gigabyte So I just built my new Mini ITX System...

Duneram · September 13, 2021

So about a week ago I built my new Mini ITX System in my brand new V8 Case from Jonsbo. I was pretty excited as this was my first small form factor built ever and I just like to building Computers so yeah...

I built the System, it booted and I installed Windows, etc. Upgraded my Motherboard Drivers so on and so forth. I then benchmarked it and basically checked if it was stable during heavy loads which it was and went on to play some games.

The thing is next day it just wouldn't boot. I was wondering what was wrong and unplugged my PC turned it back on and it just worked. That got me curious so I started the System up shut it back down and tried it again. Same Thing, No Signal No RGG was flipping on in my Case, etc. only thing signaling that something was going on was that my System Fans were Spinning (including the Fans for my AIO) but nothing seemed to work. I then continued to update all my drivers if any were available, reinstall some of them, and even updated my BIOS to the newest version. That didn't do anything which meant taking the System apart to check for any faulty wiring etc. After like a good Hour I triple-checked everything still the same problem. I then continued to rip out every single part that was possible to see if the problem persisted. So I unplugged my GPU (A RX 6600 XT Saphire which I bought from a scalper) tried to start again etc. nothing worked. After a bit more troubleshooting checking my Bios etc. I called Gigabyte up and told the whole story to the Support there which was just as baffled by the Problem like I was. The support guy then asked me to switch PSU's which he patiently waited for (which was like 30min so Props to that guy) and again Same problem. The PC would boot once function completely normal and then when shut down just not reboot. After like 3 tries, he said he would forward my problem to Taiwan and see what they could do about it and that's where I'm at. So my question is if anybody has experienced a similar issue and if there's a way to fix it?

My System Specs are:

- A B550I Aorus pro AX

- Ryzen 5 5600x

- and AIO from Artic

- an RX 6600 XT from Saphire

- 16GB of RGB Vengeance Ram from Corsair

- A 750 Watts PSU from Corsair (SF750)

- A 1TB m.2 SSD from crucial

- All installed in the V8 from Jonsbo as said

So thanks for reading the post and any help is greatly appreciated :)

Try bypassing the case's power button. Does the problem persist if you build the system outside the case, and start the system by bridging the power button pins (or if you leave it in the case, unplug the power button and boot the PC by shorting those pins)?
