Helping people with computers... one answer at a time.
I'm hoping that you have backed up. If not, this is a very good reason to do so. We don't know that your data hasn't been completely overwritten!
I went to grab a file from my wife's computer that I've done thousands of times. The screen showed them, and then the screen went blank. All of the icons went away. The screen is just white now. This week, last week, they've not come back. I've no access to her files now. Any idea what happened? I'm running XP Home, SP 3. In fact, we both are. I gave up on Windows 7 when nothing worked.
In this excerpt from Answercast #64, we look at what happens when a screen goes white and what that means.
So when you say that the screen just went white, I'm assuming you mean the entire computer screen. That there is nothing at all visible on the screen whatsoever. There's no remnant of Windows.
To me, that says either of two things:
Either your computer simply crashed and it's not coming back;
Or the connection to the monitor's been harmed and it can't display properly what you're computer is trying to display or the monitor itself has failed.
So, I'm assuming that you've tried rebooting the machine. If not, reboot the machine.
If that doesn't solve anything, then I would do something like take the monitor and its cables and try them on a different computer - to make sure that they're working. Or the other way around, borrow a monitor, connect it to your computer, and make sure that's working or not.
If the replacement monitor works, that tells you that your monitor is toast. If your monitor works on somebody else's computer, that tells you that the problem lies elsewhere.
I'm hoping that you have backed up. If not, this is a very good reason to.
It's unclear exactly what's going on. We don't know, for example, that your data hasn't been completely overwritten. So, one lesson to take away from this is of course to start backing up and backing up regularly. That way, you'll have access to your files, your wife's files, whatever, on a regular basis no matter what happens to your computers.
Finally, the other thing that comes to mind for self-diagnosis would be to go out and grab what's called a "Live CD." It's something that you download and burn to a CD-ROM and boot from that CD-ROM. There are several:
Ubuntu Linux is one (that might require a live DVD; they just exceeded the size of a CD). But there are others.
There's the Ultimate Boot CD.
The bottom line there though is to see if you boot from some other operating system. Does the display work? Can you see what's on your hard disk? Does the computer work at all?
If it does, then you've at least defined the problem to be probably, software related and not hardware related. If the live CD doesn't work at all, then you've probably got yourself a hardware problem.
Unfortunately, given the description we're working with, about all I can suggest you do in either case (software or hardware) is that you then consider seeing if you can't find yourself a good local technician to have a look at the machine. This definitely feels like one of those situations where you want to have someone lay hands on the machine, examine the machine, poke around on the machine physically, and see what's going on in a way (obviously) like I can't do here from the other side of the internet.
