I have a Dual-Core AMD Athlon II X2 250 processor.

Sometimes, when I press Ctrl+Alt+Delete it shows me only one diagram of only one core.

Usually it's two diagrams, since I try to catch the boot when it's two; but only one diagram bootups happen time-to-time.

Is it called hibernating? It's good or it's bad? ... Or it's just a hardware failure?

Also: My BIOS parameters regarding USB keyboard and mouse are turned off (unsupported) by default; how to reset BIOS?

Regards,
rhino

Hi,

There are 2 ways you can reset your bios.

1. On the motherboard there is a small watch battery. Remove this battery along with the power cable from the power supply. Hold down the power button to fully discharge the system. Wait 2-3 minutes then reinstall the battery and plug in your system. Your reset is now complete

2. Some motherboards have a 3 pin jumper by the battery. Lets say that the jumper is on pins 2 and 3. Remove the jumper while the machine is OFF and place onto pins 1 and 2. Power on your machine for a minute. (Note: Your system will not POST). Shutdown your machine and put the jumper back to pins 2 and 3. Your reset is now complete


You should use google more...

Hope this help,
Max

Many thanks Max, but that's not the main theme of this topic; I need to know why my Dual-Core CPU turns Single-Core time-to-time... I'll take your advice on resetting BIOS.

rhino

That's normal, IME...try double-clicking the single window appearing for CPU usage. You should then see both processors :).

One other thought. If you have AMD`s Cool`n`Quiet installed.

Well, I have "AMD Processor Driver" installed. Does it contains what you're talking about?

When task manager is open, go to performance tab, click on "view" then mouse over "CPU history" and select "One Graph Per CPU"

If Cool"n"Quiet is not listed in Add\Remove then it is`t installed.

Have you done as others have suggested regarding Task Manager to be sure it is set to show all cores?

When this problem occures there's only one grayed out option (unselectable), probably for only one graph.

Search your event viewer and see if you see getting any HAL errors posted.

Check this hotfix and see if it applies to your setup:
