Do you hear the fan running loud after shutting down Windows 7?
Do you have ASUS motherboard?
Your Windows 7 computers’ cooler or fan won’t stop after shutdown?
Here is what happened to me and what a user found out as the solution.
During the beta days I experienced a strange problem on my computer. When I shutdown, I still would hear the fan running loud. I didn’t know where it was coming from. I had Windows 7 beta on two computers and the problem occurred only on one computer. I think what I have done was opened up the computer and then shut down Windows 7. I think the fan that was running was the power supply fan.
This was a computer I assembled and had ASUS P5B-E motherboard. I posted an article on this blog about this problem. It turned out that a lot of people with ASUS motherboards had the same problem. There were posts at Microsoft and ASUS forums asking about the same problem. No one had a clear solution.
Then one day a reader on my blog posted a solution in the comments. It worked perfectly for my setup. Since then lot of people have been able to use the same solution to resolve their problem.
Since then I have changed motherboards on all my computers to Gigabyte. They are not known to be as advanced as ASUS. But I like them now for two reasons. First, they are cheaper. Doesn’t mean they are cheaper in quality. So far I haven’t had any problems or regrets about their quality. Second, all the ones I have purchased have dual BIOS. All my motherboards were bricked at some point by BIOS upgrades. A dual BIOS is very welcome feature for someone like me.
So, about the solution. A user named lemon75 (that’s all the information I have about this user) posted this comment with the solution in that post: Click “Startâ€, on “Computer†click right mouse button and select “Propertiesâ€, click “Device Managerâ€, select “IEEE 1394 Bus Host Controllers†group, only contains one device called “VIA 1394 OHCI Compilant Host COntroller†on that click right mouse button and select “Propertiesâ€, select “Power Management†tab, and finally check the “Allow the computer to tur off this device to save power†box!
Even today I am getting a fairly large number of hits on this page and people are searching for the same symptoms I and others were facing.
