Hi I've recently gotten a new PC build and I have a GeForce GTX 780. I have had issues with random freezes/hard hangs (probably PSU related - it's a Thermaltake 850w) but I am wondering if I should be concerned about my Graphics Card. I realise it will rev up/make a start up sound when it needs to 'power up' but I notice that sometimes (not just Battle.net but mainly) when I open Battle.net it revs up and while it is doing that my PC is unresponsive (say I click friends list in B.net and it revs up - I can't clsoe the friends list window or click anything for the 4 or 5 secs it is doing it). It seems weird but should I be worried? I have all the latest drivers (2.1.0.0) so I don't believe it is driver related (at least not recent drivers).
Any advice?
