Hi there, I've had the same problem as this guy: http://www.techspot.com/community/topics/black-screen-after-desktop-loads.146290/reply I followed the instructions given, but now instead of having a black screen after 10 seconds of Desktop loading up, I get vertical blue and white lines all across my screen. Combofix said I had avast running but I couldn't find the program running anywhere, it was gone from my processes as well. Do you need any of the logs I've taken with the programs mentioned in the thread? If its easier to re-instal windows at this point, please let me know. Thank you, -Werner Edit: well, I just now read the sticky above that says not to try suggestions given to other people. Unfortunately, the thread I copy/pasted was given to me through a Google search while trying to solve this problem, thus I did not see the stickied warning thread before reading the instructions... Apologies.
