I have this comp and when i switch it on sometimes it does not come on and sometimes it gets to the login screen or before it and switches back off.
As soon as i try to switch it back on nothing no lights nothing
but as i try to keep switching it on and on sometimes the cpu fan does a couple of turn and off again but it sometime goes again until it gets to the login screen and off again.
I have looked at the fan on the PSU when it does start and that is working,i thought it might be something getting hot but i could leave the comp off all day come to start it and nothing at the 1st 2nd or 3rd attempt it just comes on when it feels like it aggrrrhhh.
any help would be great,i have ordered a new psu just waiting for it to come.
