Recently my power supply burned out and I had it replaced. Since that time I have paid close attention to the system's temperature through System Mechanic, a product that, among other things, monitors hard drive temperature. Every day, within an hour after I turn the computer on the temperature reaches a warning stage of 104 degrees F., and slowly rises to 112-114 degrees at which time I turn the computer off. Could you advise me on what to do. Thank you.

Clean all the dust out. Make sure all fans are running. Locate the computer in a place with good air circulation.
Whoever replaced the PSU probably disconnected some fans, and as tig mentioned it would not be a bad idea to blow out any dust at the same time. Run the PC with the case removed so you can see what is or isn't spinning.
