Hi Ive just fixed a friends PC as it was starting up and then 1 second later stops (only CPU fan spin) so i tried resetting the CMOS which i doubted would work but it didn't take long and of course didn't work. So its the power supply. Then i sent away for a new PSU for them id used a number of times before (the brand not the actually power supply) and installed it and booted the first time fine but as i though it had lost the date and time. Now i didn't think much of it so i unplugged it and took it round and it did it again. So how can i stop it?. It just looses the date and time but they are no way computer literate and would implode if i mentioned using the BIOS so any thoughts?.
