Yesterday morning, I woke up, fired up my PC, and tried to get into windows. I could not move the mouse, nor could I type anything.
Firstoff, I have an Elite Keyboard from Logitech. It's USB, but has a USB to PS2 connector for it. I also have a Logitech MX700 mouse. My mobo is the Asus A7N8X Deluxe Rev. 1.06 board. Running Win XP Pro.
I had them both going thru a Belkin 2-port KVM switch for the past month or two, no problems whatsoever.
So I unhook them, turn off my PC, and hook my keyboard and mouse into the proper PS2 ports on my motherboard. Fire the PC up. Nothing. They don't work at all.
I even put a normal, cheap PS2-Only Keyboard in and try to get into the BIOS from it. No-Go.
BUT - I can plug my USB keyboard and mouse into USB ports and they work fine, no issues!
I remember when i study computer mechanics, and som girls in that class took out the mobo and put it on a cotton chair, they turned it around, flipped it and looked from different angles ( you could accualy hear the sparkles between the cotton chair and the mobo ^^). The wierd thing is = only the ps2 ports was burned !
