Either the new power supply you purchased is not functioning correctly. But, assuming it is now that you are getting some form of power to your PC, it is very likely the motherboard. Whatever fried your old power supply (or it could have just been the power supply itself) most likely fried your motherboard in the process. Probably not the CPU since the MB can't even post.

The power supply in this monitor has probably failed, but since HP
doesn't stock spare parts for their monitors you will probably need to
replace the whole monitor. HP only does full unit replacements on their
LCD monitor range.
HP also doesn't provide any electronic schematics so getting it repaired will be difficult.

Hello, its the same thing. Almost everytime when I clean my desktop of dirt and the memory stick got moved. When I power up the unit and only the fan and led comes up.
My first suspect will always the memory. I will just make sure to clean the memory connector using pencil eraser method., reseat and power up again.
In your case I suggest to clean its connector to free it of dirt (varnish like coat on the memory connector). If it still freeze, check the memory if one is already failing.

It a issue with the power supply or the SMPS. Change the SMPS of same capacity and then it should work..............sodeep

Download the latest iTunes to your computer and reset the iPhone. Then re-sync it.
To reset iPhone, press and hold the Sleep/Wake button and the Home button at the same time for at least 10 seconds. During this time, a red "power off" slider may appear and the screen may go black, but do not release Sleep/Wake and Home buttons until the Apple logo appears.
If iPhone won't turn on, or the display freezes or doesn't respond
1. Remove Sim Card
2. Hold in 'Home' button and 'On/Off' button together until Apple logo appears
3. Replace Sim Card
4. Hold in 'Home' button and 'On/Off' button together until normal phone screen appears.
Also, Try this:
1.) Shut down the iPhone 3G.
2.) Start up iTunes
3.) Hold down HOME button on the iPhone 3G
4.) While keeping the HOME button depressed, plug in the Sync cable
5.) A message will pop up to ask if you want to reset.
6.) Just click YES and the reset process should start.
