Windows 7: task manager is showing only one core vs two

task manager is showing only one core vs two

I really hope someone has a good idea what is going on with my SSD partition of Windows 7 Professional X64 using a Core2Duo processor. I think I may have confused HAL with my old HDD that I currently have in my DVD/CD bay via an Ultrabay Adapter on my laptop.

I had the platter drive with Windows 7 installed first and then got the SSD later on. I installed Windows 7 on the SSD as a boot OS device. I shrunk the old Windows 7 partition on the platter drive and allocated a huge portion of what was left and created a partition for music, movies, etc.

That was my original idea. To use the SSD for fast boots and access and the platter drive for storage.

Now for some reason when I go to task manager I'll see only one core working under Performance. I also used Core Temp 64 it shows only one core also. I got a little curious and chose my old platter drive as the boot. That Windows 7 installation shows 2 cores working in task manager!

After reading some threads it seems that I may have to reinstall Windows 7 on my SSD. I'd probably think it would be wise to erase the old Windows 7 partition on the platter drive.

Any suggestions?

Hello Emerald,

Double check using the tutorial below to make sure that you have the Number of processors box unchecked in msconfig Boot tab.

Processors - Limit Number Used by Windows 7

Hope this helps,
Shawn

I've unchecked it and am going to reboot.

EDIT:

Thanks Shawn!!! It worked! Would you recommend deleting the platter installation of Windows 7? I only kept it in case something happens with my SSD.

Hello Shawn!
Thank you for this Tip ! It was spot on Somehow while meddling in msconfig I must have clicked near said option and of course the limit to 1 Cpu was set. I already restored to earlier Restore points to no avail. But thanks to you everything runs fine again.
