I replaced a power supply that failed. Now, after shutting down the computer, I can not turn the computer back on unless I first unplug the main external power cord going into the power supply or turn the power supply off and then on with the power switch on the power supply. I have the following:
• Antec EarthWatts Green EA-380D Green 380W (new)
• ASUS K8N-E 754 NVIDIA nForce3 250Gb ATX AMD Motherboard
• Antec SLK2650-BQE case
I have cleared the CMOS and reset the BIOS. Same results.
Also, after turning the computer back on, the USB mouse is not recognized until I unplug it from the motherboard and plug it back in.
