Long beep? I didn't catch your BIOS manufacturer, but I would go ahead and reseat all cards and peripherals, including checking power cable connections to the hdd/fdd etc. Installing the PSU meant all the power cables to hdd/fdd/etc. had to be removed/reconnected, and this operation could have very easily knocked your video card or network card loose. It may just be a simple matter of forgetting to re-connect your keyboard/mouse or something very obvious.
