Computer will not boot

[karl01]

Yesterday changed my front two fans on my antec 300 case a simple job took old ones out and new ones in now when i turm on my computer i get to the splash screen the one where it says Asus p5q and the opitions to go into bios etc. Now it will not load past the splash screen unless i unplug my mouse and keyboard then it will allow me to load into windows any suggestions to fix this fault?

Alll cables are in checked and double checked the only way it will now let me boot into windows is when i take out the mouse and keyboard its so weird any one else had this problem before?

yes the mouse and keyboard work after windows loads up i plug them back in.

a straight swap in the same power connectors just went from blue leds to red leds.
