Sounds like a corrupted OS install. Could be caused by a number of things like: virus, failing Hard Drive, system lost power while doing an update, etc. Very hard to diagnose such a problem without being in front of it.
If the system will not complete boot, try the F8 boot menu and select safe mode and see if the system will boot to windows.
If the system boots to windows, you could have software issues or a startup item causing the system to hang at boot, try turning off the startup group items in MSCONFIG (Start, run, MSCONFIG) and see if the system will boot in normal mode.
If that is not help, hold the Fn Key while pressing the power buttong this should start PSA diagnostics on the system, see if any hardware fails
it looks like the Inverter's gone in your screen, it works like a starter in a florescent tube, it 'kick starts' your screen to come on. Turning it on/off many times eventually 'kick starts' your screen and makes it come on eventually.
If the issue occurs in the safe mode, then I'm suspecting a failure of the LCD backlight. (It warms up and quits) Also see if video stays on using an external monitor. If it does, then the LCD is most likely failing.
If video goes out on an external monitor as well, then the Video card is failing due to overheating. Make sure all vents are free of dust (Clean with canned compressed air) and the all fans are functional (Run the fan test in diagnostics) If fans check up, then video card is failure point. If fans fail diags, replace affected fan 1st
Its failing to go through the full boot process. Try pressing F8 on boot until the boot option screen comes up and then select safe mode. Follow this though until you are given the option of using system restore instead of safe mode. take that option by clicking on the NO button. Restore the machine to a date some time a few days previous to the fault developing.
If that fails then put in any OS disc and boot from it. select R at the first options screen, follow it through and then select the C drive option. Just hit enter when asked for admin password.
now type chkdsk /r (copy and paste this to be sure). let it run and then reboot and see what happens
