B760 board wierdness
B760 board wierdness
New build, in the previous model with a solid power supply. Gigabyte B760 Aorus Elite AX, Intel I7 12700K. It started up to BIOS, that's fine. I began examining components and the wireless mouse froze briefly before the system crashed. It wouldn't reboot after multiple attempts; each time it would cycle through RAM and CPU indicators, typically ending on the CPU light after a few minutes. I verified all connections, swapped RAM slots, etc., but the issue persisted. After a short while, the same mouse freeze and crash occurred again. It boots every 5-10 tries and always crashes. I've used a different mouse and tested various USB ports with the same outcome. I'm hesitant to flash the BIOS since it might cause more problems. Think there could be an issue with the board itself? Any suggestions?
Is your wireless mouse USB controller plugged into one of the black USB ports instead of the red or blue ones? The latter requires a motherboard driver to function correctly. If you're using a wired mouse, consider that first. I might also think the mouse is powered on. A BIOS update could potentially resolve the problem.
Thanks for the reply. I've tested almost every USB port. I don't own a wired mouse, but using a different keyboard and mouse setup didn't help. However, there was a further step. I removed the graphics card and connected it directly. It started up, but the mouse stopped working immediately without crashing right away. After waiting, I noticed the screen fragments in some areas. Then it crashed completely. During repeated attempts to boot, occasionally the LEDs indicated it should have booted, but no video signal appeared. I tried another graphics card, and still nothing. It hasn't booted since then—just cycling lights. This is really confusing. I'm still wondering if the issue lies with the board itself.
Perform your tests using integrated graphics to resolve one part of the problem.
Run memtest86 or memtest86+ if possible.
They start from a USB drive and do not rely on Windows.
You can obtain them from:
MemTest86 - Official Site of the x86 Memory Testing Tool
www.memtest86.com
MemTest86+ | The Open-Source Memory Testing Tool
www.memtest.org
Memtest86+ is a free, open-source, standalone memory tester for 32- and 64-bit systems (supports UEFI & BIOS, USB boot).

If a complete pass runs without errors, your RAM should be fine.
Inspect for any bent pins in the CPU socket—it can lead to various problems, mainly related to memory.
It’s very simple to check.
Be thorough, as these issues are often hard to spot.
If you notice one, attempt to fix it using a needle.
Removed the board and reassembled the old system, so I’m not in a hurry. I’ll inspect the CPU carefully to prevent similar problems. However, there appear to be too many symptoms for a straightforward solution. The continuous looping of the LED is unfamiliar to me, but it managed to boot into BIOS several times and all devices functioned correctly. I plan to conduct some bench tests.
