I have an athalon 900mhz with 60 gig hard drive 42 gig available. I have a freshly defraged system that runs fine until. I try to use shrink ver 32 and it locks the whole system up during encoding. i have to reboot to start all over again. I have stopped all other apps running and have ver 9 of the direct x. I will lock at different percentages during encoding, as it doesnt seem to matter where its at on disk or which disk im trying to backup. This happens do different disks at different times and its driving me crazy. I have uninstalled and reinstalled this version and others of the same but it still freezes whole system. I have gotten it to work but its only reliable in about 1 in 10 tries and it doesnt seem to matter what disk im trying to back up. If it locks up on this one today it might work on it tommorow?? Please any ideas would help. This has worked in past on this computer but its not reliable.
