check another power supply

Your computer is not POSTing, the best solution is to get warranty support on it.

The other option is to take it to a computer technician and he/she will diagnose the faulty component. They have access to many computer components and can determine the fault by a process of elimination.

go to download driver from hp site and here is the web site http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=pv-43507-1&lc=en&dlc=en&cc=ca&lang=en&os=228&product=1841849 and restart the computer .

The green blinking light can mean there is a problem with the power supply.

Try unplugging the computer from the wall, and turning on the pc on switch.

After a few minutes, try plugging it back in.

If that does not start things up, you may have a bad power supply.

If the power supply is bad, these models take standard power supplies. You should get an ATX 350Watt or higher power supply.

They are easy to replace, unplug the power from the wall, disconnect all the cables inside the computer. Unscrew the four phillips screws outside the back of the computer where the power supply is attached to the case.

Remove and replace.

If you don't feel comfortable with this, a good local computer shop can help you out.

The computer's power light may blink to indicate that there's a problem with the power from the AC adapter.
