Problem #2. Trying to fix problem #1 ended with a HD format, fresh install of XT, drivers, hardware, etc. No other software installed, then I went to Windows updates. Downloaded updates and the PC hung up installing the first update. All subsequent boots would freeze about a minute after a complete start.
Problem #3. Another HD format, fresh install XT & drivers, etc, then install all hardware and programs. Did not attempt to download any Windows updates. PC functioned normally for days. Problem #1 was gone. Until I attempted the Windows updates again. PC froze again on downloading of updates, then total freeze. Problem #1 returned.
Any ideas? Thanks!
