Later in the forum sticky you find about cleaning. But this one is very old so we need to go deeper to replace the heatsink compound. Along the way we get to assure ourselves that the heatsink is buttoned down proper and not wiggling or rocking.
The nice part about this is we are on a machine past its life span so we can learn more about PC and laptop repairs on such units.
This is something some techs think is optional. (heat sink compound.)
i did the reset that I saw on the forum and that worked, computer stayed on for about an hour then just turned off.
i cleaned the fan with an air gun prior to doing the reset.
the other day the screen had all kinds of lines on it and wouldnt go to the welcome screen, I turned it off and on a few times and finally got it to go to the welcome screen. today it wouldnt come on at all and then I did the reset and that worked, but as stated above it shut down after an hour.
what do you think is making it shut down? could it be the power supply, motherboard, not sure.
any suggestions would be helpful
