Hi, I googled the web and was unable to find any solutions to my problem. So really hope that someone here can help me My system is running very normally and smoothly without showing any signs of slowing down, but I still face the following problems: 1. Ctrl-Alt-Del not working 2. Task manager not launcing 3. Not able to get into Safe mode 4. System restore also fails to launch I scanned my computer using the latest updated AVG Anti-virus, Spybot-SD and Adaware and I cleared whatever problems that they found, but I'm still faced with the same problems above. I will be posting my log file later. In the meantime, can anyone suggest anything that I can do? Thanks a million.
