Can't play audio, or any kind of video, online or offline.

Something went badly wrong with my computer since yesterday. I was deleting files in my Local Disc C (I didn't touch anything on system32 or anything that sounded important BUT there must have been something that I have touched and I don't know what it is.) and the next day, I couldn't play a video I was supposed to be watching on the internet. I tried playing my movies on my computer and it still doesn't play. It seems to be kind of stuck since the unmoving shots of the movie is there. Same with YouTube videos. It just keeps buffering and buffering and showing an unmoving shot. I've tried doing a sfc \scannow but it didn't work. I don't know what to do. There's no start-up sound, it seems like something is disabled. Can someone please tell me what to do? It would be greatly appreciated.


I have tried downloading my Flash Player again which I stupidly deleted because I thought replacing it would do the thing. But it only made it worse. I could not download my Flash Player. Sucks. Also everytime I want to install Java it gets an error. I really need some help on this.

Did you try a System Restore to a date prior to the issue yet?

I couldn't. Everytime I tried to create a restore point it says the shadow copy is timed out.

How much free space on your C? What is your System Restore max % allocated? check in the configuration settings.

Can also check cmd(run as admin): vssadmin list shadowstorage

The following is a copy-paste from a previous thread. Go through only if system restore is at 50%.

To answer you, no it won't matter if you delete restore points or change the % back to whatever you want it. It will come back after a restart and fill that space again.
You can try:
- go to control panel-> programs and features -> Avast -> change
- remove the component NG (may also be called-Secure Virtual Machines or Sandbox).
- change % back to 10% (windows default) or whatever you like it
- restart
- check if % is what you set
- check restore points (seems this NG delete old restore points when run out of space)
- manually create a restore point if there are none
- open command prompt ->vssadmin list shadowstorage
- see how much space it takes.
You can also try uninstalling Grimefighter.
