Question Upgraded my PC yesterday but I am stumped.

[DirtMonkey]

Yesterday I went out and purchased a Gigabyte A690 MB and an Intel i7 12700 processor along with Corsair Dominator 32GB DDR5 5600Mhz memory. This was all going in my existing tower along with my 3080 purchased a few weeks ago.

Install went well and the system was performing AMAZING for a few hours. Went into some complex games like ARK Evolved and such and played great. Then I went to play a League of Legends with my son and got a BSOD when it tried to load-in. Restarted the computer and tried to go into the game again. Same thing, BSOD. Restarted the computer and now as soon as it restarts and tries to even start loading I am greeted with BSOD almost immediately. the BSOD errors are numerous from IRQL errors to corruption errors and so on. Here is the start of my trouble shooting:

1. Figured it might be hard drive related so I built a bootable Windows 8 installation USB key. As soon as it boots to it, BSOD. Disconnected my hard drives so the only thing that was plugged in was the USB and same thing.
2. Figured it might be memory related. Pulled one of the 16GB modules and BSOD at boot. Swapped the 16GB module for the other one and BSOD.
3. Figured it might be a power supply issue. Pulled my 3080 out of the equation and used the internal graphics. BSOD at the same spot.
4. Figured it might be my capture card or the expansion USB PCIE cards so I pulled them. BSOD at same spot.
5. Disconnected EVERYTHING from the motherboard that I could and BSOD at the same spot.

It honestly feels like I am left with a Motherboard that gave up a few hours after purchase but would love to hear if I somehow am missing something else. Computer components are so hard to do returns on these days. 🙁 Give me your advice on other things to try as I need to get this rectified today. Thanks in advance!

Hi and welcome to the forums!

Could you give a full system spec for the machine? Including any storage devices you may have installed and your Power Supply.

My first question is why would you build a WIndows 8 USB? That machine should be running WIN 10. Was it running WIN 8 before when it started crashing?

When you started pulling things out did you make sure to reconnect all of your power connections?

As of right now, there is nothing hooked up the motherboard. No hard drives, no NVME, no SSD, nothing. The Windows 8 bootable build was just a quick and easy way to isolate the hard drives from the equation. No power was not disconnected from the motherboard and if I had forgotten about something then I wouldn't be able to get to the BIOS settings and wouldn't be able to get to the point of a BSOD. The system boots but is BSOD once it goes past the bios. The only item that is still hooked up the motherboard is my EVGA 750 watt modular power supply.

Have you tried re-seating the RAM or running only 1 stick?

I will also state that I was pretty confident that it was the Motherboard. So confident that I went out and grabbed a replacement one. I will need to build a similar spec computer next month anyway. Well, it wasn't the motherboard as this one is doing exactly the same. Which means it is either CPU or Memory but if it was memory, it would have to be both faulty which is unlikely.

Perhaps put a copy of memtest86 on a flash stick and see it will boot.

Nope, I tried that one this morning but couldn't get it to load to a prompt before it crashed. 🙁

I am going to take the MB/Mem/CPU to the computer shop I bought it at. Unfortunately with it DDR5 and 12th gen, its not like I have extras kicking around like I do with older systems. haha. Part of the frustration!

What is a Gigabyte A690 MB?
Can you provide a link for this?
