First I would say "thank you" to "dren99" and "BBBKKKSSS" for responsing to me about my computer problem. Please refer to the link below for the problem: http://web.wenxuecity.com/BBSView.php?SubID=computer&MsgID=40088
Regarding the Vcore (Is that exactly the voltage of CPU?), I did not make mistake, the AI booster did show that it was 2.5000V. I have monitored since you responsed to me, it has been around 2.500V even sometimes 2.62V. I re-set up the BIOS to make the Vcore to 1.500V, but after I used the computer for a while it went to 2.600V again. So what's wrong with the Vcore? The AI booster is not accurate? or some other setting is wrong?
Another thing, the CPU fan came with the CPU from Intel. So I think it is good enough to cool the CPU, DO you guys think I need to get another fan to replace it?
I suspect the power supply may not be good. The power supply is Orion XP480, its maximum output is 400W.
Any idea about my computer problem? I will really highly appreciate if any one can give me any help. Thanks a bunch.
