Apparently a icon popped up and ask him to download something and then restart his machine. When he restarted he got the BSOD.
*** STOP: 0x0000007E (0xC0000005, 0xF85F9AD9, 0xF898B7A4, 0xF898B4A4) BUT the numbers and letters are different then these in the example Ive used above. But the Stop error message is the same.
Any help will be much appreciated
