issue with audio device and USB ports

Recently I've opened up my laptop to dust off the CPU, in order to open up my sony vaio laptop, I had to remove my hard drive to take off the back piece. once I finished cleaning it and putting it back together, I had an issuse with my audio device and USB's. Its telling me it has been uninstalled. I've recovered my PC restored it as well. I intalled the missing drivers and still, I remain clueless. If anyone knows whats going on, and can give helpful ideas on how to resolve this problem. please let me know....
Thanks y'all
