Another Windows 7 x64 freeze after the 1.0.508 update in Malwarebytes for Windows Support Forum Posted January 17, 2019 The occurrence of this problem is random or semi-random and all this reporting about what one was doing or not doing when it triggered is a waste of time. The multitude of different machine configurations seems to make no difference. The one thing that *IS* consistent is that it affects Windows 7 systems. That is where the focus should be. Have they made a careful source code review of the version that does not have the problem and the version that does have the problem? There must be some difference in the code that could be discovered. Flailing around trying to trigger the failure is going about it backwards in this instance. THIS MAY HELP: On the first machine I had a problem with it is an Intel motherboard with motherboard RAID 1 dual mirror drives. After a period of pain dealing with this recurrence I saw that when the problem happened a RAID notification popup appeared that the volume had gone offline. When the disk access is halted you get the symptoms of the failure of something not working and then clicking on other windows that will switch at first then eventually won't switch anymore. Eventually the cursor grinds to a halt. There is never anything in a disk log. The problem is that the disk access is being shut off and windows can no longer function. Find out why the disk is being disabled!!
