Having problems with your HP Pavilion a706n PC Desktop ?

There is no power. The green lcd light is blinking on back. Other then that I can't get the machine to do anything. HELP!

Answers :

First thing to do is to verify that the pc isn't powering on.

- listen for the hard drive(s) and fans. If you don't hear them, skip these tips.

- open the cd/dvd drive bay. If it opens, you've got power.

Now, since this a vague subject, here's what the possibilities are IF the pc isn't power up:

- PSU (power supply) failure. They can be killed by power surges... frequent power outages from tripped home breakers, lightening strikes and so on. If the PSU fan isn't operating, it's a good sign that either the PSU fuse is dead or the PSU itself is.

- HDD (hard drive) failure. Although, in this case, you would get an error message on the screen informing you that no operating system was found.

- Improperly installed or loose componants. Sometimes the pc will simply shut down and refuse to start if RAM is installed incorrectly. It would also refuse to start up if the RAM were dead (not likely that all RAM would die at the same time though).

- CPU (processor) failure. Overheating caused by insufficient are flow (dead cpu fan or excessive dust) and power surges can cause a cpu to fry. This will cause the pc not to start up.

- Resource conflicts. If you've recently installed a new componant, the pc may not start if that componant conflicts with the resources that another major componant is using. In this case, uninstall the componant that you've installed and restart.

- MB (motherboard) failure. Excessive heat, shock or condensation can cause the micro curcuits of the board to melt, crack or short. In this case, there's nothing you can do but replace the board (tigerdirect.com can offer cheap, quality replacements).

Unless you'd care to elaborate further regarding the details of this malfunction, I'm afraid that you'll have to investigate each one of these possible causes to find the issue.
