Computer freeze Event 41, Kernel-power

[Brian Babu]

i recently upgraded my computer with a new radeon R7-260X card and a huntkey 700w power supply and my computer randomly freezes up when idle. sometimes when it does there's a sharp screech like sound for a second and everything freezes up. i have to reset the computer when that happens. on my event log there's critical error of source kernel-power, ID 41, category 63.
My computer is a HP Pro 3330 MT. Any help on solving the problem would be very much appreciated as i don't know what to do.

Could be a failing power supply.
