Sorry, I'm new here, so I'm not really sure how to word this, so I'll try my best. I bought an HP p6310f, everything default(6Gb RAM,Motherboard,etc.), except the graphics card, which I replaced. The processor is an AMD Athlon II X4 630 Quad-Core 2.8 Ghz. When I first got the pc, (about 2 weeks ago) all 4 cores showed up in my task manager and msconfig (tskmngr showed 4 windows in performance) Now, it seems like my pc is using only 1 core, and the other cores/windows do not show up. Any clue on why this is so? I updated my BIOS, and still, nothing happened. Remember, I didn't install the cpu, it came with the pc. I

In Task Manager select View, CPU History and the option you wish to

what is your system OS ? Turbo mode enabled and the system is idling it may use minimum cores
Press Windows Key and R and Type Msconfig, Goto Boot.ini Tab and Then click advanced --- Set /NUMPROC= to the maximum , Ok and restart the system --- Open Task manager when back in windows

Windows 7 Service Pack 1. Tried msconfig before, only says 1, still no avail. I asked a buddy, and he said the other cores burned out, but that wouldn't be likely, right?

Hmm .. I don't know, dowload CPU-Z see how much core your CPU,
And Last option : try update bios from website your brand mobo, and backup important data, try Repair your OS or Recovery or clean install.

I've had cpu-z, still 1 core :/ . And I don't think I'll be able to reinstall windows 7, because I've used up thye disc alread, on 3 different pc's

On cpu-z I get the abnormal core reading according to your chart, and on this recording software, playclaw, it lets u use 1+ processor for recording, and it only gives me the option to use 1
