their stable although i gotta admit you got me confused with all those colors could have like it better if you would have just write the voltages number instead (like +5v for example) , theres one thing unclear how did you test the +3.3v exactly? and was it when the pc was powered on? , anyway did you have prime95 (stress testing program) running for a while before you checked the voltages as suggested in one of the guides? its important to test the load stablity of the psu as in heavy load the voltages can drop.. sometimes a bit and sometimes alot so if you havnt ran prime95 for a while before you checked em then do so and recheck em , anyway it can also be the graphic card overheating or a bios issue , what graphic card do you have? (so ill be able to tell if it have a sensor) also leave the case open while the pc is powered on and look if the graphic card fan is spinning, and get the latest bios (and just to make it clear as some ppl get confused i mean the motherboard bios not the graphic card one)
