I am currenlty having the same problem. During normal operation the pc freezes, then after a time (sometimes short, sometimes long) it will resume working. If i open up the my computer link, my HDD for storage and software is not shown.( i am using an OCZ Agility 2 128G SSD for primary drive.) Try to restart the pc and it doesn't show the hdd in the list while detecting drives BEFORE windows loads, then freezes at the windows 7 spash screen for what feels like 5-10 minutes or more before it boots up and the hdd is still not in the hardware list. If i restart multiple times it eventually reappears in the list and works fine. Only changes i have made during the time frame that this has been happening is installing the beta for Rift. I removed/uninstalled Rift and made sure all drivers
are up to date. If i physically disconnect the drive the pc boots right up and runs with no problems at all. If i run the disk repair option during startup i get and error at the final step that says something along the lines of "System Integrity Error 0x490" reason listed is "patch is not working or failed". I can check the exact error description the next time it does this. Anyone else have a simular issue especially lately...i am thinking that something in a recent windows or driver
update may have caused the issue,
Thanks for any help in advance.
