 Posted: Fri Aug 07, 2009 3:21 pm Post subject: Power LED flashing while PC is running. (Resolved) |
 |
|
The front power LED on my tower flashes all the time now. I don't know when it started, and I can't find any info on why it would flash while the PC is running fine, all my drivers are installed. Rebooting doesn't fix it, it's not overheating and I'd like to avoid formatting to see if it stops from that. Anyone have this happen to them before?
I'm using an e-machines.
mobo model number: K8MC51G

| maybe the cables in your mother board are not connected properly, sounds like someone mixed up clables and connected your main LED into the processing data LED slot |

They're connected properly. I've checked them, and even reconnected them. The drive busy light still properly flashes when it should as well.

Encounter this a few times and each time the outcome is different.
One machine was a faulty psu
The other was a bad hard drive cable.
Do the HD led and Power Led blink in unison? |

No, the power LED blinks as if it was a blinker on a car, on and off steadily, no noticeable speed decreases/increases. The PSU is getting old, but there are no other signs to indicate a bad PSU.

Im really leaning towards a bad PSU, if it suddenly doesn't work and it's a flashing light then its the PSU or some hardware component failing.

Typically a flashing power LED means the computer is in a low-power state such as standby. Since that obviously isn't the case, and it shouldn't be a wiring issue, I'm stumped as to why it's happening. I'd just say ignore it, it's probably just a glitch, if it bugs you too much disconnect it.

Doesn't seem very plausible. A flashing power LED denotes a low-power state, not hardware diagnostics. The motherboard wouldn't know the state of the PSU because a 24-pin ATX connector doesn't have any diagnostic pins, and if the PSU was failing there'd be many signs he'd notice. |

I got an Idea which sounds pretty stupid but here goes.
Put your computer on Sleep, or Stand Bye...
Check if it the LED flashes or stay's solid...
If it stay's solid then there mixed up.
Then I'd say its a Window's / Driver error...
But if it still flashes then I don't know   .

Actually, now that you mention it I never noticed it until I went into standby on accident one day, and due to my pc being a piece of shit I had to unplug it to regain any control...
@swat: I'll try that later and see what happens. :3
Thanks.
Edit: Just went into standby, it continued to flash, but became solid after leaving standby. I guess forcing it off last time it was in standby fucked it up.
Thanks everyone, closing this.
