Ok, so I had a new mother board INSTALLED a month ago - shop gave me a disk for my reboot when it came TIME, so I went and wiped off windows and re-installed b/c there was a bunch of stuff going on with the computer, so after the install I now have no sound, and when I'm on IE the computer has a really hard time scrolling up and down, you can visually watch as it refreshes each line as it goes downt he screen. Videos play fine, (no sound) - so I dont know what to do. Any suggestions? I havent called the shop yet b/c I wanted to try to fix it myself. Any help is greatly appreciated. Thanks

click Start then Run and type in Devmgmt.msc and click OK
This will take you into DEVICE Manager. If you SEE a yellow "!" next to any of your devices then you need a driver for that device.
Your computer may have came with a drivers disk. It might say something like: Drivers and Utilities or something similar.
If you don't have a drivers disk then the best place to get them is from your computer manufacturers website. check that out and see if they have a driver download page.I found yellow errors with the "other devices" and it is the ones that control sound, communications and VIDEO. Any suggestions? I dont have the original reboot disk with the drivers, i have a new one that was made for me when my new mother board was put it, and he didnt put those drivers on the disk.Visit your MBoard manufacturers site and grab the MBoard drivers.
You didn't mention whose board it is or Links may have been posted.The guy that installed your motherboard should have run the drivers disk. He at least should have given it to you after the install. Is this guy claiming to be a professional?
Do you know the brand of motherboard you have now?He must have missed something on the disk he made me. Once I found the yellow ?'s I went in and had windows search for drivers to update it through da interwebs and it worked. I got sound, I got better video quality, and my interent is not slow as fawk. Thanks for the help guise. Good News...
But in future don't rely on Windows to update/install Device drivers.....always go to the manuf. site for the right ones/
