I'm not very familiar with Akasa, but if I remember correct, that's a fairly decent PSU mainly found in the UK?

Can you download Sensor's View Pro (in my sig) to check voltages? You can also check temps with that. Post your voltages, and also idle temps. I'm thinking at this point is either PSU is going South, or your video card is getting rather hot.

Hi
The +3.3 is showing 1.52V

then you have a problem with your power supply
anything below 2.95v is out of spec
