Hey guys,
I've been having problems with my current gpu-psu setup (at least that's what I've been lead to believe). I have an ATI HD5770 graphics card and PC-550AUBA-M psu. The problem is a recurring one in which the pc turns off (not 'no power' off - display goes black, doesn't respond to anything). I've been advised to replace one of, if not both, of these pieces of hardware.
Basically I'd appreciate help in choosing what I need to buy. I wouldn't trust myself to build a good pc to save my cats life. If I replace my current gpu with something more powerful do I need to do the same with my psu? Or could I potentially still use my gpu if I got a more powerful psu? I'm unaware of how this stuff works.
Erm, thanks for taking a glance, I'll happily answer any questions, I realise my descriptions can be both rambling and lacking in information.
Cheers!
