BleepingComputer.com: Jerky Scrolling, No sound from speakers or headphones.

Okay, so my computer is a compaq hp professional. And It's a hand me down but we did get a reboot cd.
A week ago, my computer got a HUGE malware infection and I had to reboot the whole computer. So it's nice and clean now.

But the problem is when I'm on IE or FF, the scrolling is veryveryvery jerky and I took off the smooth scrolling so it would be faster. I even upgraded it. So I'm running on IE7 and FF 3.
Even making the windows smaller and moving them across the screen is jerky.
Help for that, please.

Another thing is that the speakers will not work. And I thought it was just the speakers at first so I tried headphones but that didn't work either. I tried going to the Start -> Accessories -> Volume Control because there was no speaker icon.
And I got this message;
There are no active mixer devices available. To install mixer devices, go to the Control Panel, click Printers and Other Hardware, and then click Add Hardware.

And so I followed the directions but I couldn't find that Printers and Other Hardware folder.
So I looked it up online and some suggested to go to the Sounds, Audios, etc folder and make sure it's on speaker. (or something like that)
But in the Audio tab, everything was grayed out.
Please help on that too.

After you reinstalled Windows, did you install video and sound drivers?
It sounds like you didn't. The video driver will get rid of the jerky scrolling.
Audio drivers will restore sound.

Do you have any other cd's for the computer other than the one you mentioned?
Your drivers may be on it.

If you don't have cd you will have to download the drivers from HP.
You can search for the drivers you need at HP support.
If you have any problems finding the correct drivers, please post back and let us know the make and model of your computer.

I have Compaq Presario SR1920NX Desktop PC, so it says on the site.

But I'm not sure which to download.
