I have just built a computer for a friend, and I'm having a big problem!
It keeps cutting out over and over again, or just refuses to even power on.
It sometimes boots to windows, and after a little while, it will just cut out.
Then it will not power on at all until I twitch the PSU off and leave it till excess power drains out.
Then sometimes it will try and boot up, but the CPU LED will be lit up red on the MoBo, and everything will spin away, but no picture on the Monitor at all, and it left, it will again, after a few mins, just cut out.
Its driving me insane!
Surely the PSU have enough juice to power it all.
That would be the first thing I would check if I had a spare PSU, but I dont :s
Can anyone help me... could it be something obvious or is the most probable cause the PSU?
