HI! im just new and my english can be bad, but i'll try to explain my problem

Asus p5k pro
c2d E8200
2x2gb PDP LLK
corsair hx 520W
win xp

month ago i boutght HIS HD 3850 IceQ 3 Turbo and since then i have problems, i have "gray screen" 1 time per day sometimes per 2 days, but its always the same and it mostly happen when i surfe on internet very seldom when i play a game, 3dmarks, memtest passed fine! no artifacts etc.

what i tried:
install clear system
tried different graphic drivers
turned off integred motherboard sound card ;)
installed new LAN card
set PCI frequency on 102 and 98

one thing yet, that specificationf of my computer is new, i had the same problems with
a64 3000+ s939
asus a8n-e

i thought that maybe is something wrong witch compatibility, but when i changed processor, motherboard and ram problem didnt disappear :(

temperatures are ok maximum 70C for GPU

also i tried to set clocks lower than default but i had problems with that becouse atitool and atitrytool crashed system when i tried to set clocks, finaly rivatuner worked but ther was another problem, i had 70C for GPU in Idle :( with lower clocks :(


is there something i should try yet?


now i dont know what to do, i will try to give this card to service but i dont believe that will find the same problem becouse its seldom :(.

  1. Same problem here on my girlfriend's computer:

    Asus AM2-VM
    Athlon X2 4000+
    HIS HD 3850 IceQ 3 Turbo 512Mb
    2 GB Corsair XMS2 DDR2-800 C4
    SilverStone Element 500W 80+

    Need help !!!
  2. I own the same card and experienced the same problem. I had to set the fan speed up to 60% with RivaTuner, reboot, and then alter the clocks to get it to work right.

    Also check and see if the power cables are plugged in securely.


    My System:

    AMD Phenom X4 9850 BE at 2.8GHz
    MSI K9A2 Platinum
    HIS Radeon HD 3850 Turbo 512MB (775MHz Core, 1050MHz Memory, never goes above 60 C with 60% Fan)
    2GB Super Talent DDR2 800 (CL 4-4-3-8)
    OCZ GameXtream 600 Watt PSU
    Windows XP SP2
