I think that the mainboard in my desktop computer is starting to die. Yesterday, the PS/2 ports for the mouse and keyboard were causing problems and responding intermittently. Then all four USB ports stopped working. A couple of months ago, the onboard LAN stopped working for a few days as well. These problems were not limited to the operating system, either. The network problems were present in Windows and Linux, and one of my USB devices was unable to get any power from the ports. So, yeah, something is up. Fortunately, I have my Thinkpad to work on if this computer craps out completely (it is working again… for now).
Time for a mainboard upgrade… or maybe something a bit different?
