|Okay, one day, I used my PC. The next morning, I press the power button, it turns on for half a second, goes right off. Press it again, stays off. NOW, I look into my PC and notice that when I press the power button, the fan jolts a bit, but the green LED goes off...|
When I unplugged the 4 pin ATX cable labeled 'P7', 2 out of 3 of my cooling fans ran, and all devices except the monitor were working!
I messed with some other plugs, and it was only that same problem.
I'm still trying to figure out what the problem is, and what is that P7 for?
I have an HP Pavilion a1240n
