Turning off a core MANUALLY

Jolanpiep · Sep 18, 2014

Hey guys,
I have a AMD Athlon II x3 460 with a secret 4th core. I tried to activate the 4th core but my computer just shuts down. This happened before and my stepfather was able to turn the 4th core of MANUALLY and start up the PC again. Sadly he won't hep me this time.
So, how do I manually turn the core off? I know it's possible but I can't find it anywhere on the internet. Ideas?

Remember that I can't turn my PC on, I need to do this by hardware.

If you can't power on, you're pretty much up the creek without a paddle. You need to get into BIOS to do anything.

you can try resetting the bios. Check the motherboard manual for the steps or pull the cmos battery and leave it out for a few minutes.

Reset the bios defaults using the cmos reset jumper on the motherboard. This should disable that 4th core, which is most likely defective and why it was sold as a 3 core cpu instead of a quad core.

Bignastyid, the 'cmos reset jumper ' how does that look?

Do you have the manul for the motherboard? If not whats the make and model of the motherboard? The manual should be available on the manufactures website.

Is something like this:

You need to se your motherboard manual to know how do you need to put that jumper.

I think I did it right (Read the manual)
Now lets try it!

Nuthin
Just the computer turning on, fan working but no image...
I used the CMOS thingy to reset BIOS, no result it seems.
Also I tried to let the battary out for a while, didn't work either :/

Should my screen adapter be in my Motherboard or Graphics card?

Jolanpiep :

Try 1 then the other and see which one works, reseting the bios make have changed the default graphics option.

No result, just black screen...

If you have not made a mistake in resetting the CMOS (which you may want to try again, carefully, making sure you follow the exact instructions), then this may apply to your CPU or motherboard ... https://www.youtube.com/watch?v=r0yXqU-w9U0

I tried it multiple times, I'm not giving up! NOT GIVING UP I SAY!

The resetting actually worked, it's alive again! Thanks everyone for your help!
