standby problems

[thesob40]

Im not sure whats goin on here but when im at my computer the cpu temp runs around 29-31c but when i do a switch user to log off of windows my temps shoot up to around 40c. Ive ran tests on all my fan speeds from when im on my comptuer and when im logged off and the speeds seem to be stable. Im not really sure what is causing this problem so anyone that has/had the same problem can you please help me out please. thanks.

Unless it's crashing, increased temperatures aren't a big deal.

Are you actually logging off, or just doing the "switch users' thing in XP? If you "switch users", Windows actually keeps all the applications and stuff loaded and running for the first user.

Do the temperatures immediately jump up by 10 degrees, like by the time you're logged into the other account it's already at the high temperature? Or do they just quickly but progressively increase and stabilize at 40? If you switch back to the other user, do the temperatures stay the same?

It sounds like there may be something in Windows that's causing increased CPU usage when you use the fast user switching. If by some chance you're running programs under both usernames that are heavy CPU users, then you may simply be hammering the CPU, since you're logged in and running the program simultaneously under both accounts.

first...yes im using the switch users for XP and when i do that after about 3-5 mins the temps shoot up 10 degrees and when i log back on the temps go back down to 30. there are only two user accounts on my computer in which i only use one of them so hardly any type of programs are running. I cant figure this one out at all. If its not windows that it causing this do you think it could either be my cpu or mobo?

and ty for the reply.

The hardware isn't doing anything the operating system and applications don't tell it to do.

When you say you "log back on", do you mean you log out of the second account completely and then back into your main account? If so, then that would indicate that this second account is in fact running something that is causing very high CPU usage. If you completely log out of both accounts, not using the fast user switching, and then log in only to the second account, does the same thing happen?

If it ONLY happens if you use fast user switching so that you are logged in on both accounts, then it could be an issue with the way fast user switching is operating. When you switch users, all the first user's applications are all still running in the background, and Windows has to do some jiggerypokery to hide all that from the second user, and also run all the second user's programs. Unless you really can't stand to have to exit programs and log in with another account, doing a real logout is better.

see the thing is that i NEVER use the second account. like never...im only logged onto my main account and what i mean by log on is that i do the switch users thing then i go away from my computer...then when i come back i click on my account and type in the password and the temps drop back to normal...but during the hole time im away from my computer the cpu temp shoots up to 40 whcih isnt right.

Hmm. Okay you're using "switch users" to log out of the machine, but not actually log out. I assume that when you do this and log back in, all your applications are still open and in the same state as when you "switched" (i.e., an open Notepad window is still open with the same text as when you switched), which indicates that you are actually doing the fast user switching, not actually logging out.

I've never personally used the "switch users" option because I use the classic Windows interface and disable fast user switching.

Even if you don't actually log into the second account (which until now was not clear, when you say you "switch users" that sounds like you actually switched to another account), Windows is still calling up whatever APIs and DLLs and drivers it needs to handle the process of "hiding" your running programs and login so that the second user can log in. Just the fact that you've called forth that process may be resulting in the heat.

If you actually do switch users, and log into the second account, does the CPU remain at such high temperature? If the temperature goes down then it's something that is involved with the system sitting at the user selection screen that's causing it, this may be a bug/feature where the program that runs to give you the login screen just happens to cause high CPU usage. That's entirely possible, even just sitting at your BIOS setup screen causes high CPU temperatures sometimes.

If you don't need the feature of being able to instantly go back to the same state on your system, you can disable the fast user switching, which would make it so you actually log out of the machine, closing all of your programs when you do. It's in Control Panel, User Accounts, and select "change the way users log on and off". At the very least, you could disable it and test whether it makes any difference.

If you do need it, it's really nothing to be that worried about. 40C is not at all a high temperature, my 2.3GHz X2 runs at 40C at idle (granted it has two cores putting out heat).
