My computer has been going to a black screen starting two weeks ago. I have Norton and have restarted in safe mode, run system restore and done a full scan with Norton repeatedly only to have it go black again. At one point I actually had to uninstall and reinstall Norton. I came across this forum and have followed step one: run Norton, it says I have risks, fixes them, restarts to a black screen again. So, I then downloaded Microsoft Security Essentials to SD card, installed on computer and it came back that it cannot complete, sends error report and upon restarting goes to black screen again. I moved on to install MBAM from SD card (downloaded from other computer) and it ran quick scan successfully, found 23 risks, I saved the log and deleted risks and upon restarting it is back to a black screen giving me the option to start normally or use system restore (no safe mode option). I started normally and got a black screen again. Not sure what to do from here. I do not have the log to paste here as it is on the computer with the problem. Any suggestion?
