I have a D945GCNL motherboard placed in my CPU with core2duo processor since 2008. Recently, my Iball smps stopped working so I got it replaced. After connecting smps, the windows showed a hardware failure on booting and after that I realised that my 4 usb ports have stopped working. Moreover, the system sound level has become very low and gives some noise at the output. However the keyboard which is connected above the ports is working fine. The sound problem was there before my old smps broke down. However the problem with the usb ports have come up after the new smps. Also, everything else works perfectly fine as it used to be earlier. I cant figure out the problem. I'm currently having a Windows 7 64bit OS on my desktop.

What we can recommend you is to test the system out of the chassis, minimal configuration. (Motherboard with embedded processor, power supply and 1 memory stick).
Remove the CMOS battery and leave the system without it for about an hour. Then put it back on and restart the system.
