Just set up a computer for my grandmother, having built a few PCs myself, but when looking on the bios, it says the voltage is at 1.440 v, and idle temps are at around 40. This is quite high for idle, even with the super crappy bundled fan. Surely the voltage is too high?

Have you installed all the drivers yet? (not the crappy generic ones that come with windows) As far as voltage it really depends on your cpu, every single cpu is unique and so you have to test it for you self. However I have lowered an Intel T9400 from 1.25V to 1.125V, I lowered a Llano A8-3800 down to about 1.2V, So I would think 0.1V-0.2V is most likely the range to look into. You can also use a program like AMD's PScheck to change the voltage table in windows and do all sorts of neat tricks...

You can always try lowering the voltage. AMD and Intel always have the Voltage set higher than needed due to many factors. Just lower a small amount at a time and then stress test to make sure it is stable then lower it again till it crashes then raise the voltage a notch or two above stable where it starts to be stable just for a safety margin..

Hmm, just ran Windows experience index, and other things, and for some reason, the Radeon graphics don't seem to want to work. I can't raise the resolution above 720p, it won't do aero (w7), and it scored rock bottom 1 on wei

Here are the links.. Here are the chipset drivers (works for windows 7-10) http://support.amd.com/en-us/download/chipset?os=Windows+10+-+64 and then just click download next to where it says "AMD Chipset Drivers"

Then for your APU from amd.com or even from the chipset driver page look at the top right side you will see "Drivers + Support" put your mouse on that and it will list a bunch of stuff, look for "Latest AMD APU Drivers" and select your version of winodws then download it. Fairly easy...
