Computer Boot Problem

[ChrisMayhew]

Hello

I recently got a computer that used to be my sisters PC. She paid quite a bit of money for it and it's only been used id say about 6 times (One reason for me getting it)

However when i plugged it all in it wouldn't boot up, So i opened up the case and checked the connections inside. All seemed fine, However coming from the PSU when it has power going into it was a high pitched sound, and also the motherboard didn't have any power to the green light.

So i assumed this was a power supply problem. I remembered i had one still in box and tried that this morning, Now the motherboard light is lighting up but it still will not boot.

Could this be a motherboard problem?

None of the fans spin when you press the power button.

Any help would be awesome.

If the original PSU was dead, it may have taken the rest of the system with it.

Start with a barebones system: known good PSU (you may have fried your other one too), motherboard, CPU, RAM and video card (if any) connected. If this works, keep adding components. If this doesn't start replacing these minimum ones. Vid card and RAM are easier to swap, mobo and CPU a bit harder.
