I'll try to describe as much in detail as I can. We just recently purchased upgrades for our computer. An 8800 GS Corsair XM2 800mhz dual channel memory an Antec true power trio 550watt Gigabyte P35 it was the ds3l (I think) we have a P4 2.93 ghz currently overclocked to 3.8 (we are going to upgrade that too) we have a Jungle512 fan a dynex mouse a joystick made by logitech and we have a keyboard I don't know who it's made by and we have some speakers from logitech too. anyways when the PSU GPU MOBO and memory arrived we installed everything installed vista and installed the drivers for the motherboard and graphics card and I think those were the only two. Well the psu had a defective fan on it so we returned it 2 days later and got everything set back up and we went into windows logged in and it said "found new hardware" and it starts installing a driver. It won't let us stop the installation and it kills the mouse and keyboard we have tried practicly everything and it still isn't working.
