No Power on an HP Pavilion PC Desktop b> Desktop computers are simultaneously more complex and easier than laptops when it comes to troubleshooting. There are more physical components on a desktop, so locating a specific troublesome part can be tricky, but working inside of a desktop computer is straightforward compared to opening and fiddling with a laptop. Power problems are always hardware problems. There are a few simple, preliminary steps to troubleshooting, but power problems often require opening your computer and having a look inside.
The Basics Unplug everything from your PC except for the power cord. Try turning on the system and look for lights on the front, then on the back. When the power supply is on (receiving power), the small light beneath the plug turns green. If this light doesn't come on, the problem is either connected to the cord or the power supply. Try swapping power cords with the monitor cord to isolate the cord as the source of the problem. Look closely at the voltage selector and make sure it's set appropriately for your country -- 110 in North America and 220 for most other regions. b> The Socket b> Unplug the power cord and switch the voltage selector to the opposite setting. Wait five seconds, then flip it back. This ensures that the switch is engaged. Plug in the power cord again and try turning on the PC. Check the outlet to make sure it's working, and plug your computer direction into the wall socket (remove it from any surge protectors or power bars). Check the power button. If it sticks when you push it, it may not be making contact to engage the system power and will need to be replaced. If the button is going in and out freely, you've done about everything you can do from the outside of the computer. It's time to go inside. b> Open it Up b> Unplug the power cord and hold down the power button for five seconds. This clears all electrical charges from the circuitry and makes it safe to open the computer. Remove the side panel from your system. This process varies a bit from model to model -- some have one or two captive screws on the back of the system, some have an easy release button. Check your manual. b> Power Button b> Locate the power button from the inside and trace the cables to where they plug into the motherboard. Lift up on the connector and then push it firmly back down. Plug the PC back in to its power source and try to power it on. Unplug the computer immediately if the system doesn't power up, and continue troubleshooting. b> Hardware Components b> Disconnect each of the devices in your computer one at a time to locate a faulty piece of hardware. Power cables run from the power supply connect to your optical drive, hard drive, floppy drive (if one exists) and into several places on the system board. This step takes some trial and error detective work and a few minutes: unplug one device, reconnect the power, and try turning on the system. Then disconnect the AC power, plug the device back in and try the next one. If the system powers up at any stage, the device you are unhooking is shorting out the power and needs to be replaced. http://www.youtube.com/watch?v=HJvYGtbwmh8To Replace HP Pavilion Desktop Power Supplyhttp://www.youtube.com/watch?v=VcEFUpZSmI4Hp Pavilion 750n desktop computer basics on this computer b> http://www.youtube.com/watch?v=D8Y2PPMiiB0HP Pavilion Slimline PSU Upgrade Guide This guide compares the Sparkle SPI270LE - 270 watt PSU against the Shuttle PC50 -300 watt as possible power supply upgrade for a HP Slimline.

Sounds like a power supply problem. Usually this occurs when doing work that involves a lot of memory, and progressively gets worse. It has something to do with the crowbar circuit that shuts the power supply whets overloaded; sometimes a trigger-happy SCR. Life is a lot better if you use one of those Ebay power supply testers with an LCD display, but these testers don't draw enough current to trigger a potentially bad crowbar. Best solution I can think of is purchase another ATX power supply 350w or more with the same dimensions. Pay attention to the lenght of the replacement ps to see if it's too long (front to back) to fit in your computer. Hope this helps.
Try this first.
Unplug the power cord from the wall outlet for about ten minutes then plug it back in and see if your PC powers up.
If still no power, the power supply is shot and will need to be replaced, it costs about $40 for the part.
I hope this helped.
Good luck and have a pleasent day.
Verify your fans are for the CPU and case are moving. You can remove the Pc cover and turn on the Pc. Watch the cooling fan on top of your CPU heat sink, it should begin spinning when you turn on your PC. If it doesn't then with the PC unplugged, make sure the connector for the fan is seated properly. From behind the PC you should be able to feel the Power Supply cooling fan moving air. Either of these could cause your PC to over heat and shut down.
This happened to my to my HP Media center Edition PC. I'd have to unplug the power from the outlet, let it stop flashing and the power up again. It would run for a short time and then shut off with the annoying amber / blue flashing light.
I found it was a heat problem on mine - specifically, the CPU cooler. After shutting down and opening the PC, check to see 1) if the CPU fan is running smoothly and 2) if there is a lot of dust and dirt on the CPU cooling fan and heat sink (and rest of the case for that matter).
Gently clean / vacuum the insides of the case AND power supply as best you can. Carefully vac the fan blades and heat sink to clear the dirt and dust that prevents the heat from being blown away by the fans.
When complete, you might even want to take the PC outside and reverse the vacuum so that air can be blown into tight places in the case. A can og compressed air can do the job instead, too.
It may be a virus or trogan problem. DO clear the Internet explorer cache and browsing history. remove all unwanted programs using add remove programs. please reply to me if u can solve with thos solutions
Is this on battery or power supply?
If on AC power supply, then it sounds like a heat related issue.
Make sure you can hear the cooling fan running and you may need to blowe the dust out of it with a can of compressed air.
