Computer wont boot after "Core unlock"

post #1 of 11
Thread Starter 
So i was in my BIOS putting my FX-4100 clocks back down to stock because temps were getting a bit high.
Anyway my friend mike is here and wanted tot ake a looka t the BIOS so i let him didn't think he would break anything
but BAM he did. He enabled core unlock , hit F10 and then computer went off and wouldn't come back on.

proc: FX-4100
mobo: MSI 890GXM-G65

All i can think of doing is reseting the CMOS but i dont have an AM3 proc to flash the bios with.
So i will have to buy one.

So yeha i aswered the Question of "What to do?" by myself i think.
What i was really wondering is is this a normal thing? I know computers get BSOD or something when the core unlock fails
but i cant even get into the bios anymore. Nothing happens the PSU,board,fans, etc all boot but display nothing.

Resetting the CMOS shouldn't change the BIOS version (eliminating the need to re-flash the BIOS with another chip).

Oh it doesn't , Sorry I've never reset CMOS and when i read that it resets bios i though it meant back to original not just the version settings.

Nope. A BIOS flash is semi-permanent, as in you can revert back to an old BIOS with a re-flash). Just reset the CMOS and you should be good to go.

Never let a friend...screw with your BIOS. tongue.gif

It just doesn't turn on at all?  Seems like the kind of fault that happens when the VRMs fail (this board is known for it, but really only on the x6) but it doesn't make sense - all you did was enable a feature that wouldn't really do anything.
The FX-4100 isnt supposed to be an unlockable chip.


Try a reset CMOS.  But if it doesn't turn on at all (i.e. it might turn on and POST but if it doesn't turn on you may have a serious hardware issue) something else may have went awry.

My brother runs a Phenom x3, and the motherboard has a core unlocking feature built it. Trying to use it causes the system to turn on, but not post. No video image, but everything is on and running. That might be what the OP is experiencing.

Reseting the CMOS should do the trick.

Sounds more like a no-turn-on issue to me seeing from this.  What you described would be a "no POST".

i agree. try to reset the cmos with the reset cmos button and see if it resets it enough to make it work.
