I followed Linus Haswell's overclocking tutorial, but after setting the CPU ratio to 4.8 and saving, it stopped at the first screen. I can't access BIOS either. The CPU voltage was configured at 1.200. I own a Noctua NH-D15 cooler, and I've restarted the computer several times before it would proceed, but Windows would then report errors like 'windows-driver-overran-stack-buffer' and 'whea uncorrectable error'. Please assist.

You gradually increased the speed or set it to exactly 4.8ghz from the start.

Remove CMOS settings. Boost CPU speed gradually. Avoid jumping directly to 4.8GHz.

Disable the CMOS and test with a reduced clock speed.

Reset the CMOS, check if your motherboard has a corresponding button, otherwise remove the battery and wait ten seconds before reinserting it

I started with version 4.6 and it worked well, then switched to 4.8 because the video mentioned an i7 4770K and he quickly moved back to 4.6 to check its performance

Have you ever experienced 4.7 gigahertz?
