I had installed Windows 7 Home Premium x64 on my Toshiba laptop several months ago, and as soon as the operating system was installed, I was having heat problems. I figured maybe it was because I had not yet installed any drivers
, but even after doing so and making sure they were up to date, the problem persisted. I then installed Windows XP Pro x86 with it as a dual-boot, and discovered that the laptop ran perfectly fine, just as it had with Vista as well. Knowing that this amount of heat is not exceptionally "healthy" for a computer, I went back to my Windows Vista Ultimate x64 & Windows XP Pro x86 dual-boot. I eventually called Toshiba about the issue, and they asked if my BIOS was up to date, I told them which version I had, and they said that it was up to date. They advised to take it in and get it looked at, which I refuse to do because it works fine in XP or Vista.
The heat problem I have encountered goes like this. I boot my computer up, and it boots up fine, until it is in Windows 7. The fan will run at a very low speed during this time, and will not change. When I put my hand there, the air it is blowing is not that hot. After 5 minutes, the fan remains at the same speed, but the heat it blows out is increasingly warm. After 10 minutes, the air it blows is very very hot, and almost painful to hold my hand close to the vent, and within a few short minutes, the fan changes its speed for the first time since boot-up. The speed it kicks into is incredibly fast, the fan at this point blows faster than it had ever blown in Vista or XP (still to this day it is not comparable to speeds it has blown in XP or Vista). The heat is incredible. After about 30-60 mins, more or less, the computer shuts down immediately without warning. I am all out of ideas, and I would really like to have Windows 7 but I don't want a fried computer.
