Hi tagertale,

I wouldn't call HP just yet.

Erico gave you the right advice. You have a power supply issue. You should troubleshoot the powersupply first to make sure it either works or not. If it no longer works, you'll have to replace it whether you call HP or not. And since you are out of warranty (I'm guessing based on the age of your PC), you'll not be able to get HP to do this for free.

That document that Erico linked you to will help with troubleshooting the power supply issue. When he said to "reset" the PSU, all that really means is to move the voltage selecter on the PSU from one setting to another. This is fairly simple to do, and if it works, your PC will be happy again.

For reference, here is the document Erico linked before: http://support.hp.com/us-en/document/bph06788

And if your power supply needs to be replaced, here is a document/video that shows how to change it in your PC:

Many technologoes are used including thyristors, MOVs, avalanche diodes, GDTs, and even one very unqiue solution that used a radio receiver to activate protection. But in every case, protection is not defined by a protector. An effective protector connects low impedance to what does proetction - single point earth ground. For the same reason that lightning rods also work.

How to made a protector even more effeictve? Upgrade the earthing and its connection to 'more exceed' code requirements. Because a protector is only as effectve as its earth ground. That sentence identifies plenty of protectors that do not even claim and cannot perform effective protection without also installing a service entrance...

Safety Tips During Power Outage

During a power outage, make sure the problem is not the main switch or circuit panel in your house.

It is good practice to have a telephone that works without electricity.

Avoid using candles, or anything with an open flame. This can become a potential fire hazard. Use battery powered flashlights for light.

During prolonged outages, unplug electrical appliances.

Dress in layers to conserve body heat.

To avoid a potential build up of carbon monoxide, vent fueled space heaters adequately.

Turn on electrical appliances gradually after power is restored.

Downed Power Lines

Do not touch a downed electrical line, treat it as if it were energized.

Stay away from downed electrical lines and anything that they may be in contact with.

Report downed lines immediately to Cleveland Public Power...

The PSU is the most likely culprit, the second-most likely culprit is the motherboard. The third possibility is something funky happening with your home's wiring or some extension cord you may have between your computer and the power outlet (for now you might want to make sure that your case is connected directly to the wall socket if possible)

There's a plethora of things that could be going wrong, but I suspect faulty capacitors in the PSU that are taking this tremendous amount of time to charge themselves up to an operational state. I am working on the assumption here that all other electronics in your home work fine after power is restored.

You could as drspa44 recommended eliminate the power supply being at fault by testing it without being connected to this specific computer (you can connect it to another computer, or use the method he recommended) to simulate a power outage you cut off power to the PSU and then start the computer (or testing device) until the...

Know How You Can Stay Safe and Get Through
Until Power Gets Restored to You

Severe storms are devastating to homes, properties, and lives. These storms can also take down power lines—creating a dangerous situation for all of us, including the linemen and linewomen working hard to get your power turned back on.

How long it takes to get your power restored depends on the extent of the storm’s destruction, the number of outages, and when it becomes safe for utility personnel to get to the damaged areas. There are many steps in the assessment and restoration process—clearing downed power lines; ensuring public health and safety facilities are operational; checking power stations and transformers; repairing transmission lines, substations, and distribution lines; and getting power restored to customers within the various damaged areas.

Be sure to contact your electric utility immediately to report the outage.

We work hard to prevent power outages, but they do happen occasionally. If you experience a blackout at home or work, here are some simple safety reminders:

First, check for blown fuses or tripped circuits that may be the cause of the loss of power. Also, see if your neighbor has power. This will help determine whether there’s an electric outage. Switch off the lights (except one). You can help prevent damage to your electronics and appliances by unplugging them -- computers, stereos, televisions and air conditioners. After the electricity is restored, you can plug them in again. Get updates from a battery-powered radio if it’s a storm or emergency situation. If it’s a hot day, find relief from the heat at a nearby cool center. Keep a fully charged cell phone on hand. During power outages, you may lose phone service, and your cordless phone may also lose power. Keep refrigerator and freezer doors closed. It helps keep the food cool. Before eating food items, check them for...

A lot of people think when they turn off an electrical appliance that it doesn’t use any power. Time to think again, most electrical devices in your home still use electricity while turned off! Crazy! Some appliances never actually turn off, they are still consuming power in a standby power mode. Some electrical appliances in your home aren’t in a standby power mode, but still consume power because the way their power supplies are built. This is called many things, vampire energy, phantom energy, electricity leak, or leaking electricity. Continue reading this go green tip to learn how you can save electricity and save money!

What Electrical Appliances Still Use Electricity When Turned Off

Any electrical device that has an external power supply connected to it will still use electricity while powered off. Such as cellphone chargers, computer speakers, any of those electrical devices with a cubed power supply on it. Also any electrical appliances that have a clock,...

Wondering why that expensive new DVD player mysteriously stopped working? The culprit might be a power surge. A power surge can enter the home, fry the circuit breaker and spread to various outlets in the house. If an appliance is plugged directly into the electrical system, it may not survive the sudden burst of electricity. Surges can also originate inside your house and potentially burn out anything that's plugged in, from your computer to your television to even your refrigerator. In order to protect your valuable electronics and appliances, make sure you understand what a surge is and how you can limit the damage.

What is a power surge?
A power surge occurs when there is a sudden, significant increase in the voltage of electricity flowing through your circuits. In the United States, most electronics and appliances work on 120 volts. During a surge, there's a brief but dramatic boost in that voltage rate, which brings too much electricity running through your...
