I have an Asus G72GX gaming laptop running Windows 7. It's never given me any form of insurmountable issue before, but this one has me at a complete loss. I got a blue screen this evening, on which it informed me it was unable to perform a dump of physical memory to disk, and have been unable to boot into Windows since. Some research has indicated that this appears to be Avast-related.
If I try to boot into Windows normally, it gets to the "Starting Windows" screen and hangs indefnitely. If I attempt Safe Mode, it hangs when attempting to load the aforementioned aswRvrt.sys. I cannot enter System Recovery or Startup Repair at all. The closest I get is getting a low-resolution Windows screen with a cursor, but a black background and nothing ever loads. No keyboard commands are accepted, even Ctrl-Esc or Ctrl-Alt-Del.
I used my wife's laptop to create a bootable Windows 7 recovery disk on a USB drive, and attempting to boot to safe mode with command prompt from there brings me to the black Windows screen, with a movable cursor, but nothing else functional. I have the program (whose name escapes me at present) used to diagnose such issues, but since I cannot access anything from within Windows (not even the command prompt), I am without any means of working on the problem. And if it matters, the DVD-ROM drive in the computer is non-functional... I have not had need of it in the past two years, so it has never seemed necessary to replace it.
Does anyone know of any way I can get past these issues? As it stands, I cannot even access the Asus partition to restore the laptop to factory defaults. Please help! Thanks very much for your time.
