Re: Power supply was shuting down after a while and now...
This may be a bad power supply or an overheating problem. be sure the cpu cooling fan is spinning and you don't get, possibly, a siren tone from the computer (usual warning of over heating) Make sure the heat sink cooling fins aren't clogged with dust and that the heat sink is attached to the CPU correctly. sometimes a clip breaks and the sink loses contact with the chip. if this happens, the chip will overheat almost immediately.

You want to reset your internet connection??? If yes then follow the given steps....
Turn the modem so that the back of it is facing you. Locate the power supply cord connected to the back of the device. Step 2
Gently unplug the power supply cord and leave it unplugged for about 10 seconds. If you also have a router connected to the modem, disconnect the power cord of the router as well. Step 3
After about 10 seconds reconnect the DSL modem power cord. Wait for the status lights on the front of the unit to come on. They may blink at first before turning solid green, or they may first illuminate as orange, then turn green, depending on the modem model. The "Internet" and "Incoming" lights may continue to flicker, this is normal operation for modems. Step 4
After the modem is reset, reconnect the router power supply if you have a router. Wait a few minutes before resuming normal Internet use.

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.
