hi all, new to evga forum and a new owner of a GTX770 SC dual.
 
The problem I have is that every time I try to play a game, soon as game loads pc craches straight away.
I have uninstalled drivers and reinstalled as clean, seen another thread about doing that, but still same.

M/B ASUS   P7P55D LE
i5 CPU 760 @ 2.80GHz
zalman flower 9700
16gb ddr3 1600mhz corsair vengeance CL9
psu thermaltake 750w toughpower
C drive OCZ agility3 120gb
samsung 1tb
3 x LG 16.10 22in monitors
ReadyNAS
logitech key and mouse
 
 
 
 
 

thank you so much _Nite_
the newest driver i got from evga site is now replaced
I have installed the drivers that card shipped with .
that is 331.65 and hey and a game has played.
 
 

How is the pc crashing? Hard shutdown? Crash to desktop? Video driver error?

PoolKing
hard shut down. mid game and pc shuts down then re starts

Sounds like a PSU issue. Do you have a digital multimeter?

PoolKing
i don't,
but if nessesary i will find one

It's necessary. You need to test your PSU...
 
PSU Testing: http://forums.extremeoverclocking.com/t137886.html or  
http://www.hardwareheaven.com/guides/testingPSU/ (You will need a Digital Multimeter for testing your PSU. You want all three rails to be within ATX spec, ATX Specification: 12V: 11.40 to 12.60,  5V: 4.75 to 5.25,  3V: 3.135 to 3.465. If any of your rails hit the minimum spec I would replace the PSU with a new one.)   
HOW TO: Properly load your system when checking PSU voltages.    
#1 Download & Install Prime95   
#2 Download & Install EVGA OC Scanner X   
#3 Open both Prime95 & EVGA OC Scanner X. (Run Small FFT test for Prime95. Run stress test Furry E @ 1024x1024 with 8x AA. Run both of these tests at the same time while checking voltages.)

ok thanks for the help.
 I will follow thru this
 

No problem. Have you checked your CPU & GPU temps as well? No overheating?

PoolKing
heat is very low.
the psu is a themaltake 750 modular, I have seen bad reports about this psu,
as I am getting set to do a full upgrade, I started with the oldest part which was my gpu.
if to fix this problem I need to get a evga psu I will do this and continue to get upgraded.
looking at a
 
120-G2-1000-XR - 1000W EVGA SuperNOVA 1000 G2 Full Modular 80PLUS GOLD 90%+ Eff' Continous Power PSU 
or
120-G2-1300-XR - 1300W EVGA SuperNOVA G2 80PLUS Gold 90%+ Eff' Full Modular Power Supply
 
the 1300w maybe over kill.
 
would one of these psu fix my issues

I'd get the 1300w for future proofing. Yes, getting a new PSU should fix your problems if your PSU is the problem. If you run prime95 and evga oc scanner both at the same time does your system crash & reset?

It is the PSU, I had a Tough Power 750w and it was crap, same issue
on 3 different PSU's (RMA'd 3 times). Last one I got lasted 4 months before
it completely died.
Thermaltake PSU NEVER AGAIN!

Thanks iamSneaky.
That seems to be what I have found out too

PoolKing
looks like i'm going for one of these.
 
860W Corsair AX860i Digital, Full Modular, 80 PLUS Platinum, 92% Eff', EPS 12V, SLI/CrossFire

Good choice, I actually want to get that same unit later on to replace my dated Corsair TX750 80+ Bronze just because I'm trying to make my systems as energy efficent as possible.
