Ok, I want to start off by saying that I do have a dual core processor. About a year ago or so I bought a new, larger hard drive. After installing it I wanted to move everything over to new hard drive from my old one and use my old hard drive as extra storage if I needed to. I wanted Windows to boot from the new hard drive and have everything run off of it. With that in mind I used a cloning program to clone my old hard drive. That seemed to work fine for awhile and then something came up that resulted in me needing to do a system restore or recovery. I cannot remember which.
Anyhow, after doing so it seemed to have reverted back to having Windows run from the old hard drive. I figured in the end it wasn't worth the hassle so I just began moving files over to the new hard drive and installing programs onto it. Something I should have merely done from the get go. Anyhow, before the system restore I noticed in task manager that I could set affinity to one of the cores...afterwards I noticed that option had disappeared. At the time I read that the option might not be available. So I thought nothing of it.
That is until last night when something prompted me to check my computer out a bit. I found that in the performance tab of task manager, it was showing only one core. I have the option One Graph Per CPU enabled. In addition I used CPU-Z to check and it says I have 1 core and will not let me select between the processors. In addition Core Temp indicates I have just one core.
My motherboard and cpu are below:
I have attached my DxDiag. It appears my best solution would be to back up my data I value on my old hard drive, reformat it and reinstall Windows. I wanted to find out if anyone had any other suggestions or ideas first. Thanks again! I definitely have learned my lesson regarding cloning drives...I either shouldn't do it or definitely need to read a lot more about it.
