On the internet and my screen went dark. Got a message, "Some data disk files were lost". What is this?

If you have a bad hard drive and the system cannot write data to it, then you will get this message. I have no idea if it's legitimate or a virus.\n\nListen closely to the computer's hard drive, you can sometimes hear it clicking repeatedly or whining.\n\nBefore you go on the Internet right click your hard drive under Windows Explorer and find the tool that checks the drive for errors, it'll soon tell you.\n\nIf the drive is good, invest in some good anti-virus software.

Could be.\n\nTry rebooting the system. That might help.

it is a dead cell on your hard drive. That is usually a virtual memory error but sometimes a dead ram address.

The hard drive may have failed. Go in to the BIOS and see if the drive is found.

I think you should start copying your files....!I too lost my hard drive and lost all the data...!I can give you a link that deals with hard drive problems. Some RAM/hard drive problems can be easily fixed yourself by using easily available tools. I found the info at http://fixit.in  useful. Try this site, if you can get what is required.

Probably means you hard drive is having problems and getting ready to die. Time to backup your data.

Oooo, bad noises. If it was a problem with the circuit board I could give a suggestion, but those noises mean that the "heads" that read the data off the platters were hitting something inside the dirve, and from your description of the sounds, I'd say what they were hitting was the platters, where data is stored in a hdd :( Bad news, that. Some of your data would probably still be recoverable, but not at home, not without a clean room. There are companies who specialize in this, but it's expensive, and they usually charge by the megabyte. Google "data recovery specialists" if you want to find one near you.

I'm not saying your problem is what mine was, but last Friday my Dell laptop started doing the same thing.  It would go to the black Windows XP screen and then it would just go black.  And stay black.  I found out the next day, after having the Geek Squad people at Best Buy look at it that it was my motherboard.  I had let the battery die and when I plugged it in, sparks flew up from the surge protector and they said that's probably what did it.  Had to buy a new computer.\n\nIf you have any friends who are good with computers, ask them.  \n\nBut if it is something that can't be fixed, those people were able to transfer all my files (not programs just files) from my old computer to my new one.\n\nGood luck - I know exactly how horrifying that is!!!!

Tough to diagnose without knowing what kind of file it is.\n\n\nWhat is the full file name?\n\nI would also try to download it first, then open it, intead of opening it up from the internet.

This could mean many things. It could be a process unable to access a file in your harddrive, a mouse/keyboard prob,  or it could be problems with your harddrive.  You'll have to dig a little deeper in order for us to help you.\n\n*Go to Start=> RUN => Under Open:, Type eventvwr.\n*This is your computer logs.\n*Click SYSTEM, and locate any errors that may say..\n I/O subsystem was invalid, etc.\n*Just check on other information that points to the I/O error.  Take down the error message and ID # and send it our for answers later.\n\nFYI, you make have to run chkdsk /f on the command prompt or maybe just a quick defrag.\n\nGood luck.

Maybe you have "System Restore" disabled in control panel/system.
