Hi all, I've got a big problem with my new Dell Dimension 9200, and Vista ultimate 32-bit. Every few minutes the system hangs - the screen freezes, no mouse input, no keyboard input, and then about 30 seconds later it picks up where it left off. As you can imagine this isn't the most satisfactory way to get stuff done.. Each time it happens there's a logged error as below: Level Date and Time Source Event ID Task Category Error 01/04/2007 18:22:48 iaStor 9 None The device, \Device\Ide\iaStor0, did not respond within the timeout period. I've downloaded the latest RAID Controller drivers from intel (v 188.8.131.522) and installed them but it keeps occuring. Any hints?
