Hi,
I have recently had a monitor issue where my secondary monitor decided to stop displaying, therefore i tried to fix it... but i made it worse by somehow making it stop displaying my primary monitor too. So i looked for solutions online and found resetting my cmos might help (including the cmos jumper) but it made thing worse as well. Now my computer does not display or activate any usb devices (keyboard, mouse, etc.) and it starts the fans the HD the CPU and so on, but it does not do anything. I have tried removing my RAM and putting them in different slots and leaving some in, and leaving some out, and removing my graphics card. I have not found a solution yet which is why i have come here.

I have a M3N78 PRO asus Motherboard
I also have 4, 2gb RAM Sticks
A Antec 550 Watt Power Supply
And a XFX GeForce GTS 250 GS-250X-YDFV Video Card

What version of OS are you using? If it is a version of Windows, and you have a Windows installation disc for it, you could try booting with the disc and using the Startup Repair tools to try and get things going again. Or if it was a retail built PC, perhaps it has a System Recovery partition on it you could use to send things back to factory fresh.

without knowing knowledge about jumpers do not remove it!
Did you replace it back to the previous position?

Remove the RAM and start the pc and see whether the processor fan rotates and see whether you hear any beeps.

If you did not hear any beeps then there are 3 possibilities
1) RAM faulty
2) Motherboard faulty
3) RAM slot faulty
In your case you said

"Now my computer does not display or activate any usb devices (keyboard, mouse, etc.)"

From here i decide that your motherboard is faulty

But, from here,

it starts the fans the HD the CPU and so on,

May be your powersupply unit may be faulty

I did not come into consideration because yesterday i gone through this type of issue and still try to resolving the issue,

i have just recently bought the power supply only a month ago. is it possible that it could still be faulty only after a couples weeks of usage? You may be right unfortunately about the motherboard that's whats come to conclusion in every topic i see.
