Operating System: Microsoft Windows XP Professional [Service Pack 3] Hi, I have various problems all of a sudden which i hope u guys can help me. 1.) i cant copy/paste files or folders or anything, i've tried right click copy, and when i right click and wanted to paste, the 'paste' is grayed out and im not able to paste anything. i've also tried ctrl-c ctrl-v which doesnt work too. And i cant drag the files or folders too. 2.) i cant open my internet explorer, when i click internet explorer, the window just open and close immediately in less than a sec. 3.) when i minimise my windows for any applications, it doesnt appear on the taskbar, the taskbar is always empty. I need to alt-tab to get from windows to windows. It all happed when my PC restarted in my absence might be due to windows update. I would be thankful for any kind of help.
