I have rpoblem

Hello,
Hello, m cee

First i'll tell you how the problem began. I was plugging in an extra hard drive into one of my CD drives slot and while doing so i had to remove my ram chips and my CPU heat sink and fan. In doing so i had problems with my CPU but i fixed them my main problem was when i plugged my ram chip back into the computer i let of a static discharge and fried one of my ram chips! Now all of the sudden after that i get absolutely no sound from my integrated sound chip. My brother who is really good with computers and a worker at a computer store at Compu-silv in Brockville Ontario told me it had to do with a driver or my bios. So i checked both and they were fine. I downloaded the newest driver for my Realtek chip (version A404) and nothing changed! My other problem is i have Xp and Vista on my computer and both OS'S sound stopped so i highly dought it's the driver. Anyways my computer knows the driver is installed and yes i made sure the fricken thing was properly plugged in because i ain't that stupid. I even checked windows Vista and showed that my audio device was putting out a signal. So my chip is working i'm just getting no sound from it. I have tried multiple speakers so it ain't the speakers. I f anyone can help please reply to my message.
