Hey all,

Looking for some advice, or tips on what I may have overlooked while upgrading my pc. I might be going slightly insane or maybe i just need to return some faulty things.

First the issue: no graphical output. Pc goes through boot process, and stalls at the VGA stage when it comes to the motherboard indicating lights. Then after ~20 seconds it restarts the process and again passes the CPU, DRAM stages to stall again on VGA and no output to the monitor.

Everything seems to have power, all fans on, cooler pump on, Gpu lights and fans on, all rgb lights up etc etc.

So what i've tried so far:

Removed graphics card entirely and tried the motherboard ports for display. Tried both hdmi and display port outputs on both mobo and gpu and no change. Tested the graphics card on a separate device and that works fine. Changed both cables and monitor tested on and no change in behaviour.

Some things I’d thought I’d try too on the off chance they’d work: changed all power connectors from psu (those that came with spares) unplugged all fans, cleaned and reseated cpu. All these I have then retested between each and still hangs on vga stage.

There also appears to be no damage to the CPU, nor any bent pins on the motherboard that I can see as this was my first big worry.

My suspicion is that it’s the CPU as it doesn’t pass this stage even with no GPU in the pcie slot and connected to the motherboard on either the DP or HDMI slot and my assumption is that the integrated GPU on the 7600x should atleast pass to boot and bring up the bios screen. Thoughts?

For clarity here is the specs:
Ryzen 5 7600X
ASUS ROG Strix B650-A gaming WiFi
2x16GB Corsair Vengeance DDR5 RGB 5200MHz
Corsair RM1000x PSU
NZXT Kraken X73 cooler (old - but with new AM5 mounting hardware due to its otherwise incompatibility)
Palit RTX 3080 GamingPro GPU (old)

I do have access to a separate intel 8700K rig that I can use for some testing - limited to just the GPU really due to switching to both AM5 and DDR5, essentially the rig from which the GPU came from along with the cooler.

Any ideas? Or do you all think I’m looking at a CPU/Mobo return? if you need any additional info let me know!

Thanks everyone.
 
Are you sure the RAM is in the right slots according to the manual?

Can you take a pic of the innards with everything plugged in?

How long have you waited for it to boot? DDR5 systems can take a very long time.
 
Hi sure thing:

The RAM is in the correct slots and I have tried will just a single stick too which i should have mentioned. Ive tried leaving it for ~20mins. Sorry for the delay. Had to set up and imgur account!

Edit: sorry post was hidden! Amateur on imgur...

Unfortunately, I can't see anything obvious that you missed. Only thing I would say is that you have a lot of stuff plugged into the board there, which increases the likelihood of a problem.

Shouldn't make any difference, but you could try reset the CMOS, or even flash the BIOS if you're feeling foolhardy.

Did mounting the cooler go smoothly? Overtightening can sometimes cause problems on AM4, so might apply to AM5 too.

Edit: have you used all the power connectors on the top left?

I’ve just unplugged all the unnecessary cables and gave it another go and sadly no change. I’ll check the manual regarding the CMOS as I don’t know if this voids anything when it comes to returns but will try!

yeah the cooler mounting was fine, luckily I had heard this about just AMD CPUs in general and with the additional mounting bracket from NZXT that I had to get from them I was a especially careful, if anything it’ll be too loose!

Thanks for your ideas anyways. I think I’ll just have to return both mobo and cpu for replacements and just have a sad few weeks of no games!

Nah, pressing the clear CMOS button won't void your warranty. This is a standard troubleshooting measure and very common. You can pull the battery if you prefer, same difference.

Flashing the BIOS on the other hand, they might not be keen on you doing this (I wouldn't voluntarily say if you tried it), but it's also a standard procedure, does sometimes work (especially on newly released boards) and you're not 'modding' anything.
 
Unfortunately this also didnt work . I pulled the bbattery waited 5 mins and replaced it and tried again.







Also i dont know where id start with flashing the bios with no display output so i think id rather return the cpu or mobo or both And they can test themselves!



Oh and thanks for your help btw :)

Probably better off pushing the button, pulling the battery for 5 minutes is unlikely to be enough.

About the flash: it is possible because you have bios flashback feature, but fair enough.

Ahh ok i tried the instructions in the manual because there is no button. Have to short two pins on the board to clear it. Sadly same outcome
 
I have a B650 and the first thing I did was flash to the newest BIOS using flashback, did not even look at what version it was currently on or power it up, just flashed it. Looks like the board has flashback so I would update the BIOS which should not void the warranty, you will probably need to update it a lot over the life of the PC as it’s a newish platform. You don’t need the PC powered on to flash, just must have the power cable plugged in. Its hard to tell if flashback is working as the LED is behind the shroud and it takes a few mins to finish, then it restarts.
