When power on - leds goes on & thats all

Specs: Windows 7, i7-2670qm / 2x4GB
I got a lenovo ideapad i570 (or maybe I had one..). Year ago while I was playing my USB restarts every once and awhile.. I saw at the event log that it was like "too much current draw" I spot my mouse was doing it. I shorten it's cable and all worked 100% since like a month ago. When I press the power button (on power adapter or battery only) the LEDs comes on but thats it.. No fans, No HDD, No anything. I get it apart and I spot a Vccp rail on ground on the motherboard. I am going to order another one but my question is.. Is there a way that my CPU/Ram can die too from this rail? I am curious if I change the motherboard with other is it gonna be running again.
I can not say for sure that it was the mouse.. I just think it was it because of this problem before. Do not think it was due overhearing. No beep or any other symphoms.. It just stop working and when I try to run it the described above is going on.

Nobody will be able to be quite sure. FWIW my inspired guess is that the RAM & CPU will have survived but I could be proved wrong if the short produced a big spike.

Always pop back and let us know the outcome - thanks

Well I'm hoping for the same. Yeasterday (9th) I order a motherboard (from big world-wide trading website, US seller that sent it like a hour later from Germany). In the description he said the shipping for EU (specially my country) is 5 working days. Hopefully next week I'll know if it was the mobo only or maybe I'll figure out something else. Quick question.. If let's say CPU is out and I put it, can I damage the motherboard that way? (same for ram, hdd, wifi adapter?)
Thanks for the quick replay, hope I'll have some good news soon :)

Sorry to be such a boring "don't know" but with sparks and arcs things are quite unpredictable. There are stacks of ways hardware can fail Again I feel positive from you original explanation so I sincerely hope I am justified. Let us know how it pans out.

Always pop back and let us know the outcome - thanks
