Zillions of software problems can cause problems like yours. If you have any other symptoms, the more you supply the details about, the better. It could also be caused by a hardware problem. See the part starting..... Something else may be wrong. in response 2 of this: http://www.computing.net/answers/wi... Also - you can have all sorts of problems if the partition Windows is on, which is usually C, does not have enough free space on it - what's the size of your partition (logical drive) Windows is on, and how much free space is on it?? - if your computer is a desktop computer.... Failing power supplies are common and can cause your symptoms. Check your PS. See response 4 in this: http://www.computing.net/hardware/w...
