Windows 7: BSOD Locale ID: 2057

Hi, my Dell 1558 continues to crash with Locale ID: 2057, sometimes it crashes with a black screen and the speakers make a rumbling sound then restarts, othertimes its a black screen and multi-coloured lines, and now its crashing when I log into windows! So i'm now writing this in safe mode. I've attached two of the error messages below and attached three dump files.
