Anyone able to help me out on a little problem a mate has asked me about with his computer.
He is not too sure about RAM and thinks he's got the right type but may be wrong. He doesnt live here and isnt too googd at telling whats what so I havent been able to see anything as yet.

What he did was he wanted to update his ram so he put in a new stick to upgrade it. I assume for the moment it is the right type.
However maybe he has not got the right speed ram, not sure on that info as yet.
He added it and it slotted in fine.

Next thing, he goes and boots up and the system doesnt do anything.
So he sticks his old ram stick back in and boots up again.

Impossible to get back to where he was. All he gets is a message saying "Off mode" or something like that which comes up on screen.

I've never heard of something known as "off mode".

I've suggested he may have dislodged a component or car din the case and to check connections, or that he has incompatible RAM, however I dont know why once he has his normal RAM back in, he is stopped on boot and cant get further than a message saying "off mode".

Anyone able to shed some light.

Thanks.
