Need to turn Computer off at wall so i can use front power button

Hi everyone,  I am writing this on my Compaq Evo, so it is functioning properly when on however, when I shut the machine down and go out for the day or leave it for more than 5 mins off, I go to press power button and the machine will not come on, then if I unplug machine wait 10 secs plug power back in, machine powers up no problem. Its only just started doing this and i'm worried it may get worse to the point where I cant turn my machine on, what do I need to replace if anything as I dont have alot of cash around to buy a new PC just at the moment

    To me it sounds like a power supply going bad.

Go to and look at some. All you have to know is the type (most are the same  ) And the wattage. You may get one with a larger wattage rating but not a smaller one. 
Select your D500 -??? manual for the weblink to the COMPAQ support website for your model below and download a manual to find out type of powers supply and wattage. They are easy to change . Just four mounting screws and replace one wire at a time so as nto to get mixed up.ℑ.x=9ℑ.y=3&lc=en&cc=us&dlc=en

It seems to be BIOS password, if you don't remember or don't have the BIOS password you have to reset the password by opening your CPU cover and removing the CMOS coin battery, this will reset the BIOS password but dont forget to return back the battery and start using your PC.

You need to have access to another external monitor to see if you can switch the video to operate the computer. Do you know for sure that the computer is booting up? If so, how do you know without a monitor? Also look on the keyboard and look at the function icons on the number keys, hold down Fn while holding down the key that looks like a monitor screen, this is the key combination that switches the video from internal to external.

Compaq Evo memory problem

Just thought I would update as I have just had the same problem.
I turned off the computer, disconnected the hard drive and processor and then reset the Cmos. Reconnected everything and started the machine up. Don't know what it did but everything works fine now.
Keep in mind you may not reset while power is connected to the computer, could damage the mobo.

No power (Compaq EVO D310DT)

The problem could be almost anything pertaining to the motherboard. The battery just helps the system keep time when it is powered off. One easy thing to test is memory. If you have spare memory ofthe EXACT SAME memory type for the computer, try putting it in and see if the computer boots. It could also be the power supply. If you have a spare one lying around then you could try replacing it. Other wise, you will need to replace the entire motherboard. If it comes down to replacing the motherboard, make sure that you get the exact same type as a replacement so that all your other components and peripherals will work.
