Ok so I hook up an IDE drive via a SATA card device and get it to work through the BIOS, I start noticing my keyboard seems to be laggy and intermittent, or sometimes unresponsive. I see the device is hooked up via the SATA interface in the BIOS and think little more of the keyboard. I transfer the contents of one drive to another, power down the computer, remove the temporary drive and start it up again. The keyboard is now unresponsive, but the mouse seems to still be working. The keyboard/mouse package is a Logitech Cordless Desktop MX3000, about 3 years old.

I plug in a different keyboard and mouse, joy so far, except for the mouse which occasionally zips to the screen border (any of the borders, top, bottom, etc.) Windows installs the drivers for the keyboard and mouse (if any were needed) and I restart the PC. The mouse still does a disappearing act on me occasionally.

The Logitech Cordless suite is a PS/2 mouse and USB keyboard plug arrangement, whereas the current arrangement I'm using is vice-versa.

There have been no driver updates for the MX3000 suite since late 2006 from what I can see. What could be causing these peripheral glitches? PS/2 & USB ports?

Suggestions and advice appreciated thanks.

It's CORDLESS!!

How can it possibly be a PS/2 + USB arrangement?

You should have a wireless keyboard and a wireless mouse, both 'talking' to a single USB antenna that sits happily on your desk.

It's not a sole USB antenna - it has a USB connector and a PS/2 connector (keyboard PS/2 connector is detachable), both of which must be plugged in for it to work. They have to talk to something right? How is it then that if the mouse talks to the wireless receiver, the keyboard cannot? I've switched over batteries and tried to connect but no joy. There's no unusual LED indicators on the keyboard, except when you try to connect it gives you the same green light as if it were to connect, but it doesn't.

I've never seen a wireless keyboard and mouse where the antenna had 2 plugs (that would appear to defeat the object).

I assume you have synchronized these units? The little rubber button on the bottom of the keyboard and the mouse, and the rubber button on the antenna?

Here is the user's manual for this product in PDF format. See step 3.

According to the instructions, you plug into either the USB or the PS2, but not both at the same time. If you use the PS2 connection, there is a purple USB to PS2 adapter for the USB portion of the cord which would connect the keyboard, the green portion of the cord would be for the mouse, both would be plugged in. If you use the USB connection (without the purple adapter), you leave the green PS2 cord unplugged.

And to be sure I re-synched them again. I did find the problem with this however, and the receiver was in a slightly skewed position from where it was normally. I had no idea that these units were so sensitive to position for reception, but when I put it back to it's normal position it decided to start talking to my keyboard again. Beats the hell outta me; I was starting to think about interference as a last resort, but I have no other devices that communicate at that frequency which also ruled out cross-talking and interference.

If I sit my mobile phone on the circular base that my monitor sits on, I get a warbling sound through my Logitech X-230s approx half to one second BEFORE my phone actually rings with an incoming call! There's a TWO second warning if I'm about to receive a text message! ;)

My Logitech cordless mouse and keyboard seems fairly unforgiving. I can use both of them from the other side of my room (of course from that distance you can't SEE the monitor) but I dare say as the system gets older, it'll begin to misbehave too.
