I have problem with the DEP. Every time, I access the web a message appears (after 10 min) that "Generic host protection......".After that I cannot access the web (address not found) and when I read any song, it is asked to install the audio driver audio driver. If I restart the computer the problem is solved and when I access the web again the same problem appears. I format my system but no use. Please sent me the correct remedy.

I have problem with the DEP.

I doubt it, your error fragment sounds like a general fault, but DEP can usually be turned off in the BIOS or in the Control Panel > System > Performance options for select programs.

...is asked to install the audio

Confirm the audio driver is correct for your audio hardware and that the installation package you used to install it is not corrupt. Beyond that confirm your hard drive does not have errors by scanning with the drive manufacturer's diagnostic, your memory hasn't developed a defect with a memory tester (Memtest86+ or Memtest86), and that your browser installation isn't damaged by reinstalling it. Poorly written adware or malware can also cause browser crashing as well as outdated plugins or ActiveX controls such as Flash or Shockwave. Does it crash on a particular site or after a set amount of time? You can also try booting into safe mode and letting the machine sit unused and see if it crashes all by itself. The error message should indicate additional information as to what code module was in use at the time of the crash or other hints to determine what software pieces to investigate further. Also see Wikipedia: DEP for more DEP info.
