Hi, i have an.
Asus h110m_d board
i5 7400 cpu
8 gigs ddr4 ram
Gt 710 2gb ddr3 gpu
Recently, while playing pubg, my system just restarts saying it detected power surge and turned off for protection due to faulty psu. It also does this sometimes while ther is no work load. What should i do? Anyone pls help. When i checked the bios, the 12 v meter is fluctuating upto 10.5 volts and not more than 11.9v.
