I was cleaning out my computer's hard drive cuz it kept freezing and I figured I should get rid of everything I don't use. Well, as it turns out, I accidentally deleted my sound-system that came with my computer. As a result, I have no sound for anything. Can't listen to music, can't watch videos, etc. The system I had before was an "audio device on high definition audio bus", or, at least, that's what my computer tells me. If anyone has any advice on what I should do, that would be fantastic. Thanks for your time!

You need to remove the hard drive from your laptop and connect it to an USB hard drive adapter. You need access to a computer that has Internet access then download and instal the Recuva program.
Recuva (pronounced "recover") is a freeware Windows utility to restore files that have been accidentally deleted from your computer. This includes files emptied from the Recycle bin as well as images and other files that have been deleted by user error from digital camera memory cards or MP3 players. It will even bring back files that have been deleted from your iPod, or by bugs, crashes and viruses!
Put the memory card into an USB card reader and plug it into the USB port in your computer, then run the Recuva program.
Simple to use interface - just click 'Scan' and choose the files you want to recover
Easy to use filter for results based on file name/type
Simple Windows like interface with List and Tree view
Can be run from a USB thumb drive
Restores all types of files, office documents, images, video, music, email, anything.
Restores files from removable media (SmartMedia, Secure Digital, MemoryStick, Digital cameras, Floppy disks, Jazz Disks, Sony Memory Sticks, Compact Flash cards, Smart Media Cards, Secure Digital Cards, etc.)
Restores files from external ZIP drives, Firewire and USB Hard drives
If you aren't sure what you're doing, bring it to a service tech or you may render that external hard drive completely useless:
Before you start cleaning make sure you back everything up onto another disk. If you are giving your computer away check with the person or organization to see if they plan on cleaning your hard drive for you. However, the best thing to do is to clean it yourself.
Download a hard drive cleaning program or go to a computer store that sells computer software and buy the program. This is the safest way to make sure the hard drive is all wiped clean. Running the software program over writes all the data on your drive, making the hard drive impossible for anyone to read. The software works by over writing the drive many times.
Make sure you give yourself plenty of time in wiping your hard drive clean because if you have a lot of stuff it will take longer to clean.
Once your running your program and the box comes up to erase your hard drive don't forget that this process is irreversible. You will now type in the word format drive letter and hit confirm that you want to erase everything on your computer.
Installing a new external hard drive if you are not getting rid of your computer, is another option you have. You still go about erasing the old drive because you're getting rid of your hard drive. Install the new one.
If however you need to re-install windows with a normal windows disc, everything will be lost and you will need the drivers for your motherboard and other equipment.
If you are doing a factory restore/recovery then you will loose everything, but all your drivers and programs that where on your computer when new will be there.
Feel free to ask if anything is not clear, or you need more information
Download and install http://www.malwarebytes.org/. Is completely free application and is one of the best out right now. Install that application the reboot your computer in safemode. Run the scan in safemode. After the scan is complete it will most likely get rid of the virus. It is about 98% effect here at our IT-Shop
if you know how to slave your Hard Disk, try to slave it on other PC with the same windows OS you have. Then the file that you accidentally deleted to your Hard disk, OR you may clone all the System file in the Windows folder " C:\ WINDOWS ". in that way your OS will run back to it's normal process.
Your system is headed for the dreaded red ring w/ three red rings. My system started doing the same thing just before this happend. If you have a service plan with it i would suggest returning it and getting a new one.
I tried all the there little tricks as well deleted everything off my harddrive all that good stuff i think it made mine worse. Cuz after all that i turned it back on and bam three red lights and no picture or sound.
