Hello all! Here's the setup: Gigabyte GA-7N400 Motherboard A Power 480 Watt power supply Athlon XP 3200+ (I think) Alright, first things first--this thing is REAL dusty. I am a bad computer parent. This afternoon, I came in and noticed a faint burny odor (could have been my imagination, but I imagine it didn't bode well), but I was in a rush to pay rent, and ran off--returning several hours later to see the power LED on, but to hear no fans on the computer. I open up the box, and I can 'power on' and 'power off', with the LED acting like it's on -- it takes the normal 3 or 4 seconds to hard-shutdown. However, no fans are spinning. I imagine if the power supply went out, no LED would come on, but shouldn't the fan run? Also, on the board itself, the 'RAM LED' light comes on when I turn it on, but nothing else. So, what do you guys think? Is it: Power Supply Motherboard Processor A combination of the above? How best to determine the faulty component? I don't have the option of switching things out with for-sure working versions. Thanks!
