safe mode

My computer is in safe mode right now but with network, I can still talk with my sister online but I couldn’t use the webcam and I can still do my blogging thing. It’s very frustrating because if I restart my computer and use the regular one, it screwed up everything. I can’t connect my internet, always hang and its very slow. I restart my computer many times but it doesn’t help. Why this thing happen? I have a lot of things to do online. Well, I guess I will use the safe mode with networking for awhile until everything will come back to normal. I already update the windows, anti-virus, defrag my computer and do the disk clean up but its still the same. I might need to restore my computer and see what happens.
