My HP Pavilion T3345.UK PC has been playing up of late! I turn it on and all the fans run overtime and the light on one of the CD drives comes on and stays on and that's it. Nothing else happens. I have had the cover off and have vacuumed all the dust out and cleaned the fans etc. The hard drive does spin as when I turn the computer off I can hear it stop. After many "on and offs" the computer will eventually boot up.
I'm thinking it might be something wrong with the PSU as when the problem first happened I gave the fan a good vac and spin at the back of the PC and the problem went away for a few weeks. Now its back but boots up ocassionally (like this morning after I fiddled with then fan on the PSU - with the power off!).
Does anyone have any other ideas before I try swapping (or getting a man to swap) the PSU?
