi.rom.xxx"(x=orinignal file extension), its easily missed, also you have to make sure the correct usb slot is used,.
when the flash is done, install cpu and ram and reboot. it should take a few minutes and a few reboots (as it will be memory training and checking itself.. this is normal.. if its still on the red light after repeated boots.. then it could be an issue with your CPU (if thats the RED light).

also a sign to look for when rebooting. it watch your keyboard. if the computer is gonna boot the "numblock" will light up (and keyboard if you have rgb keyboard).

This is the video I used

I made sure the file on my usb stick is msi.rom and confirmed it to be .rom. I installed it on my pc and waited for the flashing to finish. I have been rebooting my pc a few times and am having the same results. I am letting it run for 2-3 minutes and then turning it off and back on. Red light still on and the IO ports are still not working

hi... ok,. there is a few things that could be making the red light still show.. either the bios flahs update did not take.. (did it do the steady flahing led ,near the flash button, when flashing.. or did it stop immediatly? you can try again using a different usb stick.. as msi boards can be fussy about what drives are used..

also try unplugging the 8 pin cpu connector and reseating that. and the same with the 24 pin... and then remover the cmos battery for 5 minutes and then re instert. clear cmos and try seeing if that helped. if not try flashing again.. but try a different bios (by this i mean when you downloaded the bios from the msi site.. you could try and older bios. and see if that helps. as sometimes the bios'es dont take.. especially "betas"

The led next to the BIOS button consistently flashed for a few minutes. I will try the other things you have suggested. I’m going to use a SanDisk 256gb flash drive as it’s the only other one I have but it’s newer than the other one I used

Hey Steve do you think I should download the BIOS for the 7000 series? I am downloading it for the 9000 series I’m wondering if it’s not compatible maybe? I’m not sure I’m new to this

 

[steveb1976]

yes try the one for the 7000 series. , i dont think it would have cause the issue.. but sometimes some motherboard companies. recommend that people must upgrade bios's in a certain way.. .like i had a few asrock and giagabyte boards that "said i had to flash to a specifice bios number ,before attempting latest. and if you skipped it, it could cause issues. and there was a bios firmware accross all board that then updating... it could said issues. and that the pc would have to boot a few times before sucessfully booting into windows

I think I’m just going to have to take it to a shop on Monday, I have tried everything you’ve said and multiple different BIOS, I took out the CMOS and waited a few minutes, I tried 1 ram, I have done multiple reboots, nothing is working but I will let you know what they say the problem was!

 

[steveb1976]

the shop would be the best bet. as they can physically see the board and parts. they might see something we cant ..
sorry i was not able to help you..

I called someone today and told them everything I did and they told me I should replace my motherboard. I replaced it tonight and it worked no issues. Thank you for the help Steve! Unfortunately nothing would’ve helped haha

 

[steveb1976]

your welcome. its a shame that you had to buy another motherboard. because that was faulty. maybe you can get a refund for your original one.. if not sell it on ebay as "faulty" people will buy it,
