    Windows Blue Screen Error

    The Blue Screen (Black Screen for Windows 7) is actually Windows’ way of protecting your system when there are software or hardware issues. The Blue Screen prevents your system from carrying on and aggravating the problem.

    With the Windows 7 Blue Screen C5, a message appears saying that a `device driver has pool’. The message adds that you would have to check whether any new hardware or software is properly installed.

    If you’ve performed installation for the first time, you would have to find out from the hardware or software developer ask if there are any latest Windows updates. In most cases, running the latest updates would fix the problem.

    Chances are you would have to run your computer in safe mode. To do this, reboot the computer and when it’s starting up, hit F8, select Advanced Startup Options and then choose Safe Mode.

    Latest Hardware Drivers

    The Blue Screen of Death C5 usually occurs when you don’t have the latest hardware drivers installed, especially in the case of chipset and video drivers.

    With some hardware, finding the latest drivers is a tricky task. There may be various drivers for different versions of the same hardware and for different operating systems. The process of managing hardware drivers could be simplified though with the use of a software program like Driver Genius.

    Driver Genius helps you update, remove, back up, restore and even find new drivers for your system. This professional driver management tool has the ability to locate drivers which Windows can’t and provide you with a download link rather speedily. The program relies on a database of about 30,000 drivers for motherboards, video cards, sound cards, modems, network cards and so on.

    You don’t have to use such a program if you’re used to downloading and installing the latest drivers manually.

    Software Updates

    The next step would be to ensure that you have the necessary Windows software updates including the less-than-critical updates. You can obtain these updates manually with the help of Internet Explorer. This procedure doesn’t work with a non-Microsoft browser like Firefox or Opera though.

    If you’re on Internet Explorer 7 and older browsers, click on Tools and then choose Windows Update.
