HELP! Is it GPU or MoBo?

[tonylin1115]

Hi guys, 

First time poster here, I'll get right to the point.

So I got a new build with 3700X, Asus TUF Gaming B550M Plus WiFi Mobo, Gigabyte Windforce OC 2070 Super, 16 GB Corsair Vengeance 3200MHz, and Silverstone ET700 PSU.

I have tested outside the case, and it posted via HDMI. However when I got those all installed in the case. It won't post and started showing VGA POST error.  As shown in the link below

However since then, after like 10 times of unplug and replug, it finally POSTed. And I got Windows installed and all seems to running fine. UNTIL I went to the BOIS, to tuning my case fans curves, after I was done and restarted the system. It got stuck in the "bootloop" with VGA post error again. (Sorry haven't got it on camera.) The system bootlooped 3 times, then It'll take me to the Windows BOOT manager telling me that the system didn't boot correctly would you like to restart.

After I selected restart, it got into the same bootloop AGAIN. At the third time of this "bootloop loop", it finally got back into Windows. However it wiped out almost all the programs and drivers that I installed, only thing left was Chrome, and Network adpator driver which was installed via windows update (Thank GOD). 

 

 

So yeah, where do you guys think the problem is, is it the GPU or the motherboard? (I think it's more of the GPU) or compatibility issue even (does it still happen with modern day hardware?)?   Or anyway I can test those out? PLEASE help.

 

Thank you in advance! 

 

FYI: I don't have a spare GPU to test it out, it's my first desktop build.

I don’t know.  The way to find that out would be to make sure the gpu is known good.  The problem is it could still be software because of a bios thing or PSU because of a power thing.
 

Important tip:  if you’re breadboarding trying the gpu outside the case can be useful.

 

If you pull the gpu and boot off the iGPU does it work?

it's a Ryzen 3700X, it has no iGPU

So how did you test it without the gpu?  Unless you Diddnt , in which case the mobo and gpu were both working as a breadboard.  That means PSU is also probably fine too.  Am still doubting either the gpu or the motherboard.  Are you trying to use hdmi inside the case as well? Or are you going with a different port for the monitor?

When you post to bios you don’t test drivers for the gpu.  Drivers are still on the list and seem most likely to me atm.  Doesn’t mean gpu or mobo are out though.  Motherboard is dead new so it could be a motherboard driver incompatibility that isn’t well documented yet.

I didn't test without GPU, I did however tried with motherboard's DisplayPort, and that actually "POSTed" without showing VGA Error, but obviously, it has no iGPU, so no actual output. it's working now, but I'm just worried if it'll happen again, hence why didn't install any games on it yet. I'm using DisplayPort since Gsync.

So it’s working.

Yeah, it got back into Windows in the end. but It wiped out 90% of the SSD. 

I'm worried if it does it again.

If it’s working the gpu and mobo are by definition fine.  They’re working.  What sounds to me like what happened is windows could tell it was a software problem and started randomly deleting/replacing stuff until it hit the thing that was causing the problem.  It was down deep so it did a lot of deleting.

I don't think Windows will do that for you, even if it does, it should tell you that it went back to recovery copy. 

And things I installed was: Drivers,  Chrome, Ryzen master, Geforce experience, Display Fushion, Telegram and MS Office. I don't think any of those will cause bootloop

Drivers can.

Yeah sorry, it happened again today. it was Windows Auto-repair. It seems happens every time I tweak something in BIOS

I have read that Ryzen CPU's sometimes do not like Corsair RAM.
