Hi-- I am extremely frustrated. I have a Dell Latitude running XP Professional and am having a recurrent problem. If I leave the computer on and it goes into standby or hibernation mode, sometimes it will not boot up afterward. I get a black screen and a flashing cursor in the left up-hand corner. My IT have not been able to figure it out and doubt what I tell them (regarding the events prior to this happening). The only way they can "fix" the system is to reinstall Windows. I know there must be a hardware problem or software incompatibility (with Windows XP), but I want to get to the bottom of this once and for all. My IT people are ready to ground me. I should add that I all was well until I got a bad virus/spyware, they had to reinstall then. Then they found that my HD was failing so replaced it. They checked the hardware and everything checks out. Can someone please help?
