I have an odd problem and google isn't helping. My computer was working fine yesterday no problems. This morning when I powered it on aero, audio, and internet all disabled. The audio and network adapter drivers are showing up fine in device manager. Tried to boot into safe mode and it hangs on aswRvrt.sys. I boot back to normal mode and clean boot. No change. I run chkdsk and it says the drive is clean, doesn't even attempt to scan it. I am not really sure what is going on. Any help would be appreciated.
