Ive been playing SC2 since it came out in stores, and I recently moved to a new PC, which has windows 7, 64-bit OS. Since, then, I've been randomly experiencing errors while playing SC2, that say: "Your starcraft 2 installation file is corrupt, would you like to run the repair tool now?" I run the repair tool, and it says that no problems were found, so I then try to get back into the game, and it immediately crashes at the same spot that it did the last time. I googled the error message, and found another person on here who had the same problem, and he was told to post a dxdiag, and to run a check disk. I ran the check disk, and found no problems. So I am going to post the dxdiag here and see if you can help me. I'm not overly great with fixing these things, so try to be relatively simple with your answers. Thanks for the help in advance! View attachment DxDiag.zip I really hope this is the way to post an attached file...
Did you build this machine yourself, or is it store bought? If it is store bought, can you post its make and model? The motherboard installed is the Biostar TA890GXB HD. There have been 2 new BIOS updates since launch, one that improves "SATA3" function, I highly suggest you install the newest BIOS dated 2010-07-19! On restart after flashing, enter the BIOS by pressing <DEL>. Then go to the "Exit" tab and select "Load Optimal Defaults." Then go to Chipset, NorthBridge Configuration, Primary Graphics Controler, and make darn sure that you pick an option where "GFX0" comes first. This way on boot, the first card checked for a display is always your ATI 5600. Then go to "Internal Graphics Configuration" and where it says "Internal Graphics Mode" select the mode to disable (this will redisable your onboard video after the resetting everything to default). Go to Exit and "Save Changes and Exit" then boot into Windows. This isn't the last thing you will have to do in the BIOS, after installing the AHCI driver (below), then follow this guide here to enable AHCI (This is the high speed driver for your hard drive). In the step that says to enter the BIOS to enable AHCI, this is what you need to do. Go back to chipset tab, then go to "SouthBridge Configuration," and select "SB SATA Configuration." Go to "OnChip SATA Type" and change that to "AHCI." Go to Exit tab and "Save Changes and Exit." If your AHCI conversion goes well, you may have to reactivate Windows. I would install ALL of your drivers before enabling AHCI. After all of that is installed, you have tons of missing drivers for your motherboard that do not appear to be installed. Install the following: Chipset On-Board LAN for Windows 7 Serial ATA AHCI/RAID for Windows 7 Install the following if you have an a remote control for the computer: CIR Driver BIO-Remote Utility Go to Realtek's audio download site and download the following: Vista, Windows7 Driver (32/64bits) Driver only (Executable file) ATI HDMI Audio Device If for some reason, all of this doesn't fix the problem, run Memtest86+. I highly suggest using the USB stick method since it is much easier. Just make sure you have your data on the USB stick backed up first! I don't know if you can do Hybrid CrossfireX (which from what I understand like Hybrid SLI for nVidia, should let you shut down the higher end graphics card and use only the onboard for normal task like browsing the internet and watching DVD/Blu-Rays.. saving you a ton on electricity). We'll try getting this machine stable before we think about anything like that.
