system wont start, no display

[hassanpk]

Hi guyz
I have a little problem here, or may be its big enough
I was trying to unlock my bios (lonovo pre-built) for controlling fan speed and some oc, as someone told me that you ca unlock it by moving some jumpers on the mobo, as I tried what he told me, the system gone black
Some beaps and no display
What I have done is this,
The jumper I moved, CLR_COSMO is written beneath it, it has 3 pins, the jumper was Initially at 2 left side pins and I moved it to 2 right side pins, after this I tried everything I know but nothing helps, so if you guyz have any suggestions then plz help me

 

[hassanpk]

Sorry
CLR_CMOSHW is written

That's the jumper to clear the CMOS. Did you move it back to the normal position?

 

[hassanpk]

Yes I move it back to its position, also ive checked by moving rams in diff slots, but nothing happens

Try to rum your system without jumper and RAM sticks your PC should make beeps

Yp, it makes the same beeps same as with jumper, and rams installed

So it doesn't start without jumper?

Thank you so much everyone, specially Mr. Ahmad, the guide you provided, I tried everything that mention there.
I took my system to the market and they charge me 4 dollars to reset my settings, now everything is fine. I dnt knw what did they do, but my system is running fine.
Can anyone has any idea what did they do to my system, so in future, if me or anyone else have the problem of this kind, then i may help him or myself.

I have no idea what they did but you could ask them about it, and I'm glad to see that your system runs for now
Probably they changed BIOS chip or made something with existing one!
