Battlefield V loading textures and buzzing sound
Ground electric socket we only see in the bathroom and kitchen so most people do not have that option and all is fine on a normal socket for them. A protected socket is a good thing if you get hit by a lightning storm or some other over current on the local network like a surge of a breaking toaster oven etc this can cause problems if not protected.
The CPU is about 50% to slow for BFV if compared to the minimum recommended FX-8350 or 6600K CPU speed. So the best you can do is improve the cooling of the CPU, lower the case temperatures (add fans), overclock the CPU a little or upgrade it completely if possible (like an Intel Core i7-4770K). So besides a slow game caused by the CPU a low quality or failing power supply unit (PSU) can also halt the system unexpectedly.
On the software side of things just kill everything running in the background (apps and software / mouse and RGB software and monitoring tools everything!). Update the chipset driver again, defragment the HDD or consider an SSD. Look for motherboard BIOS update. disable windows update after its completed for 7 days. etc...
