Previous drivers properly uninstalled? Via catalyst install manager and then DDU before doing a clean install of the latest drivers?
superflower is very popular.I think you need to geT rid of that psu and get a well known branded psu before I start blaming your gpu mate.
Well it looks like it's NOT the PSU.. as it's still doing the crashing thing even with the Super Flower PSU..
Any more suggestions?
Yea I did see OP mentioned he got a new SuperFlower PSU, but nowhere did I find him mentioning what watts or model.I dunno about a 'lot' of people.
Have you had chance to try the card in another machine? As Devrij the vape king suggested!
I would generally do a clean windows installation just to make absolutely sure that its a hardware problem.
Are you using the latest drivers, have you tried different drivers?
Does this happen in all games or just specific games?
It is most likely however a dodgy card and the fastest way to check it out is by trying the card in another computer
Could it be caused by the Windows bug?

So you are using 780Wa G7 Power Extreme and what other have you tried ?
You cant be using a budget psu with a power hungry card like yours mate, you gotta get a decent psu (eg corsair 850w) in order to rule out the psu.
But having said all that I have done some googling and found out that lots of people are having this issue and your only option is to RMA the card in hope to get one which will work fine.

Kaku said:You could try underclocking the core/memory to see if you can get it actually stable in game, but I'd RMA it regardless.
Super Flower isn't a budget PSU. Blurb on card box says 750W is needed, which is what I'm using, if it needed more, I'm sure the box would say.

LOL SuperFlower Budget?
SuperFlower have fast become the number one PSU brand this year..

Yea the G7 brand if I'm not mistaken it is one of those cheap nasty generic PSU available in Maplin.You should have read the post before replying instead of skimming a couple of words
He wasn't calling the Superflower PSU budget he was calling the OP's original Power Extreme PSU budget, he just hit reply before reading the thread and finding out it's already been replaced by the Superflower.
