Per my post #75 above, you know that I disconnected my two XP drives and disabled the TV tuner card from within Device Manager. The Win 7 drive was working alone without a freeze for many hours, when I got the idea that I should reconnect the XP drives for the sole purpose of doing a major copy of my sensitive data from the two drives to the Win 7 drive. I am planning on keeping the Win 7 drive as my boot drive, if it proves to be without fault. Before I reconnected the drives, I shut down, took a soft bristle brush and brushed inside each SATA data cable and power cable. I also brushed across the contacts on the sockets of the two drives. I rebooted. Everything was working as before. I did the data copying without a hitch....or a freeze. The three drives were purring along. Rather than disconnect the drives again, I left them connected just to see if my removal and return of the connections to the drives would have any impact on the freezes. From 2PM yesterday afternoon until 3AM this morning, I didn't have a freeze. The 3AM freeze was preceded by an action I took, that may have brought it about.
In my CMOS setup, there is a feature where I can enable or disable the speed control of the case fans that have a cable connecting them to the MB. The default setting is disabled. I enabled it and chose the Turbo speed for maximum cooling. I rebooted. Shortly after this, I had a basic freeze, meaning that the hard drives and fans DID NOT spin down and the CMOS settings WERE NOT lost. I restarted with the case button and disabled the fan speed control feature in CMOS setup.
Going back in time with the fan control issue, probably a year after the pc was built I was messing with a few ASUS MB provided installed programs that tweak the RPMs of the fans in the case. At the times I did this, I was unable to complete the next restart, with a halt to the process showing a momentary white on blue screen flashing a hardware failure message and many strange error codes. I had to grab the screen with the Pause key on the keyboard to see this. My pc was inoperable, even after several restarts and shut downs. Once I made a change to the fan controls feature in setup, which I can't remember, the pc booted to desktop as usual. Being a risk taker, I once again messed with the ASUS programs months later, with the same result and the same solution. Anything I did with the ASUS programs was by the book, and there was no warning about repercussions as a result of choosing any setting. Naturally, I'm thinking the fan control must be disabled in CMOS, based on the above scenarios, and the pc will misbehave if it is enabled. As of now, there hasn't been a freeze.
Hey, for all those believing that my MB is failing, above is a tease. You should also consider how the CMOS setting has allowed me some peace and quiet. Can I get some feedback on the contents of this post and that of post #75? It's been a ghost town around here since my last post, yesterday at 11:11AM....
