Several minutes after booting up, and usually when opening Windows Explorer, the desktop icons all disappear, along with the taskbar. Cannot launch TaskManager most times, and even when I can attempt to relaunch a new Explorer process, nothing happens. I can immediately invoke the problem by trying to run any command via the Run command line. SFC, Regedit, Msconfig, CMD, and even our own DDS.SCR, all cause the DOS window to briefly launch and then collapse. The only recourse at this point is to hold down the power switch until the laptop shuts down. Replacing C:\Windows\explorer.exe and C:\Windows|System32\cmd.exe with a copy from a clean PC did not fix the problem. I have installed and run the following:
ZoneAlarm Free Firewall
I have tried to run SDFix in Safe Mode, using all of the "possible problems running SDFix" solutions. The Best I can get even in Safe Mode is for the screen to go blank and be returned to the dialogue box that informs me I am "...running in Safe Mode, Click Yes to continue..." Removed and replaced ComSpec variable.
Still can't run DDS.scr - prompt window opens and close immediately.
The best I can offer for now is a HijackThis log - attached.
I thought I knew enough to figure this out, but I am over my head. Please help!
