Intel 925 duo core vista 32bit with 2GB ram. having lockups where the computer just stops responding while browsing, no HDD activity, the keyboard and mouse no longer responding, whatever is on the display remains, and clock stops indicating time advancing. Have given computer up to 30 minutes and it never came back without power boot. The lockups are not consistent, they occur sometimes after only a few minutes of operation to 10 hours later but always while browsing. I have disabled Secure Virtual Machine. I will know more after a few days of operation whether this is a fix.
