1. If you do not already have the Operating System (OS) software, download and burn it to a cd or make a flash drive bootable.
2. Put in the disk or plug in the flash drive and Turn off the computer.
3. Turn on the computer, and as soon as you see the samsung logo, Press Delete (around 3-5 times). And you should get to the BIOS screen.
4. In the bios, look for startup/boot options and set the first boot device to CDROM or if booting from a flash drive choose Removable Disk.
5. Save and quit the bios and the computer will reboot.
6. Once the computer passes the Power On Self Test (POST), it will automatically check for the first boot device (CD or Removable). If found, it will prompt you to boot from the boot disk. Press any key or Y for yes.
7. Follow the prompts from there.
NOTE: It is usually best practice to do a clean install removing any prior data from the hard drive.
Verify monitor operation by UNplugging it from the computer and turning it on. A "Self Test Screen" shall appear (if it doesn't, the monitor is faulty and must be repaired).
Assuming it worked, plug it again and turn it on. After half a minute or so, turn the computer on. You should be able to see at least the BIOS POST screen: if you don't, there could be something wrong in the computer video board (maybe misconfigured, or set to output to a different, possibly internal, head - I saw it once with a Matrox VGA). Refer to the VGA manual for that.
If the POST screen appears, the problem is perforce in the OS VGA configuration. Assuming it's Windows, you can get into the safe mode boot screen by pressing the F8 key at boot, and once booted, access the video resolution configuration from the Control Panel. Set it back to something surely working, in your case 1024x768, and work it up from there.
If the CD drive door won't open, odds are that at least you know the drive is without power. Have you had the case opened up at all? With what you've described here your computer needs the tender, loving care of a technician.
Take your battery out, leave it out for 5 minutes and try it again. If the same thing is happening afterwards, and you are able to, connect an external monitor to your laptop and use the function key to try and switch to it, and see if that works and if there is anything showing up on it.
First try to do monitor self test.Disconnected the blue cable VGA or white colour connector from monitor to the computer. Turn on the monitor and check if you are able to see colours or line on the monitor.Indicating self test monitor is working fine. If you are using Video card on computer connect monitor directly to onboard video and check. Good Luck.
I had a similar problem with a Dell Computer. It turned out to be a bad memory card. If you have more than one memory card in the machine, take all of them out except for one. If that does not solve the problem, try swapping memory cards.
Your monitor provides a self-test feature that allows you to check whether your monitor is functioning properly. If your monitor and computer are properly connected but the monitor screen remains dark, run the monitor self-test by performing the following steps:
Turn off both your computer and monitor.
Unplug the video cable from the back of the computer. To ensure proper Self-Test operation, remove both Digital (white connector) and the Analog(blue connector) cables from the back of computer.
Turn on the monitor.
The floating 'Dell Self-test Feature Check' dialog box should appear on-screen on a black background if the monitor cannot sense a video signal and is working correctly. While in self-test mode, the power LED remains green. Also, depending upon the selected input, one of the dialogs shown below will continuously scroll through the screen.
This box also appears during normal system operation if the video cable becomes disconnected or damaged.
Turn off your monitor and reconnect the video cable, then turn on both your computer and the monitor.
If your monitor screen remains blank after you use the previous procedure, check your video controller and computer system; your monitor is functioning properly.
The part where you see some color bars and blinking green led is what we call MONITOR SELF TEST. A diagnostic pattern consisting of four colors (red, green, blue and white) appears, and the LED flashes slowly. this happens when signal cable from the monitor is disconnected from the tower and leaving the power chord for the monitor plugged in. If the monitor works properly on a different computer. then its a problem with the computer's video card sending out signal. im 85% sure that its a problem with your video card.
