Here's the deal. A few weeks ago my computer stopped turning on. The indicator light on the power supply would jump on as soon as I plugged it in, turn off as soon as I pressed the power button. Just tonight I did a little research into the problem and find its a bit more complex. I unplug everything, plug in the power supply and start hooking up cables to the power supply, 2 hd's, a disk drive, the motherboard, fans and everything is going fine until I plug in the 4 pin processor cord. A little pop, everything goes dark. My question is, is it the processor, motherboard or power supply and is there a sure way to figure this out with nothing but a 2 pin voltage meter from radioshack and my wits? Furthermore, this is a Celeron D- 3.5 ghz, dvd reading, cd burning, linux running rig from 2006, suffice it to say I'm a student looking at a move in the near future. $300 a month, $150 in my "pocket". So the question is, motherboard, power supply, processor or modest priced laptop?
