Windows 7 - Video & Audio problems, help?

Hey,

I woke up this morning and found my computer in power save mode, nothing unusual so I turned it back on and let it boot normally, however after logging in I found that my audio was gone (Speakers are working fine, plugged in and turned on) but the drivers are good and it is picking up on my driver and so on... But my video's are now choppy as well, I don't really understand the problem here and I have only recently got this computer so I am not really sure of its build and for the past 2 weeks it hasn't had any problems at all so I don't know what caused this problem.

Any information on this matter would be a huge help.

Thanks in advance.

did you already test at safe mode??

Yes, i've already tried Safe mode, Virus Checking, Problem Detection, Disc Cleaning, everything... All to no avail.

edit: I also tried reinstalling my audio driver which didn't help any.

try to /SFC SCANNOW and see what is you get.

Assume I am completely technology retarded, where would I run this?

sorry for the less information.. open command prompt and type that.

It just keeps telling me that /SFC SCANNOW is neither a internal or external command. Any idea's?

SFC /SCANNOW Command - System File Checker

This may take a while to complete.

Let me just add another thanks for giving me a hand with this, I was totally lost.

ok, post your result when finish..
