Hi guys, this is my first post in this forum and I hope someone can help me with my problem.
Here is the story:
I left the computer on last night and everything was working fine, when I woke up this morning the computer was running but non responsive. The monitor was off and neither the keyboard nor mouse was working.
I restared the computer, and tried to log in however the keyboard and mouse were still not working.
I got an old PS2 keyboard and connected it up to the computer, and then restarted the computer again. The PS2 keyboard worked perfectly (unfortunately I don’t have a PS2 mouse).
I entered BIOS to check that USB was still enabled which it was. So I logged into windows, the USB devices were still not working, however windows did come up with an installing new hardware prompt when I plugged in the keyboard (the keyboard remained powerless however). There was one exception however, when I plugged in my Ipod it worked without a hitch.
I then decided to get an old 10-1 pin USB connector to plug into my MOBO, and I used that instead of the MOBO USB slots. Again the slots worked with my IPOD but not my keyboard or mouse.
I then thought that maybe a virus or something downloaded onto my computer during the night, which would explain why it was non responsive when I saw the computer. I discovered that windows Service Pack 3 had been installed during the night.
I uninstalled service pack 3 and downloaded and installed service pack 2. However I could still not get the USB keyboard or mouse to work.
I have to come to the conclusion that when SP3 was installed it somehow disabled some of the USB capabilities. However I have no idea how to get it working again. There is obviously nothing wrong with the hardware, because my Ipod does work.
I have run out of ideas, and if anyone has any idea how to fix this issue I would greatly appreciate it.
Mike
