I have a HP Pavilion that won't start up when I press the start button. It hasn't been used in a few months. It worked fine when last used. Nothing at all happens. Any help with this will be greatly appreciated!!

What model pavilion?

1. Make sure you power cord it plugged into the PC and your surge protector. If it is reseat it.
2. Make sure the surge protector is on. If it is, reset it, then try another surge protector.
3. Test the wall outlet to make sure it has power by using something like a desk lamp.
4. When you press the power button do you get any lights or hear anything? Does the Power Supply fan in the back spin and do you feel any air moving?
5. Check the power supply and see if it has a secondary power switch, make sure it is on.
6. If you are in the US check the power supply for a red switch and make sure it says 115 (your PSU may not have this).
7. Has anything been added or changed to the computer, hardware wise lately?

Open it up and check if any of the connections have fallen out of there socket. Check the power connections IDE cables, sata cables if any, and the power switch from the case is still connected. If you have another psu try that as well if you can.

I agree with warriorscot. My guess is a loose power connection. It's happened to me before. Unplug your computer from the wall (just in case). Open up your case and try pushing in all the cables connected to your motherboard to make sure they are not loose.

Or (hopefully not) it could be a dead power switch. If you are inclined, and know what you are doing, you can test this by unplugging the tiny cables to the power switch and replace them with the reset switch cables and then use the reset button to turn on your computer.
