Hi, I am hoping someone can help me, I am not exactly very computer savvy and I am home having a heart attack at my blue screen! Was working away and got a Windows Update message to install a service pack for XP - which I did (and am now regretting). Was told to restart, and did. Then when restarted I got the blue screen message. My error is: STOP 0x0000007E (0xc000001D, 0xF78E28EA, 0xF78E27F4, 0xF78E24F0) I have tried to start in all the different 'safe' modes but I can't. It just takes me back to the blue screen. I have a huge report due this afternoon which is on the hard drive of that computer!! I have my laptop (which I am on now) but that won't help get my report. As I said, I am not very computer literate so any help in easy to understand language would REALLY be appreciated!! The computer is a Dell optiplex 745 if that helps. Thanks!
