Hello!

I just bought an AMD Radeon HD 7770 (Diamond Multimedia) VGA, i've installed it in my computer, installed all the drivers and stuff, it's ok, but when i run a more demanding game, like Skyrim(on ultra), it starts, loads, and playes very smoothly and after like 2-5 seconds of playing it freeze, sometimes a message popup saying, "Display Driver has stopped working and then recovered"(or something like that) and all i have to do is to open Task Manager and close the game from there, and then everything is fine, with games that are less demanding it works fine. PS. the video card PCI-E's slot is 3.0 and i have a 2.0 slot on my motherboard, but i searched it and everyone sad that it's supposed to work just fine. Oh, and on the box it says that the card req. at least 450W(Power Supply) and i have 485W.

What should I do, change my Power Supply and/or Motherboard, try other Drivers?

Here are my specs:

Motherboard: ASUS M5A78LM

CPU: AMD SIX Core 6x3.9Ghz Turbo

4Gb DDR3-1600 Kingston(RAM)

Harddisk: Western Digital 500Gb SATA3

Video card: AMD Radeon HD 7770 1Gb GDDR5, PCI-E 3.0 (Diamond edition, Diamond Multimedia)

DVDRW

Sound: 7.1 HD Surround

Power Supply: 485Watts

Please help.

Thank you!

Yea, that's what you call a bog standard piece of *****, get a Corsair TX550. Quite possibly it is drooping to 11.8v or below under such a heavy load which isn't sufficient.

So what you are sayin' is that i need to get a better Power Supply?

Yeah.. the community here has a special kind of hate towards unbranded/low quality power supplies and with reason! There are very few companies out there who can make an efficient PSU and in 9/10 cases while having instability issues, crashes etc. switching to one of these solves the problem.

Thank you very much! I'll buy a new PSU and then reply if it works or not

Thank you again.

I've get the latest updates (12.11) and adjusted the overclock and now it works just fine, but i still think i need to get a better PSU.

But, what matters is that it works, everything is just fine  

Thank you very much for your time.
