Check if the Flash drive is MBR or GPT, it should be MBR for flashback to work.

Extract the download directly onto the USB drive and run the BIOSrenamer while it's on the usb then after move the renamed bios file to the USB drive root.(Don't know why this seems to work for some people over using the BIOSrenamer on the desktop but hey it's worth a try)

I need to definitely check this out I didn’t check if it’s mbr or gpt just formatted fat32

It’s a 32gb usb not sure if that’s the issue

Also after it failed I created an 8GB partition and left the other 20gb unallocated to rule out the size issue
 
Ok so converted to mbr and fat32 copied from the zip file the bios file and renamed it using the tool

Plugged it in held the flashback button flashed for 3 seconds and turned solid green (accordingly online seems to indicate failure )

Not sure what else to do
 
Ok after a few tries it worked flashed for a few minutes and then the light went off (successful !)

Or so I thought not sure if I was supposed to but after about 10 minutes of the light going off I tried putting it on

Here a click (not from the power button ) and then it proceeds to do the very thing it did before the bios flashback

Doesn’t turn on now same rgb flash also no sign of doing anything besides the light during the flashback process like on the Monitor
 
The click is coming from the power supply

And stops it could be the power supply

Unfortunately I have no other one to test

I’d like to make sure it’s the power supply before returning and ordering a new one though

I love PCs but sometimes they can be a real pain. Your problem could literally be anything from bent pins, bad PSU, bad BIOS flash, even something something simple like bad RAM seating.


Although personally, I would start reseating with RAM in the slot according to the manual and also checking if the CPU pins are bent (look carefully, even a single bent pin might be the cause).
Next step, I would start suspecting the mobo. Refurb boards can be iffy.

Actually it’s perfect for the cost, saw a refurb motherboard on takealot have some spare ebucks so might do that on takealot

Try and clear the CMOS lets see if that changes anything.
Turn off PSU and disconnect the power cable from the PSU
Then remove CMOS battery and wait for 10-15 minutes.
Reinstall the CMOS battery and try to boot it up.

If the above doesn't change anything then my next step would be to disassemble everything from the case and remove all components from the motherboard, then put the motherboard on its cardboard box and connect the power to the motherboard then try to power it, check if the diagnostic LEDs now correctly light up for any of the missing components.
If the motherboard included the small PC speaker or if you have a spare from another PC make sure to connect that and listen for any beeps.

If the motherboard diagnostic LEDs are still dead with no other components installed and no beeps from the PC speaker then I would venture the motherboard could be dead.

A single click when turning on from the PSU isn't concerning, that should be the bypass relay.
As long as it just a single click sound when turning on or off, not popping sound or other weird repeating sounds.
 
Thanks guys for the help

Will sit this afternoon and see what happens

I’ll post some pictures as well to clarify some stuff when I start disassembling the pc
 
Test with 1 stick RAM and CPU in the socket plus try to use a brand new flash drive in the BIOS Flashback port.

I thought I’d share
While my Corsair H115i stated, 15xx and 1200 LGA sockets only

The stand off’s from the 15xx series worked. Paste spread was even and decent pressure on the cpu itself

My newly installed 12700K was running on idle at 25č, under boot up and web browsing it peaked to 36c.
Click to expand...
With quite a few online computer stores, not to be mentioned here, advising me that the 15xx stand off's simply won't work. I think my thermals are looking pretty good! I haven't touched the bios yet, so I'll still probably undervolt this puppy and return some better temps (room temp is at 21)

The most stupid thing is causing it and I cannot believe this

Took it out the case plugged it in even used the case button wired up and it instantly booted detected cpu and ram all correctly

What on earth is in the case preventing booting up from happening ?

I checked for any obstructions but there’s none

Sounds like a short to me. Check if there are any additional stand-offs in the case that could be touching the bottom of the board.

Also check the GPU alignment in the back of the case - had it before where the HDMI port was touching the bracket and causing a short.

Yea definitely stand offs cause I took the gpu out when testing

Do I remove the stand offs ? Since it’s ATX I think it only needs the bottom and top stand offs and not the middle ones ?

Keep whichever stand-offs the motherboard has holes for. Remove all the others. You want to use all of them because it distributes any stresses and loads across the motherboard - prevents anything flexing or breaking under the weight of a CPU cooler, GPU etc.
