you say "had windows xp on it. did you try to remove it or is it past tense because you can not access it?

I have two MPC computers and access to two more, all with the intermittent problem of not powering up when the power button is hit. The green power light is on, but no fan or disk drive.

The problem on all four of these computers is that the power cord/or power input to the computer is not connecting properly. And the solution for all four is to re-seat the power cord. Funky as it sounds, this solution has worked on all four for over a year now. These computers are seldom off, so the problem occurs infrequently, if at all.

Computer one will start if the power cord is disconnected from the computer and then connected up again. Computer two, solution is disconnect, and reconnect, making sure that the plug is fully, and I do mean fully, pushed in. The third respond to the plug just barely inserted. The four has a mind of its own and responds after several disconnects and connects.

All of these computers are between 3-5 years old. In all cases I did not have to work with the video card, power supply or bios battery.

Give it a try.

Besdies the great points that Richdave makes, I would also try this:"Certain changes in BIOS settings (such as chipset timing or latency, memory timing or latency, processor clock frequency, etc.) can cause a system to no longer boot.

If you are able to enter the BIOS Setup by pressing F2, reset the BIOS to factory defaults by pressing F9. Save and exit the BIOS Setup.

If you cannot enter the BIOS Setup, clear the CMOS:

Turn off all peripheral devices connected to the computer.

Disconnect the computer’s power cord from the AC power source (wall outlet or power adapter).

Remove the computer cover.

Locate the battery on the board (see figure below).

With a medium flat-bladed screwdriver, gently pry the battery free from its connector. Note the orientation of the “+” and “-” on the battery.

Wait one hour then replace the battery.

Replace the computer cover.

Plug the computer and all devices back in.

You may also need to perform a BIOS Recovery after clearing the CMOS." from here with more info about your motherboard. Let us know what works and what does not so we can continue to try to assist you.

Do you get any start up beeps? If so how many?

May be a video issue. Can you check/confirm the monitor is OK. Swap input, cable etc and advise.

THESE MANUALS may give you some assistance.

Be sure to post back your findings to allow follow up help if required.

Try removing and re-seating the RAM - manual suggest removing AGP VGA for better access to RAM so remove/reaeat the VGA as well.

Try different RAM if you can. Can you test your VGA in another machine?

さんによる

what is the AGP VGA and i do not have another machine to test it on and i do not have any other ram

さんによる

Sorry - AGP = Accelerated Graphics Port - card slot the VGA sits in, VGA = Video Graphics Adapter - Video card. pull out and reseat the video card and pull out/reseat the RAM. If you have more than 1 RAM module, try booting with 1 only, then try the other, then try each module in turn in each available RAM slot to see if we have a RAM module faulty or a slot faulty
