reboot a few times and make sure that the cables are in the correct holes.

Are they USB or PS2 connections?

Just a thought if they are PS2, during the cable tidy up you haven't swapped them into the wrong connector have you?

They are ps2 but when I boot the Pc if I've turnt it off by the power I'll press enter on the keyboard to "Start windows normally" and when it gets to the password screen keyboard and mouse don't work

The mouse works up until the music of windows comes up, any other suggestions I've rebooted it multiple times now

Ok just tried my old usb wireless keyboard and mouse and it works fine. Could it be the ps2 slots or the keyboard and mouse are fked (mouse/keyboard brand new)

Have you looked in Device Manager to see which Keyboard/mouse is selected? You could also try deleting what is there and allow Windows to find them again.

If neither device is working here is what I would do. Borrow a USB mouse, unplug the PS2 mouse but leave the keyboard in. Boot to Windows. Use the USB mouse to get to Device Manager, scroll down to the keyboard, right click and delete it. Reboot and let Windows find it agaain and see if the keyboard now works. If it does then switch off, unplug the USB mouse, plug in the PS2 mouse, boot into Windows and type devmgmt.msc into the Run box to open Device Manager, scroll down using the keyboard and delete the PS2 mouse, reboot and see if the mouse now works.

I type too slowly, if you have a working USB setup then it is easy to delete each of the PS2 ones one at time and let Windows rebuild them. PS2 ports are not hot swappable so if you have plugged or unplugged them while the machine is booted up you could have damaged the ports.

Could it have something to do with the mouse n keyboard not being compatible with windows 7?
