Ok, windows starts up, gets onto the desktop then the mouse flickers and the blue screen of death appears; Event Log - The computer has rebooted from a bugcheck. The bugcheck was: 0x10000050 (0xffffa5f8, 0x00000000, 0x8054a51a, 0x00000000). A dump was saved in: C:\WINDOWS\Minidump\Mini062607-11.dmp. Mini Dumps - Attached below. Sorry for asking for help my first ever post, but I really need to get this bug fixed, don't fancy reformatting my hd as I have many valuable photos on it. Cheers in advance.
