PLEASE READ TO END BEFORE TRYING!!!
Did you try the simple fix? First thing is to unplug the computer and then push the power button. Plug the computer back in and then hit the power button again. Did it start? Hopefully. If not and its a desktop, take the side cover off and look at the mainboard. Are the capacitors all flat on top? If any of the capacitors are bulging on top your mainboard is probably going to need to be replace. If not, pull the power connector off of the mainboard. Now take a technicians secret tool (paper clip) and bend it around in a loop and connect the green and one black wire from that connector. This will automatically turn the power supply on if its not defective. This is the simplest of tests for the power supply and will not tell you if you are getting the correct voltages but it will at least let you know if it works at all. Sometimes the fan will come on but the fan will turn slower than usual. This indicates a bad power supply as well. If the power supply is not the problem, plug the power supply back in and unplug all the drives from the mainboard. Now try to power up the computer. If it still doesnt start, remove your RAM and try to power up. If that doesnt work remove all the plug in cards. Try to power up again. If that doesnt work then its probably the Mainboard or CPU.

Hope this helps. If it does please rate it. Thanks...

My netbook won't turn on at all


Computer does not boot up
The problem maybe the RAM, it could be faulty or just needs reseating to make proper electrical contact.
Reseat the RAM and then boot up your laptop. If it still does not boot up then remove the RAM module/s and take them to your friendly computer repair shop and get them to test the RAM for you.
Just like you sometimes need a mechanic to repair your car, sometimes you do need a technician to diagnose and identify the fault or faults on your computer. Not only does a good service technican have the experience to deal with this type of problem, they also have the equipment that allows them to look at things the average computer user can't see, and he has a collection of replacement parts that can be used to quickly test individual components on your computer.

Won't boot screen black


A black screen on startup can be so many things! I have learned this lesson the hard way. Never turn off the computer when it is half way through the boot procedure. Even when it is taking forever, or having a major problem you must let it run through if possible. Interrupting it once may be ok, but twice or three times is a no no. After you have carelessly restarted and shutdown a few times the black screen may appear. But this time it may be beyond repair for the average computer user. http://tips4pc.com/articles/computer%20troubleshooting/how_to_repair_a_damaged_boot_sec.htm

Good Luck!!!!!!

Won't boot from dvd or hard drive, changed hard drives and still won't boot


Depends on what you mean by won't boot from DVD or Hard Drive,
it sounds like your boot order is what you're looking for help for.

To do this you need to get into your computers BIOS (or "Setup")
You can do this by rebooting the computer and the very very very first screen you see tells you how,
usually by pressing DEL or F2 or F10.

Without knowing the specific computer you're looking for help on I can only point you in the right direction however keep in mind the BIOS is for advanced users only and you can damage your computer by randomly changing settings.

What you're looking for though is usually called the Boot Order or Boot Sequence
You'll need to set whatever device you want to boot from higher on the list (usually with the up arrow or PgUp)
If you don't see your device on the boot list then it may not be detected due to failure.
