Hello everyone. Maybe it started yesterday when I got a black screen when the computer started. I waited for a while and I finally was able to enter. I have a problem with my network, apparently. Please look at the picture I joined to this post. Today I tried to log in to Windows Live Messenger and I couldn't, it freezes every time I try to log in. I don't have access to the shared files I have on my other computers, through my personal home network. I can open Skype but it will not connect. I cannot open Norton Antivirus. I ran an online virus scan. I can't do anything. I need you help, please. I tried to open the control panel and I got this error : 1727, 0x06BF, The remote procedure call failed and did not execute. I can't open any folder. I'd like to restore the system...I don't know what happened. I didn't do anything wrong. Last night, I just shut down the computer I worked perfectly. This morning I wake up and nothing is working...I don't understand. Thanks again for helping me. EDIT: I tried to start the computer in "Safe mode" and all the problems disappeared. I'm running a Norton Antivirus Scan, just in case. The online scan just found a "cookie atlas". I don't think it was what's caused all this.
