Hi there

I'm currently having problems with my computer its an older desktop running windows 7, keep getting a Blue screen of death its has only recently started doing this, and it doesn't seem to be any particular application however the blue screen doesnt stay up long enough to read and resets. I have some dump files I was wondering if someone could read them for me and maybe give me some feedback as to what the problem might be. there are several instances so I have only included three.
Any help would be much appericated.
here are three dumps.
