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 loads normally with Turbo Boost disabled, but enabling it causes a BSOD as Windows starts. 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 1TB WD Green SN3000 SSD. I also noticed poor Cyberpunk 2077 performance, around 40–50 FPS regardless of graphics settings, and benchmarking showed the CPU was underperforming. The BIOS has since been updated to version 1836. What should I check next, and is the processor likely defective?

First, check the BIOS version and make sure the board has the latest firmware and Intel microcode. Early 13th- and 14th-generation Intel processors had known voltage and power-management problems that could cause instability or permanent degradation. Updating the BIOS may prevent further damage, but if the processor was already affected, it may still crash as soon as Turbo Boost raises its power and clock speeds. In that case, replacing or warranty-exchanging the CPU is the likely solution.
Collect the actual BSOD evidence before guessing. If Windows can start with Turbo disabled, look in C:WindowsMinidump for crash files and inspect several of them with a debugger. The stop code and the modules listed in the dumps can help distinguish a CPU or memory problem from a driver issue. Also make sure Windows is configured to create small memory dumps if no files are being generated.
Turbo Boost is not an optional overclock in the usual sense—it is how this processor reaches its advertised performance. Disabling it drops the chip far below its normal boost clocks, so the reduced gaming performance is expected. Since the computer crashes during Windows startup whenever normal boost behavior is restored, I would run a memory test, load motherboard defaults, and verify that power limits and voltage settings are on Auto. If it still fails after the BIOS update, contact the system builder or Intel for a CPU replacement.
The low frame rate makes sense if the processor is locked around its base clock. Cyberpunk performance should improve once the CPU can run normally, so replacing the processor may address both the crashes and the benchmark results.
The BIOS is now updated to version 1836, but Turbo Boost still causes a crash. That makes a damaged or faulty CPU more likely, although checking the motherboard settings and crash logs would still be worthwhile.
