My computer screen has gone black...?
My computer froze up and upon rebooting it I've found that the screen is totally black. I can type in my password and hear my computer start up, but the screen stays totally blank. What's the problem and how do I fix it?
It starts up when I turn it on (screen remains totally black- no messages or anything). The lights below the screen are on- the laptop even connects to the wireless. I can even type in my password (can't see the box or anything) and hear my computer sign in- the screen just stays black.
Exactly where is the graphics card and what does it look like? How will I know if there's been any damage to it? If this problem persists, would it be possible just to buy another computer and move files from the old hard drive onto the new one? If so, how would I go about doing that?
Sorry about all the questions- you guys have been really helpful so far though...

A few questions for you,
you say you can hear the PC boot so does that mean you see the BIOS data or not? (the White writing on the Black background before Windows starts)
If not then your problem is most likely to be either a monitor failure (is the light green or orange?)
or the cable is disconnected (have you checked it at both ends?)
or the Graphics card is not working (do you hear any beeps when the PC boots?)
If the light is green on the monitor then the PC is producing a Black screen so the Monitor is getting a signal, this suggests another fault elsewhere. If the light is orange it suggests it is not getting a signal or has perhaps failed. It could also suggest the cable is not connected so check it at the PC end and the graphics socket end.
If the VGA card or Chip has failed you would normally get a series of three beeps when the PC boots up, you should get one any way, then a further three if the VGA fails to boot. In this case replace the VGA card, first just pull the card out (PC off) and put it back in the slot, reboot and see if it was just the card not properly seated in the slot.
If you get no beep at all (and you had one before) then your mainboard has failed. A series of short beeps (continuous) then it is a memory failure. A long single beep is a CPU issue, normally this would display a warning notice on the screen though.

Is it a laptop? if yes, ignore all this and take it to a computer repair shop and expect to pay a nasty price, or even buy a new laptop
Is it plugged in and all?
is it turned on?
could the fuse in the socket have blown?
Have you tried a different computer screen? (this is to test if there is a problem with the screen or computer)
If the Second computer screen works, the computer screen is broken and needs replacing.
Ok if it still is not working there is a problem in your computer.
If your lucky its just a problem with the Cable, which will need replacing (unless the Cable is embedded into the computer screen)
If not, the problem is with your graphics card/Integrated chip set
which will need replacing. go to a computer shop. you can get a cheap one that is not too expensive, take the computer if you are not experienced to replace it yourself, and let them do it.
