    Run these free diagnostics (try with only 2 cores and with all 4): Hardware Diagnostics
    Even with 2 cores - if everything passes, then you know it's the CPU.

    Windows 8


    well, memtest ran fine the other day when I did that test, and I am not able to find an other diagnosis from Samsung than "Samsung Magician - Benchmark Tester".
    I downloaded a Inten CPU tester, which yielded "pass".

    I was able to choose boot With two processors in Windows, and enable all four in BIOS - and this booted fine. Then I found all four cores under "Device management", but only two With HWInfo and another Software for cpu temp monitoring.

    I called the support phone for the shop where I got the Equipment, and they said it would most likely be bent pins. So I removed the CPU again, and double checked for bent pins - not finding anything but all pins at line.

    I Guess this looks like it is some hardware issues With motherboard or CPU?

    Maybe I forgot to mention that the system did not boot under ubuntu (from usb) either. The error Message there was:
    "BUG: unable to handle kernel"

    I Will proceed to return the hardware...

    I agree, return the hardware and start fresh.

Windows 8.1 uses more than 2 cores? in Performance & Maintenance
Back in 2008/9 I had the Intel Q6600 cpu and at that time games and OS barely could utilize more than 2 cores of a processor. How are things now? My straight forward question is whether windows 8.1 utilizes more than 2 cores? Does it make sense to upgrade to a quad core for a HTPC just for a fast...

I have an AMD FX-8120, it is an 8 core processor but Windows 8 seems to be only be recognizing 4 of them. Here is a screenshot from task manager 10408 It does say Physical Processors 8, but as far as I am aware it should also say it has 8 cores. Help would be greatly appreciated! Keir
