My computer froze for a couple of minutes last night, and I was impatient and just went for the power button. The thing is, I have not managed to turn it back on since then. It gives me some safety options when I try switch it on to login, but those just give me a blank screen. What is a man to do?
Print these instructions before continuing. They will not be available after

In the Shut Down Windows dialog box, click Restart, and then click
When you see the message Please select the operating system to start,
Use the arrow keys to highlight Last Known Good Configuration, and
then press ENTER.
If you have a dual-boot or multiple-boot system, choose the installation

Choosing Last Known Good Configuration provides a way to recover from
problems such as a newly added driver that may be incorrect for your hardware.
It does not solve problems caused by corrupted or missing drivers or files.
When you choose Last Known Good Configuration, only the information

made in other registry keys remain.

1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.
if you press ctrl alt delete, sometimes the computer will reset itself. You might need to wait for a few minutes until the computer does its thing.
if the computer is not moving or you are getting impatient(I am usually impatient). I would usually press and hold the power button of the computer so it shuts down for me. Then I would press the power again so the computer will turn back on.
PLEASE BE WARNED - if you were doing something before this, you will lose your work, and there is a slight chance that the computer might not start back. If it does not start back usually it is a virus or a hardware problem.
hi, take out the power cable from the system press and hold the power button for 15 seconds and then put in the power cable and try to start, if does the same behaviour again you should contact dell technical support because it might require multiple steps of troubleshooting

One reason that this is happening could be that it is on Power saving mode. This happens when the LCD monitor detecs an incorrect timing then thats the time that the LCD goes blank and the power botton starts to blink.
what you need to do is to turn the computer off. Unplug cables attach to the LCD make sure it is also off, once done press the power botton for a couple of 30secs to a minute and then release. After doing so re-connect all the cables and make sure that both ends is tight and secure once everything is ok turn the computer on same with the monitor to check if it solves the problem.
