Any Clues To This problem a friends computer is having, it's an old computer (about 8 years old) & running Windows XP.
I started it & it fired up okay first time, it took a while to load but when done it ran for about 5 minutes then off,
as if we had power cut.
Tried to restart but only get a couple of turns on the fans & that's it (had removed side panel to observe).
Had to turn off/on the mains plug to get it to again only rotate the fans again a couple of times. It did start once
again but did the same thing & shut down again within five minutes.
Also did Ram Modules Check + Blew Out internal Dust Build Up
