HP Compaq Presario SR2013WM ...Power Problems ?

\015 Everything was working fine until we noticed something wrong with the power button .If you turn it off, when you restart it the monitor wouldnt always display so we started leaving the computer on now it wont shut off period or display anything at all.\015\012Also,both fans are running wide open and power will not shut off even when the wiring harness is unplugged from the switch and motherboard.\015

Answers :

Unless the power button sticks or does not pop back out, i doubt the issue is in the switch, but it can be tested by replacing it with a momentary switch from Radio Shack (not an exact fit, but good for testing)
\015\012This sounds like a power supply issue. That would be the first thing to check. If it is NOT connected to anything except the power cord , it shouldn't run unless switched on.
\015\012 Could also be the motherboard, but before you start dismantling the computer , check the obvious. Open the case (usually to screws on the back) inspect all the cables, reseat your ram chips and addin cards.
\015\012Not to scare you ar anything, some of these presarios have bad capacitors on the mother board. coupled with the fact that they are difficult to clean (inside) and airflow is not maximized in the case, they tend to cause the capacitors to swell and leak, losing voltage.
\015\012 When you are inspecting the insides of your case, take note of any capacitors (little cans with crosses on the top) on the main board inside around the CPU fan that are swollen or leaking.
\015\012If you find these in bad condition , i would replace the motherboard.
