5850 Crash with most of my games

I'm no expert but you say you just built this computer? Have you gotten all the latest drivers?

Hello and welcome to the forums  
As bnot said make sure you have the latest VGA drivers installed

the games crashed while your CPU & GPU where OC? or stock?
what PSU do you have?
what are your temps during gaming? use HWmonitor to catch high temps

I believe so, but I will try to do a clean install again

during OC, it goes to 51 degree

both, when in stock and OC. i'm using 750W PSU. the temps are pretty high, 43 degree celcius, 110 Fahrenheit. that is based on the ASUS smartdoctor.

looks like you are fine with power
43c on load is rather cool so your GPU is not over heating (or is 43c your idle temp?), what about your CPU temps?

is your RAM brand new? you could have a bad stick.

Please clarify more,is your idle temp 43 ? or full load ?
Also download and install memtest and check your RAMs for about 8hrs and check whether it reports any errors or not

okay just got back, i'll update you guys later

how do you use the memtest?

Burn memtest image to disc and reboot from your new memtest disc.You could run it for 8hrs but it's not really necessary.Load your first test with just one memory stick,that way you can isolate which module if any is the culprit by testing one module at a time.
If any errors are detected you will see red text.
I had the same problems as you're having a couple of months ago after adding 2 new modules of memory to an existing set-up.
Turns out one stick was bad and i had to rma both modules.Caused nothing but grief until rectified.


Cpu - Intel i-7 860
Mobo - Gigabyte P55-UD5
Mem - Corsair Dominator 1600CL8\ 8 GB
HS - Thermalright MUX-120
GPU - XFX 5850 Black
Psu - Corsair HX 750
Sound - Auzen Forte 7.1
Case - Antec 902
OS - Windows 7 Pro 64


Good luck!

GPU: -stock 38 -full load 77

CPU: stock 36, full 46

it seems to be fine now... after did a clean install.. i'll test it with other games as well..

If you have further problems you might try downloaded DriverSweeper to clean up ati files in safe mode then reinstall Catalyst 10.4 it has worked for me to solve gpu issues

Your temps are fine,let us know how it performs in other games when you tested

What I did before, using drivesweeper for to clean up all the drivers and reinstall for the new catalyst.

sigh.... it works at first, but the problem starts again when I tried to play the same game tonight. It started to stuck, not running smoothly....

Did you do try with memtest too ?

Just wondering what brand of PSU are you using e.g Antec etc

i'm using Corsair 750. Haven't done the memtest yet. gonna do it now

My build is less then 6 months old and i had all sorts of issues which caused nothing but BSOD's and grief. I know the frustration you're feeling.
This was my first build and going into it i was intermediate level as far as skill goes.
Issues seemingly unrelated will absolutely effect your gaming experience.
After i rma'd my cpu,hdd,and memory i had a smooth pc.
Memtest is a must to troubleshoot your system ramm.
If your ramm turns out fine the next thing i would do is clear your mobo cmos and start with a clean bios.
Check for any mobo bios updates and go from there.
I've done that before and it totally fixed gaming issues concerning my display stability.


Good luck! i hate it when i have gaming issues!

thanks dav, hmm weird.... i deleted the gamer osd utility software and OC my graphic card... everything seems to run smoothly afterwards....

I'm glad to hear that worked for you .
I once added some extra utilities to my mobo from Gigabyte and they caused nothing but problems for my system.
Once they were deleted i reset my onboard cmos and everything returned to normal.I've heard this is quite common when adding mobo manufacturers utilities.
Your better off to monitor and adjust your gpu with the Msi Afterburner,GPU-Z ,and CCC.
These are all reliable and won't cause you problems.
I'm glad i could be of assistance.

Cheers!
