Im having problems playing any game pretty much on my PC.
MOBO: Asus Striker II NSE
CPU: Intel Core2Quad Q9550 2.83.Ghz 12 Mb 1333F
GPU: XFX Nvidia GTX 280
OS: Vista Ultimate 64bit
RAM: Corsair (4x XMS3 1GB)
PSU: ToughPower 850w
This PC was built by a computing shop. It has currently been in for repair 4 times now, and all those 4 times it still hasn't been fixed.
They seem to tell me that 64bit software can sometimes be incompatible with many games, but if i am correct aren't most games such as Crysis, Left 4 Dead, Half life, WOW, Bioshock, Spore, BF 2, BF2142 run on 64bit!
My issue is that the PC Freezes/Hangs up and has sound repeating anytime i play games.
Ive started to notice it mainly does the hang ups when Anti Aliasing is enabled (and when it is, it crashes within 5-10mins).
(they also did an RMA on my graphic card)
Ive researched for nearly a year now and still no luck!
I read about in another forum here, that it could possibly be my RAM which is 4 x 1GB sticks. Could that maybe be the problem.
I'm pretty sure that the problem you have is the infamous nforce freeze. The BIOS settings look to be a bit different between the boards (you have a LOT more voltage options, and I don't know if the BIOS highlights out of range/dangerous voltages like the 790i does...), but the general steps would be the same: Sync RAM-FSB, and extra Voltage.
I have a very similar problem with lockups on a very similar configuration. I tried new video cards, new CPUs, new drivers, etc., but still had lockups during gaming with shuddering audio. After reading the posts on this forum, I increased my NB voltage from 1.33V (auto setting) to 1.40V (manual setting) and that seems to have fixed the issue. I'm also syncing 1:1 the FSB with my memory manually. I was already doing this via the auto settings, but I changed to manual just to make 100% sure they were in sync.
It seems like the 790i ultra chipset just needs a little more juice.
Thanks to gamerk316 and liquidignition for driving this discussion and fixing my lockups. I was about to go through the Asus warranty exchange process.
