Hello ,Please please help I have just got a new computer and transferred my existing graphics card over to my new system and im having lots of problems. My system has a ASUS H81M-Plus motherboard and my graphics card is a palit jetstream gtx 760 2gb. Everytime i now try to play a game or run a graphics benchmark the whole system shuts down and has to be manually restarted.
Ive got all the up to date drivers and and a brand new 750w power supply.

Can anyone please help as the place i got it from say that it will take two weeks before they can fix it and it took me ages to save for this new system and i cant use it for anything besides browsing? please help.

I've just put a 750w in it so I'm thinking that my house and motherboard don't get along?
 
that could be but some how it sounds unlikely. is there a way you could check the Amperage that your wall outlet supplies? because if your wall outlet cannot supply 750 watts, then you PSU cannot supply 750. I am mentioning this as it has happened to me before.
