Ok good info, your cpu temp in bios 129f/54c is high because in bios your cpu is at idle so that is high for a idle temp and is one problem, but remember before you checked a cpu temp with Everast and it reported 100f / 38c that would be a very good temp so we need to decide witch is the correct temp before we fix something that may not need fixin.
I will explain more, 129f/54c cpu temp will not cause your problems by itself but that temp could rise to instable levels when playing games or other cpu intensive tasks.
I suspect a bad software read from Everast or a bad sensor read in bios
Try this unscientific test, let the computer off for 3 to 4 hours then make a note of the room temp, then go directly into bios and read the cpu temp do this as quickly as possible. Take note of the cpu temp and compare it to the room temp. In my experiments the cpu temp rises 3c to 5c from the time it takes from cold start to I get to bios and read the temp, anything else is just a error.
My point in your case is if you get a 3c to 5c differance or something close to that then bios temp is correct and you should clean and reapply themal paste to the heat sink (artic silver5 preferrable).
Also your 5v is right on the edge of spec I will look into that a little more and post back but we may also need to confirm this reading. If that reading is true the power supply would need to be replaced.
