I have a Dell Dimension 8400 PC desktop. When I tried to turn it on the fan will start and it will begin to boot but then suddenly stops and the light on the front goes from green to yellow. (Not blinking). I turn it off turn it back on and then it tries to go to last known good connection then turns off again. After a couple of tries I can get it to come on and it works fine. It does this about every other day. Any ideas?

Try going into Safemode. If the system stays on while in safemode, when try disabling start up items.
To go to safemode, press F8 when starting the PC or while you see the Dell logo.
To disable start up items, Click on Start>Run>then type MSCONFIG, then press "Go". IN System Configuration Window, click on Startup tab, then uncheck all the items. You can also use this link as guide.

If the system works find on safemode, or after removing startup items, then you have a software issue. OS reinstallation is easiest approach.
