Hi all, I have a Dell Inspiron 531 running Vista which I bought last January and there has been a persistent problem ever since I bought it. It will spontaneously freeze, first with the toolbar then with the program I'm running although it can vary. It then freezes entirely and any audio I have will start to stutter - rapidly repeat a second of the music - and if left for a while it will go to a blue screen and give a message of either KERNEL_STACK_INPAGE_ERROR or KERNEL_DATA_INPAGE_ERROR. This first happened the night I first turned the pc on so it is certainly not something I have downloaded onto it. Also it has increased in frequency to freezing every ten minutes or so. Would reinstalling Vista perhaps help? I am a student and can't afford a new pc, I really need to resolve this so any help would be greatly appreciated.
