I Really Need A Hardware Tech For This One

I turned off my computer (Vista Home Premium 64BIT) and when I went to turn it on, the power button will light up and blink slowly but the computer will not start?

There is no 'spin up'?

Holding down the power button, (sometimes for almost 30 seconds) will shut the pc down but no matter how often I try to power on .. All I get is the slow blinking power button?

I've unpluged the pc for as long as a day .. same results!

The pc did this exact same thing last week but after shutting it down for an hour .. It started normally!?

Does this indicate a dead psu (power source)?
(power unit fan doesn't start?)

I've had harddrives go but the psu would still start up?

I have no idea where to go from here?

The slow blinking power button is exactly what the computer does in sleep mode but it wasn't in sleep mode?
(I shut it down)

Mouse movement nor keyboard movement has no effect.
(Just in case it somehow goes into sleep mode when powering on?)

PSU?
Other hardware?

I can't even insert a rescue disc because .. nothing but the blinking power light comes on!



I went into the case to look around and found this black and white wire connector with a GP tag.

I looked for hours and couldn't find a place where it might connect?

It may not have been connected in the first place.

The connector end was laying under the processor fan and there is no place for a connection anywhere near there?

As (I hope) my pictures show .. the wires are .. one black and one white.
(two 'tiny' little slots for pin connection)

The other end of the wire runs under my cards and connects to the far right of that white connector you can see at the bottom left.

Looks like it connects to the motherboard?


I REALLY need some advice on this one folks!

Thank You.
 
The first thing I would do is reset the cmos. Do this by unplugging power from the power supply, then remove the cmos battery that is on the motherboard, press the power button on the case a few times to discharge any remaining power and then wait 5 minutes. Reinsert battery, reconnect power and try booting up. If it still reacts the same, try a different power supply.

Is this a store bought or custom built pc? Is it a Dell machine by chance?
 
It sounds like the PSU, a quick voltage test could prove/disprove this theory.

Johnb35 what is the reason for resetting the CMOS? I wouldn't have thought this would be beneficial, maybe I have something to learn?
 
Sometimes resetting the cmos will solve issues like this. Sometimes, meaning talking like less than 25 percent of the time. But to be honest, it does sound like a psu issue.
 
I can't thank you all enough foe responding!

I am running again but I am not sure if the problem is fixed,
(Afraid to shut down to see)

This same problem happened about a week ago and I shut down for an hour and everything returned to normal?

i replaced the CMOS battery yesterday and let the pc sit until now and .. here I am!?

I wont be sure if the problem is gone until I try to power on next time.
(Maybe not even then since the pc ran normally for a few days after this last happened?)
 
Well, after unplugging for 24 hours the pc started normally.

Shut down after about 4-5 hours, tried turning on today- .. back to blinking light! 8(
 
Your best bet is the power supply, I had a similar problem, but the light on my power button didn't turn on whatsoever. Popped in a brand new one, and problem solved.
 
This problem is driving me nuts!



Again after sitting unplugged overnight .. The pc is running again!?



I KNOW that when I shut down though .. It Will Not start right back up!



Minimum of 12 hours downtime before it will boot again!



It will run perfectly now (and has been) for hours on end without a glitch!?



If it were the PSU .. The psu Would Have to Shut Down in the 6 to 8 hours that I am running?



Same with a bad MoBo, capacitor.. any hardware failure?



I just don't get it!



I can run for hours now but on shutdown .. back to the slow blinking power button!?

I just don't see how this could be a hardware failure?

I have been powered on for over 6 hours now without a glitch!

As a matter of fact .. it ran for over 12 hours the last time without a glitch .. until I shut it down!? 8(
