I rebuilt my computer &, after a few minor hardware hickups (nothing too serious), I installed 7 Pro 64Bit w/SP1 last week. During OS installation, this happened a few times:
The computer would freeze, just freeze w/o any warning messages/anything to let me know it was about to happen. This would happen when I was on the final portion of OS installation/after OS completed installation & while updates were on their last leg of installation. I had to restart the whole OS & updates installs each time, but now everything is finally installed.
The next day I tried to update my System Rating & the computer froze up. I rebooted & installed Avast! Internet Security; did another reboot (as Avast! asked) & tried to update my System Rating again ... computer froze.
In both instances though, it froze in different places: the 1st during either Direct3D Texture Load/Direct3D ALU & the 2nd during either CPU/Disk Performance. I tried again yesturday & again computer froze, this time during Windows Media Playback. I can't pin down the probelm, this is frustrating.
