I bought a prebuilt gaming PC that blue-screened after about 20 minutes of use. After spending two days testing the other components in another system, I narrowed the problem down to the CPU or motherboard: Windows crashes during startup whenever the processor's Turbo Boost mode is enabled. With Turbo disabled, the system runs, but performance is much lower and Cyberpunk only reaches around 40–50 FPS regardless of the graphics settings. I've also updated the motherboard BIOS, which is now version 1836. The system has an Intel Core i7-14700F, an ASUS B760M Max Gaming WiFi motherboard, an RTX 5070 Ti 16GB, 32GB of DDR5 memory, an 850W 80+ Gold power supply, and a WD Green SN3000 1TB SSD. What should I check next, and is the CPU likely damaged or in need of replacement?

Check the Windows minidump files in C:WindowsMinidump after the blue screens. Copy the folder, compress it, and review several crash dumps rather than relying on just one. The bug-check information may help distinguish a CPU stability problem from a driver, memory, or motherboard issue.
Turbo Boost is not an optional overclock in the usual sense; it is part of the advertised behavior of this CPU. The 14700F can boost up to roughly 5.6 GHz, while disabling Turbo leaves it operating much closer to its base clock, around 3.4 GHz. If the system is stable only with Turbo disabled, that strongly suggests a hardware, BIOS, power-limit, cooling, or microcode problem rather than a normal setting.
Confirm the exact BIOS version and make sure the board is running a current release with Intel’s updated microcode. Early 13th- and 14th-generation Intel processors had known power-management and voltage-related stability problems, and the BIOS updates were intended to reduce the risk. If the processor was already damaged before the update, disabling Turbo may only be masking the problem, so an Intel warranty replacement or an exchange through the system builder may be necessary.
I updated the BIOS, and the motherboard now reports version 1836, but Turbo Boost still causes a crash.
I’m trying to restore Turbo because gaming performance is poor with it disabled. Cyberpunk stays around 40–50 FPS on every graphics preset, and benchmarking shows the CPU is the only component underperforming.
