Dual core cpu, only 1 showing up/working

[Matt]

While researching on my cpu I found out that it is a dual core, I checked msconfig, cpu-z and taskmanager and I only see one graph and the "one graph per cpu" is greyed out
msconfig and cpu-z also shows 1 core active
any solution for this?




No I dont have a messy desktop, it looks good to me

You might be able to fix this by reinstalling the latest Intel chipset drivers and restarting your machine. Good starting point anyway!

[Matt]

how can i do that? :P

Is your PC custom build, or manufacturer (OEM) built?

If it's custom built - you'll need the make and model of the motherboard.
If it's OEM built - you'll need the make and model (+ exact spec to search) of the PC.

Then you'll have to search the manufacturer's site for the chipset drivers. (Manufacturer will be either motherboard manufacturer, or OEM manufacturer of the PC).

my motherboard is BIOSTAR H61MGV3 7.0

TL;DR:

Download this driver and install it: http://download.biostar.com.tw/upload/Driver/Chipset/Intel/Infinst/Sandybridge/infinst.exe


No guarantees with this I'm afraid, but it's worth a shot!

Have you upgraded your CPU since the PC operating system (Windows 7) was installed?

It seems there is a tool and commands you can type in to fix this.

Stolen from the computing.net forum:

How to update from a single core APIC compatible CPU to a multi-core APIC compatible CPU

Under the computer entry in the device manager, you will see it says ACPI Uniprocessor PC, to update to the multiprocessor HAL input this:

devcon sethwid @ROOT\ACPI_HAL\0000 := +acpiapic_mp !acpiapic_up
devcon update c:\windows\inf\hal.inf acpiapic_mp.

Then reboot twice again to update the device and IRQ tables.

If the chipset update doesn't work (already mentioned in a previous post), then I'd try doing the above, or alternatively reinstall Windows as this will automatically detect the new processor!

Sh*t
I put 0mb of ram in msconfig by accident and after the windows boot logo I get bsod





RIP wooden pc  2007-2016, cause of death,dumbness

We've all done stuff like that 

As the PC is booting up, keep tapping F8, and you should get to an "Advanced Boot Options" menu.
Use the arrows to select "Last known good configuration," and then click enter to select it. I believe that should fix the issue <3.

[Matt]

  about that... I never put a last good config 

[Julio.]

That's okay  It should have automatically saved the last good configuration from your last successful boot.

10th bsod now
