Anyone who are an expert in supporting PC can give me an opinion?
All in a sudden, it takes a long time for the mouse to activate after a reboot. Then after using the computer for several mins, mouse and keyboard freezed. Cold turned off the computer and turn it back on, it gave a long beep right after pressing the button, and shut down, then automatically turn back up again. Then it gave a long beep and shut down again. So it keep doing it forever until you shut down the power.
After repeating it hundred times, not it's back on, but still took longer for the mouse to activate.
I suspect the mother board. Anyone know what wrong?
