Few issues with ATI Radeon 3850 HD

  1. Hello everyone. :wave:

    I'm new here and I need some help with my computer. I hope to get some help if that's possible.

    I upgraded my PC few months ago. So my current configuration is:

    Gigabyte GA-MA770-US3 v2.0
    AMD Phenom 9500 Quad-Core Processor(4 CPUs), ~2.2GHz
    Kingmax 4096MB RAM
    ATI Radeon HD 3850 Series, 512MB
    Seagate Barracuda, 640 GB
    Samsung SyncMaster P2250
    Power Supply 600 W

    Its a custom made PC, I bought everything on my own hand. I thought everything should work fine. And everything did work fine. But problems started while playing games.

    When playing THPS: American Wasteland for example, game runs perfectly. But at some point (its usually randomly), whole pc crashes. I get black screen and pc is still running. I cant reset it on reset button like usually. I have to hold power button few seconds until it shuts down. And then when I turn it on again everything works fine.

    Any idea what could cause this kind of problem?

    Also before that I had same configuration but different motherboard, instead Gigabyte GA-MA770-US3 i had GIGABYTE GA-MA770-DS3.
    I donno what happened to DS3 version actually. I turned it on and i got black screen, i could feel the smell of burnt electronics. Tried it on my friends PC, it didn't want to start also. So i guessed something burned up. So i bought US3 version.

    I did not reinstall my OS since DS3 version. I only installed drives for US3 version, and everything else was the same. But now my windows freezes randomly. Sometimes after 1 hour. Sometimes after 10 hours. Is this because i didn't reinstall the os when changed to US3 version?

    Last but not least problem is my graphic card. ATI have some shitty powerplay option. It slows its GPU to 300MHz. When playing some games in window mode they run very slowly. GPU doesn't want to go over 300MHz. I tried overdrive in CCC but its not working. Nothing happens when i move slider and press ok. When i put auto tune, sometimes my pc just freezes and i have to reset it (freezes same way it does in 2nd problem). Is there any way to remove this powerplay option.

    Also sometimes my direct 3D fails. Might be problem with ATI drivers. Anyone have an idea?
    Direct3D 7 test results: Failure at step 39 (SetDisplayMode to 640x480x16): HRESULT = 0x80004001 (Not implemented)
    Direct3D 8 test results: Failure at step 8 (Creating 3D Device): HRESULT = 0x88760827 (error code)
    Direct3D 9 test results: Failure at step 8 (Creating 3D Device): HRESULT = 0x8876086c (error code)

    Any help would be greatly appreciated. Thank you. :)

    "I did not reinstall my OS since DS3 version. I only installed drives for US3 version"...

    It is never a good idea to move a current Windows installation to another motherboard with out doing a fresh OS install. Many other things can cause your problems though...

    Video driver
    power supply
    Over-heating issues

    I dont have dvd drive so i couldn't reinstall it....

    I checked temperatures, everything is fine except motherboard. Southbridge is burning on 80C. I don't know if that's high for this specific motherboard.

    I think it might be power issue. I have TV, DVD, clock, lamp, video recorder, speakers, printer, monitor, pc, modem and many more thing connected to 1 single power jack.

    80C is hot. Was there ever a heat sink on the south-bridge? You may be able to use a USB DVD drive or even use an 8GB USB flash drive to reinstall Windows if needed

    Yes there is a big heat sink on south bridge, and when i touch it i can burn my finger on it lol

    I tried reinstall from flash drive but i got some weird error. I probably did something wrong...
