    Screen turns black, and HDD light goes off, BSOD file included, Thanks


    Hi, hope you're doing well.

    this just started happening to me yesterday. Windows 7, 64 bit. I'll be doing nothing in particular on my Toshiba Satellite laptop and the screen will randomly just turn black...the back light is still on. The hard drive light on the front will also stop blinking and just turn off. I have to manually shut down my laptop by holding the power button....I can restart it normally but then after a random amount of time, the screen will turn black again. It might last 15 minutes or an hour but it happens again. I've included the file requested for BSOD situations because I"m not sure of the issue.

    Thanks for any help, I truly appreciate it!

    Welcome to SevenForums.

    Is the laptop heating up or warm?

    For monitoring the heat/celsius of the system, use Speccy or HWinfo:


    Update the graphics card drivers:
    Code:
    Driver	c:\windows\system32\drivers\atikmpag.sys (8.14.1.6099, 184.50 KB (188,928 bytes), 5/28/2010 12:56 PM)
    Click on the Start ► Control Panel ► Programs ► Uninstall a program ► Uninstall everything related to; ATI. Delete remnants of its drivers/older drivers using Driver Fusion/Sweeper. Then download and run this tool: AMD Driver Autodetect.

    Update the drivers for the sound card:
    Code:
    Driver	c:\windows\system32\drivers\chdrt64.sys (4.112.0.0, 701.05 KB (717,880 bytes), 2/1/2010 2:45 PM)
    (From here or search in google for appropriate version)

    Uninstall Norton, it's a frequent cause of BSOD-s. Use Microsoft security essentials and Malware bytes (free). Make full scans with both.
    Do not start the trial version of MBAM, untick the option before proceeding for updates.

    Run the System File Checker that scans the of all protected Windows 7 system files and replaces incorrect corrupted, changed/modified, or damaged versions with the correct versions if possible:

    • Click on the
    • Type CMD on Search
    • Left click and Run as Administrator
    • Type SFC /scannow

    Full tutorial here:

    Free up the start-up, nothing except the antivirus is usually needed.

    Run Disk Check on your hard disk for file system errors and bad sectors on it:

    Look for an update on the BIOS:
    Code:
    BIOS Version/Date	Insyde Corp. 1.50, 5/14/2010
    Code:
    Version	6.1.7600 Build 7600
    Install all updates, optional updates including Service pack 1:

    Hey thanks a lot for your help, I really appreciate it. I did all you mentioned and the sound problem is gone. Didnt get a black screen for 24 hours either....not sure what caused it this time. Seems like things are better overall though, the one thing I notice is that now when I boot up and long in the command prompt pops up for like a second and then disappears...does this mean anything? Should I upload another zip file?

    Thanks!!!

    Yea, I've ran malwarebytes, combofix, and the windows security essentials scan. After I ran all those and updated the drivers the command prompt thing started popping up after I log in. the black outs are definitely more sporadic but still occurring every so often.

    Thanks again for your advice, I can post another SF diagnosis file if you think that might help and narrow things down.

    Looks like the motherboard and CPU are heating up a little.

    Is this a laptop or a desktop?
    How old is the hardware?
    Is any part under warranty?
