My computer is dumb.

***Something along these lines pops up when I turn on my computer everyday:***

(Sonic Update Manager CD Prompt When the Computer Starts
When starting the computer, the following message appears in a Sonic Update Manager window)

The feature...

you are trying to use is on a CD-ROM or other removable disk that is not available.
Insert the 'Sonic Update Manager disk and click OK.
This issue may be caused by program entries that are related to the Sonic Update Manager program.

HOW DO I FIX THIS? Usually I just click cancel or the little red X. But then everytime I try to play a game it lets me for about 15-20 minutes and then tells me I have 1 minute to save my work and then it (the computer) will shut down. Please help me.

Do this:
Go to Start click Run type msconfig go to Startup.

Look through the list for something like sgtray.exe, click the box next to it if and when you find it and click Ok, restart and see if that works.

Okay, I did that all except the:

avgtray
qttask
ISUSPM
rtuifrke
ctfmon

those are the only checked boxes and there is no sgtray.exe. ? I don't know.

Hrm, that's very little, everything there is normal. Except there should be a lot more than that...

If it where coming up when your comp started it would be in that list, is it when you do something specific?

Well I just turn on the computer and thats there, then I just X out of it to get it off the screen. Then when I'm the internet it doesn't do anything but if I play a game (specifically The Sims2) I will play for about 15 minutes and next thing I know, the computer is telling me I have 1 minute to save my work, and when that time is up it will shut down itself and restart up.

Sorry to say this, but try googling it, I don't know exactly what happens or I'd do it for you and find the solution.

That's okay, thank you for attempting :]
