Hello. I have HP Pavillion laptop. I also have Vista. I have never had this issue before. But when I put my computer to sleep, i can wake it up but there will be nothing on the screen and I can't do anything. When I close the laptop and open it, it gives me the same issue. I set it to sleep when I close the laptop. I think it may be due to a recent file that I deleted. Every time I boot my pc I get this icon in my taskbar that says some start up programs have been blocked. In my case there was only one. I don't remember what it was called but I do know that it starts with the letter "g" and ends with a number. What can I do?
