It appears as though you've got an operating system installed but you didn't tell us which one..?
At this point, it also seems like you need to update the chipset/motherboard driver for your machine and/or the BIOS.. If it's Intel, the chipset driver should be fairly easy to find and install.. And if it's not detecting the various CPU cores, it could also need the BIOS upgrade.
After the above steps are done, the computer should recognize any type of correctly installed keyboard..
Hope this helps.
I believe I have a mobo issue, but I'm not sure. My computer will start up, beep it's standard beep but in the first boot screen, it will get stuck at the point when it is recognizing the processor. I have an Intel Quad Core processor, but it only shows 1 CPU, whereas it used to count up to 4 CPU before continuing to Windows. I reset the CMOS but all that did was get me to the mobo initial screen at which point it asks me to hit delete or tab to proceed into a menu, neither of which works.
The other thing I thought of is that I'm using a wireless laser keyboard. Could it be that the computer will only register key strokes from a wired keyboard?
Any help is appreciated.
