I have windows vista 64bit home premium. When I try to open up applications, close them, open something within everything freezes. I can use control alt delete but can only log off and log back in normally again until I open something and freezes, or reebot, shutdown what have you. I mean anything I try to open freezes. The start menu. I can get it to open but if I try to open a program from it, it freezes. I did a chkdsk run on my hard drive, it's good. Scanned for viruses and spyware that's good. I can not use system restore or open task manager to see if anything is wrong. I have opened the device manager but I don't seem to have any compatibility issues. Everything is up to date from widnows update. I am not sure what it is but I have a grey globe shape icon with grids on the icon on my bottom right bar. I can open firefox/IE and surf the web though..... Doesn't make sense. I am using an HP Pavilion DV7 Laptop with 4gb ram, onboard hd ati graphics. Anyone have a solution? Never encountered this before. Thanks.
