No, it is not defective.
No, it is not defective.
Initially, here are the details. The system runs at 12600kf with 4060 8gb and 32gb DDR4 memory, using an ASRock B760 ITX/D4 motherboard with Wi-Fi, 1TB M.2 SSD, and NZXT H1 V1. I built it for a friend and started it by inserting a USB drive with the latest Windows version. Everything seemed fine until I opened Windows Update and updated everything. I installed GeForce Experience to refresh drivers, but the PC froze for two minutes, restarted three times, and entered recovery mode automatically. Startup repair didn’t work, making it impossible to access the OS. I cleared the SSD via BIOS and tried again. During the first 30 seconds, the graphics performance was solid at around 3000 FPS for Geometry Dash, though it stuttered afterward. After about half a minute, the system completely crashed. I suspect a hardware problem, especially since I have full warranty coverage on all components. My main concern is the GPU, but I’m not entirely convinced. Someone could help me troubleshoot further.
