Computer won't turn on after power outage
My computer is connected to a surge protector, so it usually won't have
the typical power problems, but I was out today and had left it on. When I came back, the power was off for about two hours and the computer stayed off. I tried to turn it on, but no go. The surge protector is working properly, everything else on the strip works, but no power at all for the tower. I unplugged the whole thing and tried to reset the PSU itself, turning it off, and then on again, when I noticed that when I only had the power cable in, it would emit a faint but extremely audible high pitched noise. I turned off the PSU and the pitch would rise, intensify, then die out. I suspect my PSU is dead, but I hope it's not the case. Is there a possiblity of it being something else? I checked inside the case and everything was plugged in firmly, no lose connectors. I've never had a problem with stability or power supply until today, and my comp is usually on 24/7 for seeding purposes. And what I'm working with: Antec Sonata II with 450W SmartPower Asus A8N5X motherboard |

And what I'm working with: Antec Sonata II with 450W SmartPower Asus A8N5X motherboard The same thing happened to my son's computer a couple of weeks ago. Same case, same mainboard, same PSU, same symptoms, including the high pitched noise. He replaced the PSU with a 350W SmartPower, and his PC is working fine now. So the original PSU definitely had been fried. -- Bob Day http://bobday.vze.com |

Computer won't turn on after power outage
Procedure for a solution has been posted many tmies previously such as
in microsoft.public.windowsxp.general on 7 Jun 2006 entitled "Dead computer" or at http://tinyurl.com/qcvuq Start by breaking the problem into parts. For example, first verify power supply system. From what is posted, nothing says that system is working. This procedure can isolate possible problems to power supply, power supply controller, or switch. Once power supply system is confirmed, only then move on to other possible suspects. First step to a solution was described previously in that other newsgroup. An adjacent surge protector does not do as you have assumed. For example, we traced a destructive surge path through a network of powered off computers because an adjacent protector provided additional and potentially destructive paths through that machine. Meanwhile, surge protector is installed to avoid problems that occur typically once every eight years. Reasons for failure are numerous. Far more than has been posted by speculations here. Find and eliminate a problem step by step. Lights can illuminate; disk drives spin; noises occur; and still any one part of a power supply system could be 100% defective. Get that meter and isolate a problem long before replacing anything. wrote: My computer is connected to a surge protector, so it usually won't have the typical power problems, but I was out today and had left it on.

Computer won't turn on after power outage
This is a troll who searches the USENET archive for "surge
suppressor" and "lightning", and then jumps into the group to preach his misguided sermon about surge suppressors being ineffective.

It does indeed sound like your PSU has failed. The easiest way to diagnose
the problem is to try replacing the PSU. -- DaveW ---------------- wrote in message oups.com...

Bad auto mechanics would also just replace parts until something worked. Even trained auto mechanics discover a problem before fixing it. It costs less. It solves a problem the first time. It takes less time. Possible reasons for failure are numerous. Find and eliminate a problem step by step. Lights can illuminate; disk drives spin; noises occur; and still any one part of a power supply system could be 100% defective. Get that meter and isolate a problem long before replacing anything. Replacing a power supply only on speculation is called 'shotgunning' - a technique common even among inferior 1950 auto mechanics. Use the meter. Save time. Save money. Don't shotgun. |
